Flutter news app, that show cases the following: SQflite,HTTP operations, caching responses, user preferences, clean architecture and tests.
- Flutter -is a mobile cross-platform,UI toolkit.
- Cubit - The Cubit is a subset of the famous implementation of BLoC Pattern: bloclibrary.dev, it abandons the concept of Events and simplifies the way of emitting states.
- Shared preferences - for storing key based values.
- sqflite -sqlite db plugin for android, ios and macos.
Decide on the state management: flutter_cubitResearch on a news app design from (dribbble, uplabs .. etc)Add HTTP layerAdd DB layer- Finally add test
-
- cubit: holds all the cubits
- model: holds the model classes
- pages: ui residence
- Repository divided into two the http repo for all http calls and db repo for local database operations
- Util: for utilities used in the app

Heavily used in the app, singleton pattern is a software design pattern that restricts the instantiation of a class to one "single" instance. example:
class HttpClient { // Setup a singleton static final HttpClient _httpClient = HttpClient._internal(); factory HttpClient() { return _httpClient; } HttpClient._internal(); static String baseUrl(String subEndpoint) => "http://newsapi.org/v2/$subEndpoint&apiKey=API KEY"; Future<http.Response> getRequest(String endpoint) async { try { http.Response response = await http.Client().get( baseUrl(endpoint), ); debugPrint("getRequest:\nurl:$endpoint\nresponse:\n$response"); return response; } catch (e) { debugPrint(e); throw e; } } }
