Dart SDK for TON Connect

Improved Dart SDK for TON Connect 2.0

Here is the fork of DartTonConnect package. Forked version advantages:

1. Stream with TON HTTP network events
2. Transaction sending interface with payload support
3. Bug fixes

Install

With Dart:

 $ dart pub add darttonconnect_plus

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

dependencies:
  darttonconnect_plus: ^1.0.1

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

Configure

Create JSON-manifest file with your app description. This info will be displayed inside the wallet during the connection procedure.

{
  "url": "<app-url>",                        // required
  "name": "<app-name>",                      // required
  "iconUrl": "<app-icon-url>",               // required
  "termsOfUseUrl": "<terms-of-use-url>",     // optional
  "privacyPolicyUrl": "<privacy-policy-url>" // optional
}

This file must be available to GET by its URL.

Init

Pass manifest to TonConnectManager

var tonManager = TonConnectManager(
'https://gist.githubusercontent.com/romanovichim/e81d599a6f3798bb9f74ab1970a8b376/raw/43e00b0abc824ef272ac6d0f8083d21456602adf/gistfiletest.txt');

Subscribe to TON events stream messages

    tonManager.messagesStream.listen((TonPaymentStatus status) {
      
    });
