TON CLIENT DART

It is Dart packege that provide binding to TON SDK Client library. TON SDK (TONOS Client Library) is a library written in Rust that can be dynamically linked. It provides all heavy-computation components and functions, such as TON Virtual Machine, TON Transaction Executor, ABI-related functions, boc-related functions, crypto functions.

Use this package as a library

1. Depend on it

Add this to your package's pubspec.yaml file:

dependencies:
  ton_client_dart: ^0.1.2

2. Install it

You can install packages from the command line:

  $ pub get

Alternatively, your editor might support pub get. Check the docs for your editor to learn more.

3. Import it

Now in your Dart code, you can use:

  import 'package:ton_client_dart/ton_client_dart.dart'

How to use

Configuring client

import 'package:ton_client_dart/ton_client_dart.dart'
//..
var CLIENT_DEFAULT_SETUP = {
  'network': {
    'server_address': 'http://localhost',
    'message_retries_count': 5,
    'message_processing_timeout': 40000,
    'wait_for_timeout': 40000,
    'out_of_sync_threshold': 15000,
    'access_key': ''
  },
  'crypto': {'fish_param': ''},
  'abi': {
    'message_expiration_timeout': 40000,
    'message_expiration_timeout_grow_factor': 1.5
  }
};
//..
var client = TonClient();
await client.connect(CLIENT_SETUP);
//..
await client.disconnect();

To initialize the client, you need to call the TonClient.connect function and pass the settings to it. After you have finished working with the client, you must close it with the TonClient.disconnect function. Don't forget to call this functions.

Output TON SDK version

  await client.connect(CLIENT_DEFAULT_SETUP);
  //..
  var result = await client.version();
  print(result.version);
  //..
  await client.disconnect();

Query collection

//..
  var query = await client.net.query_collection(ParamsOfQueryCollection(
      collection: 'accounts',
      result: 'id code',
      filter: {
        'id': {'eq': enmsg.address}
  }));
//..

Query top 3 richest accounts

//..
  var pq = ParamsOfQueryCollection(
      collection: 'accounts',
      result: 'id balance',
      limit: 3,
      order: [OrderBy(path: 'balance', direction: SortDirection.DESC())]
  );
//..

Execute getmethod and returns data from TVM stack

//..
   final code = await File('./test/files/run_get_code.txt').readAsString();
   final data = await File('./test/files/run_get_data.txt').readAsString();

   final res = await client.abi.encode_account(ParamsOfEncodeAccount(
    state_init: StateInitSource_StateInit(code: code, data: data)));

   final adr = await client.utils.convert_address(ParamsOfConvertAddress(
    address: res.id, output_format: AddressStringFormat_Hex()));

   var res_run_get = await client.tvm.run_get(ParamsOfRunGet(
    account: res.account, function_name: 'participant_list'));
   String result = res_run_get.output.toString();
//..
