lib/utils/services/get_current_location.dart (1)
122-134: Timeout not enforced: Future.any ignores the timeout error until all futures failFuture.any completes on the first successful result and ignores errors until every future errors. Your delayed error won't trigger a timeout if getCurrentLocation eventually succeeds. Use Future.timeout instead.
Apply this diff to enforce the timeout:
- Future<LocationInfo> getCurrentLocationWithTimeout({ - Duration timeout = const Duration(seconds: 30), - }) async { - return Future.any([ - getCurrentLocation(), - Future.delayed(timeout, () { - throw const LocationException( - "Location request timed out", - LocationErrorType.locationUnavailable, - ); - }), - ]); - } + Future<LocationInfo> getCurrentLocationWithTimeout({ + Duration timeout = const Duration(seconds: 30), + }) { + return getCurrentLocation().timeout( + timeout, + onTimeout: () => throw const LocationException( + "Location request timed out", + LocationErrorType.locationUnavailable, + ), + ); + }lib/utils/services/wallet_provider_utils.dart (2)
24-27: ABI encoding bug: boolean “true” encoded as chain ID “11155111”Returning 11155111 for true is incorrect and appears to be a copy/paste of Sepolia’s chain ID. Booleans in ABI encoding should be a 32-byte word with 0 or 1.
Apply this diff:
- } else if (type == 'bool') { - return param.toString() == 'true' - ? '11155111'.padLeft(64, '0') - : '0'.padLeft(64, '0'); + } else if (type == 'bool') { + final isTrue = (param is bool) ? param : param.toString().toLowerCase() == 'true'; + return (isTrue ? '1' : '0').padLeft(64, '0');
18-33: Non-compliant ABI encoding for dynamic and numeric types; prefer a proven encoderThe current encodeParameter implementation is not standards-compliant for ABI v2:
- Strings require length-prefix + 32-byte alignment and offset handling.
- Addresses/ints/bools should be strictly 32-byte big-endian words; that’s partially handled, but without full tuple/array coverage.
- No support for arrays, bytes, or nested tuples.
Use a battle-tested encoder (e.g., web3dart’s ABI encoder) to avoid subtle bugs during contract calls.
Here’s a directional example outside the selected range, using web3dart types for correctness:
import 'package:web3dart/web3dart.dart'; // Example usage: final encoded = bytesToHex( const AbiType.function('transfer(address,uint256)') .encodeCall([EthereumAddress.fromHex(to), BigInt.parse(amountWei)]), include0x: true, );If keeping a custom encoder, add comprehensive unit tests for: address, uint256, int256 (negative), bool, string (unicode), bytesN, bytes, arrays, and tuples.
I can help replace the custom encoder with web3dart across call sites. Want a targeted PR patch?
lib/utils/services/ipfs_services.dart (2)
9-31: Ensure upload state resets on all paths; add try/finally and improve error handlingCurrently,
setUploadingState(false)won’t run if the request throws, potentially leaving the UI stuck in “uploading” state. Also, error responses are discarded. Recommend adding try/catch/finally, typing the callback precisely, and logging the error body.Apply this diff:
-Future<String?> uploadToIPFS( - File imageFile, Function(bool) setUploadingState) async { - setUploadingState(true); - - var url = Uri.parse("https://api.pinata.cloud/pinning/pinFileToIPFS"); - var request = http.MultipartRequest("POST", url); - request.headers.addAll({ - "pinata_api_key": API_KEY, - "pinata_secret_api_key": API_SECRET, - }); - - request.files.add(await http.MultipartFile.fromPath("file", imageFile.path)); - var response = await request.send(); - - setUploadingState(false); - - if (response.statusCode == 200) { - var jsonResponse = json.decode(await response.stream.bytesToString()); - return "https://gateway.pinata.cloud/ipfs/${jsonResponse['IpfsHash']}"; - } else { - return null; - } -} +Future<String?> uploadToIPFS( + File imageFile, void Function(bool) setUploadingState) async { + setUploadingState(true); + try { + final url = Uri.parse("https://api.pinata.cloud/pinning/pinFileToIPFS"); + final request = http.MultipartRequest("POST", url) + ..headers.addAll({ + "pinata_api_key": API_KEY, + "pinata_secret_api_key": API_SECRET, + }) + ..files.add(await http.MultipartFile.fromPath("file", imageFile.path)); + + final response = await request.send(); + final body = await response.stream.bytesToString(); + + if (response.statusCode == 200) { + final jsonResponse = json.decode(body); + return "https://gateway.pinata.cloud/ipfs/${jsonResponse['IpfsHash']}"; + } else { + debugPrint("IPFS upload failed [${response.statusCode}]: $body"); + return null; + } + } catch (e, st) { + debugPrint("IPFS upload exception: $e"); + return null; + } finally { + setUploadingState(false); + } +}Additionally add this import (outside the selected range):
import 'package:flutter/foundation.dart';
15-18: Critical: Do not ship Pinata API secret in client appsIncluding
pinata_secret_api_keyin a mobile app is a credential leak risk. Anyone can extract it and abuse your Pinata account. Move the upload behind a backend (server/serverless) that holds the secret or issue short-lived, scoped tokens server-side.If you choose to use server-issued short-lived JWTs for Pinata, headers could look like this (and the function accept a token, not a secret):
-Future<String?> uploadToIPFS( - File imageFile, void Function(bool) setUploadingState) async { +Future<String?> uploadToIPFS( + File imageFile, void Function(bool) setUploadingState, {required String pinataJwt}) async { ... - request.headers.addAll({ - "pinata_api_key": API_KEY, - "pinata_secret_api_key": API_SECRET, - }); + request.headers.addAll({ + "Authorization": "Bearer $pinataJwt", + }); ...I can help sketch a minimal backend proxy (Cloud Functions/Edge) if needed.
lib/providers/mint_nft_provider.dart (1)
63-72: clearData() method missing _details field.The
clearData()method clears most fields but doesn't reset_detailsand_detailsHash. This could lead to stale data persisting between minting sessions.void clearData() { _latitude = 0; _longitude = 0; _species = ""; + _details = ""; + _detailsHash = ""; _imageUri = ""; _qrIpfsHash = ""; _geoHash = ""; _initialPhotos.clear(); notifyListeners(); }lib/pages/mint_nft/mint_nft_details.dart (2)
22-32: Fix validation logic - description field removed from UI.The validation still checks for both description and species, but the description field appears to have been removed from the UI. This will cause validation to always fail since
descriptionController.textwill be empty.- if (description.isEmpty || species.isEmpty) { - _showCustomSnackBar( - "Please enter both description and species.", - isError: true, - ); - return; - } + if (species.isEmpty) { + _showCustomSnackBar( + "Please enter the tree species.", + isError: true, + ); + return; + }Alternatively, if the description field should remain, add it back to the UI form.
190-197: Remove description form field or update validation.This form field for description is inconsistent with the validation logic that suggests the description field was removed. Either remove this field or update the validation logic to include it.
If keeping the description field:
_buildFormField( controller: speciesController, label: 'Tree Species', hint: 'e.g., Oak, Pine, Maple...', icon: Icons.eco, maxLines: 1, ), +const SizedBox(height: 20), +_buildFormField( + controller: descriptionController, + label: 'Description', + hint: 'Describe your tree planting experience...', + icon: Icons.description, + maxLines: 5, + minLines: 3, +),If removing the description field, delete lines 190-197 and update the validation logic as suggested in the previous comment.

color: Colors.whitebut its container background is also white, making the icon invisible.decoration: BoxDecoration( color: Colors.white, borderRadius: BorderRadius.circular(14), ), child: const Icon( Icons.location_on, - color: Colors.white, + color: Color(0xFF1CD381), size: 28, ),
564-567: Icon color doesn't match its background in coordinate field.The icon has the same color as its container background, making it invisible.
child: Icon( icon, - color: const Color(0xFF1CD381), + color: Colors.white, size: 14, ),lib/providers/wallet_provider.dart (2)
257-257: Remove incorrect getter implementationThe
userAddressgetter returns null instead of returning the actual_currentAddressvalue.- get userAddress => null; + String? get userAddress => _currentAddress;
392-392: Reference to undefined variableThe
switchChainmethod referenceschainInfo['name']but should use_chainInfo[newChainId]['name'].- _updateStatus('Switching to ${chainInfo['name']}...'); + _updateStatus('Switching to ${_chainInfo[newChainId]?['name'] ?? 'Unknown Chain'}...');
🧹 Nitpick comments (24)
lib/utils/services/get_current_location.dart (2)
10-12: Include error type in LocationException.toString for better diagnosticsHelps distinguish failure modes in logs and crash reports.
- @override - String toString() => 'LocationException: $message'; + @override + String toString() => 'LocationException($type): $message';
136-140: Optionally filter invalid updates in the location streamIf consumers commonly require valid coordinates only, filter them here to reduce downstream checks. Safe and low-cost.
- Stream<LocationInfo> getLocationStream() { - return _location.onLocationChanged.map((locationData) { - return LocationInfo.fromLocationData(locationData); - }); - } + Stream<LocationInfo> getLocationStream() { + return _location.onLocationChanged + .map(LocationInfo.fromLocationData) + .where((loc) => loc.isValid); + }lib/providers/theme_provider.dart (1)
45-61: Optional: handle persistence errors and consider awaiting saves in controlled flowscurrent behavior is fine for UI responsiveness, but persisting theme mode without error handling can silently fail. Wrap SharedPreferences I/O in try/catch and optionally await in flows where you can afford it (e.g., settings screen “Apply” action).
Here’s a minimal, non-blocking improvement:
- Future<void> _saveThemePreference() async { - final prefs = await SharedPreferences.getInstance(); - String themeModeString; + Future<void> _saveThemePreference() async { + try { + final prefs = await SharedPreferences.getInstance(); + String themeModeString; // ... - await prefs.setString('theme_mode', themeModeString); + await prefs.setString('theme_mode', themeModeString); + } catch (e) { + // Optionally add logging + debugPrint('Failed to save theme preference: $e'); + } }lib/models/wallet_chain_option.dart (1)
32-35: Deduplicate RPC URL sources to prevent drift
rpcUrlsandchainInfoList[..]['rpcUrl']duplicate the same data. Prefer a single source (chainInfoList) and derive a lookup helper to avoid config drift.One approach:
-final Map<String, String> rpcUrls = { - '11155111': 'https://eth-sepolia.g.alchemy.com/v2/$ALCHEMY_API_KEY', - '1': 'https://eth-mainnet.g.alchemy.com/v2/$ALCHEMY_API_KEY', -}; +String? rpcUrlFor(String chainId) => + chainInfoList[chainId]?['rpcUrl'] as String?;Follow-up: update call sites to use
rpcUrlFor(chainId).Also applies to: 37-58
lib/widgets/nft_display_utils/tree_NFT_view_widget.dart (1)
63-67: Remove unused helper after switching to widget-managed truncationOnce the Text widget handles truncation, this helper becomes dead code.
-String _formatDescription(String description) { - return description.length > 80 - ? '${description.substring(0, 80)}...' - : description; -} +// Removed: truncation is now handled by Text's maxLines/overflow.lib/main.dart (2)
27-35: Ensure Flutter binding is initialized before async setupWhile dotenv typically doesn't require it, initializing the binding preempts issues if future initializations depend on platform channels.
void main() async { + WidgetsFlutterBinding.ensureInitialized(); try { await dotenv.load(fileName: ".env"); } catch (e) { logger.d("No .env file found or error loading it: $e"); }
26-26:NavigationService.navigatorKeyis defined but not usedIf you intend to navigate without context, wire this key into GoRouter; otherwise, remove the dead code.
Example (verify property name for your go_router version):
final GoRouter router = GoRouter( navigatorKey: NavigationService.navigatorKey, initialLocation: RouteConstants.homePath, routes: [ /* ... */ ], );lib/utils/services/switch_chain_utils.dart (3)
13-61: Prevent bottom sheet overflow with long chain listsIf many chains are supported, the current Column may overflow. Wrap with a scroll view.
- child: Column( + child: SingleChildScrollView( + child: Column( mainAxisSize: MainAxisSize.min, crossAxisAlignment: CrossAxisAlignment.start, children: [ @@ - const SizedBox(height: 16), - ], - ), + const SizedBox(height: 16), + ], + ), + ),
41-46: Align selection colors with theme instead of hard-coded greensImproves dark-mode support and overall theming consistency.
- tileColor: isCurrentChain ? Colors.green[50] : null, + tileColor: isCurrentChain + ? Theme.of(context) + .colorScheme + .primaryContainer + .withOpacity(0.2) + : null, shape: RoundedRectangleBorder( borderRadius: BorderRadius.circular(8), side: BorderSide( - color: isCurrentChain ? Colors.green : Colors.grey[300]!, + color: isCurrentChain + ? Theme.of(context).colorScheme.primary + : Theme.of(context).dividerColor, ), ),
25-37: Prefer a typed model for chains overMapto reduce runtime risksUsing
Mapwith string keys and casts increases the chance of runtime errors. Consider a simpleChainInfoclass and returnList<ChainInfo>from the provider.If helpful, I can draft a minimal
ChainInfomodel and update the provider and widget usage.lib/widgets/nft_display_utils/tree_nft_view_details_with_map.dart (1)
108-122: Consider extracting the image display logic into a separate method.The ListView.builder for displaying images could be extracted into a separate method to improve code organization and readability.
+ Widget _buildImagesList(MintNftProvider provider) { + return ListView.builder( + shrinkWrap: true, + physics: const NeverScrollableScrollPhysics(), + itemCount: provider.getInitialPhotos().length, + itemBuilder: (context, index) { + return Padding( + padding: const EdgeInsets.symmetric(vertical: 4.0), + child: Image.network( + provider.getInitialPhotos()[index], + height: 100, + width: double.infinity, + fit: BoxFit.cover, + ), + ); + }, + ); + }Then replace the ListView.builder block with:
- ListView.builder( - shrinkWrap: true, - physics: const NeverScrollableScrollPhysics(), - itemCount: provider.getInitialPhotos().length, - itemBuilder: (context, index) { - return Padding( - padding: const EdgeInsets.symmetric(vertical: 4.0), - child: Image.network( - provider.getInitialPhotos()[index], - height: 100, - width: double.infinity, - fit: BoxFit.cover, - ), - ); - }), + _buildImagesList(provider),lib/pages/tree_details_page.dart (1)
12-14: Consider adding proper styling and layout.The current implementation uses basic styling. Consider enhancing the UI with proper styling, loading states, and error handling for a production-ready tree details page.
body: Center( - child: Text('Showing details for tree ID: $treeId'), + child: Padding( + padding: const EdgeInsets.all(16.0), + child: Column( + mainAxisAlignment: MainAxisAlignment.center, + children: [ + Card( + child: Padding( + padding: const EdgeInsets.all(24.0), + child: Column( + children: [ + Icon( + Icons.park, + size: 64, + color: Colors.green, + ), + const SizedBox(height: 16), + Text( + 'Tree ID: $treeId', + style: Theme.of(context).textTheme.headlineSmall, + ), + const SizedBox(height: 8), + Text( + 'Tree details will be implemented here', + style: Theme.of(context).textTheme.bodyMedium, + ), + ], + ), + ), + ), + ], + ), + ), ),lib/components/universal_navbar.dart (1)
104-131: Consider removing commented code completely.The theme toggle functionality is commented out but the code remains. Consider removing it entirely to reduce code clutter, or provide a clear reason for keeping it commented.
- // Container( - // width: 36, - // height: 36, - // decoration: BoxDecoration( - // color: Colors.white.withOpacity(0.2), - // borderRadius: BorderRadius.circular(8), - // border: Border.all( - // color: Colors.white.withOpacity(0.3), - // width: 1, - // ), - // ), - // child: IconButton( - // padding: EdgeInsets.zero, - // icon: Icon( - // themeProvider.isDarkMode - // ? Icons.light_mode - // : Icons.dark_mode, - // color: Colors.white, - // size: 18, - // ), - // onPressed: () { - // themeProvider.toggleTheme(); - // }, - // tooltip: themeProvider.isDarkMode - // ? 'Switch to Light Mode' - // : 'Switch to Dark Mode', - // ), - // ),lib/pages/home_page.dart (1)
26-33: Consider adding responsive width constraints for better mobile experience.The fixed widths (400px) may not work well on smaller mobile devices. Consider using responsive sizing that adapts to screen width.
- SizedBox(width: 400, child: ProfileSectionWidget()), - SizedBox( - width: 400, - height: 600, - child: UserNftsWidget( - isOwnerCalling: true, - userAddress: walletProvider.currentAddress ?? ''), - ), + SizedBox( + width: MediaQuery.of(context).size.width.clamp(300.0, 400.0), + child: ProfileSectionWidget(), + ), + SizedBox( + width: MediaQuery.of(context).size.width.clamp(300.0, 400.0), + height: 600, + child: UserNftsWidget( + isOwnerCalling: true, + userAddress: walletProvider.currentAddress ?? ''), + ),lib/pages/register_user_page.dart (1)
125-129: Null check is redundant for non-nullable String field.The field
_profilePhotoHashis declared asString?with an initial value of"". The null check on line 125 is redundant since you're checking for empty string on the same line.- if (_profilePhotoHash == null || _profilePhotoHash!.isEmpty) { + if (_profilePhotoHash?.isEmpty ?? true) {lib/utils/services/contract_write_functions.dart (1)
130-130: Fix typo in log message.There's a typo in "registeration" - it should be "registration".
- logger.i("User registeration transaction sent: $txHash"); + logger.i("User registration transaction sent: $txHash");lib/utils/services/contract_read_services.dart (2)
84-86: Improve null-safe data extractionThe current nested ternary operators are hard to read and potentially error-prone. Consider a cleaner approach.
- final trees = result.length > 0 ? result[0] ?? [] : []; - final totalCount = - result.length > 1 ? int.parse(result[1].toString()) : 0; + final trees = result.isNotEmpty ? (result[0] ?? []) : []; + final totalCount = result.length > 1 + ? int.tryParse(result[1]?.toString() ?? '0') ?? 0 + : 0;
180-181: Consistent data extraction patternApply the same improved null-safe extraction pattern used earlier.
- final profile = result.length > 0 ? result[0] ?? [] : []; + final profile = result.isNotEmpty ? (result[0] ?? []) : [];lib/widgets/nft_display_utils/user_nfts_widget.dart (3)
49-50: Missing debug print messageThe error message references "Tree data" but this is for parsing Tree model, not profile data.
- debugPrint("Error parsing Tree data: $e"); + debugPrint("Error parsing Tree data: $e");
325-326: Implement map navigation functionalityThe "View on the map" button currently has an empty onPressed handler.
Would you like me to help implement the map navigation functionality or create an issue to track this TODO?
103-111: Add documentation for public widget parametersConsider adding documentation to explain the purpose of
isOwnerCallingand when it should be true/false.class UserNftsWidget extends StatefulWidget { + /// Whether the current user is viewing their own NFTs final bool isOwnerCalling; + /// The wallet address of the user whose NFTs to display final String userAddress;lib/widgets/profile_widgets/profile_section_widget.dart (2)
148-148: Typo in error messageMissing space between "Error" and "loading".
- _errorMessage = 'Errorloading User profile details: $e'; + _errorMessage = 'Error loading User profile details: $e';
84-84: Unnecessary empty string initializationThe
_errorMessageis initialized to an empty string but should be null initially since it's checked for null elsewhere.- String? _errorMessage = ""; + String? _errorMessage;lib/providers/wallet_provider.dart (1)
24-25: Remove commented-out codeThe commented code for reading the chain ID from environment should be removed if it's no longer needed.
static final String _correctChainId = "11155111"; - // dotenv.env['APPLICATION_CHAIN_ID'].toString();

lib/utils/services/get_current_location.dart (4)
76-86: Service disabled flow is solidGood user-friendly flow: check service, attempt enable, then fail fast with a typed error and log.
101-106: Validation of coordinates is correctCatching null lat/lng and surfacing a specific error type is appropriate.
21-53: LocationInfo model + factory look goodWell-scoped data holder, clean factory mapping (including time), a helpful formattedLocation, and an isValid guard. No issues.
Also applies to: 60-66
142-153: Availability check is pragmaticSimple and effective: service must be enabled and permission granted; logs on exceptions. LGTM.

lib/utils/constants/contract_abis/tree_nft_contract_abi.dart (3)
692-695: Confirm ABI field name matches Solidity contractThe ABI at lib/utils/constants/contract_abis/tree_nft_contract_abi.dart:692 declares the parameter
"visiblecount"(lower-case “c”). A project-wide search found no references tovisibleCountin your Dart code.
Please verify the field’s exact name in your Solidity contract:
- If the contract uses
visibleCount(camelCase), update the ABI JSON to"name": "visibleCount"to ensure proper decoding.- If the contract indeed defines
visiblecount, no change is needed.
84-161: No remaining tuple-index mappings to updateAll index-based decodings against the updated Tree struct have been adjusted:
- In lib/widgets/nft_display_utils/user_nfts_widget.dart, id (at [0]) and metadata (at [8]) now align with the ABI’s new field order.
- Other numeric
[...]usages either handle the two-element return of paginated calls or occur in unrelated list indexing.No further changes are needed.
381-485: No consumers of getRecentTreesPaginated found
I searched the entire Dart codebase and did not find any calls togetRecentTreesPaginatedor parsing of a returnedhasMorefield. Until you add a service wrapper (e.g. inContractReadFunctions) and begin consuming this new ABI function, there’s no client‐side pagination logic to update.Likely an incorrect or invalid review comment.

In lib/components/bottom_navigation_widget.dart around line 29, the
backgroundColor is hard-coded to Color.fromARGB(...) which breaks dark-mode and
accessibility; change it to use the theme (e.g.,
Theme.of(context).colorScheme.primary or colorScheme.surface/primaryContainer
depending on intent) so the color adapts to light/dark themes and respects
contrast; ensure this widget has access to BuildContext (use the build(context)
parameter) and replace the literal with
Theme.of(context).colorScheme.<chosenToken> (optionally with .withOpacity(...)
or use Theme.of(context).colorScheme.on<ChosenToken> for text/icon contrast) so
colors follow the app theme and improve accessibility.

Use route constants and consistent naming for the Register User route
Avoid hard-coded strings and adopt constants for both path and name. This also makes refactors safer.
