### Fetch Supported Wallets List with TonConnect

Source: https://github.com/romanovichim/darttonconnect/blob/main/README.md

Example of initializing the TonConnect connector and asynchronously fetching a list of all supported wallets. The `connector.getWallets()` method retrieves available wallet applications, which can then be displayed to the user.

```Dart
import 'package:darttonconnect/ton_connect.dart';

Future<void> main() async {
  final connector = TonConnect('https://raw.githubusercontent.com/XaBbl4/pytonconnect/main/pytonconnect-manifest.json');
  final List<WalletApp> wallets = await connector.getWallets();
  print('Wallets: $wallets');
}
```

### Initialize Wallet Connection with Dart TonConnect

Source: https://github.com/romanovichim/darttonconnect/blob/main/README.md

Demonstrates how to initiate a wallet connection using a universal link with the `darttonconnect` library. The generated URL should be presented to the user as a QR code or deep link for approval, and the console will update upon user approval.

```Dart
import 'package:darttonconnect/ton_connect.dart';

final generatedUrl = await connector.connect(wallets.first);
print('Generated url: $generatedUrl');
}
```

--------------------------------

### Import Darttonconnect Modules

Source: https://github.com/romanovichim/darttonconnect/blob/main/README.md

Essential import statements for various modules within the darttonconnect SDK. These imports provide access to core functionalities like crypto, exceptions, parsers, providers, storage, and the main TonConnect class.

```Dart
import 'package:darttonconnect/crypto/session_crypto.dart';

### Send Toncoin Transaction with Dart TonConnect

Source: https://github.com/romanovichim/darttonconnect/blob/main/README.md

Illustrates how to construct and send a transaction using the `darttonconnect` library. It includes a basic transaction object structure with `validUntil` and `messages` fields, and provides error handling for user rejections or other unexpected issues during the transaction process.

```Dart
const transaction = {
  "validUntil": 1718097354,
  "messages": [
    {
      "address":
          "0:575af9fc97311a11f423a1926e7fa17a93565babfd65fe39d2e58b8ccb38c911",
      "amount": "20000000"
    }
  ]
};

try {
  await connector.sendTransaction(transaction);
} catch (e) {
  if (e is UserRejectsError) {
    logger.d(
        'You rejected the transaction. Please confirm it to send to the blockchain');
  } else {
    logger.d('Unknown error happened $e');
  }
}
```

--------------------------------

### Define TonConnect Manifest JSON

Source: https://github.com/romanovichim/darttonconnect/blob/main/README.md

JSON structure for the `tonconnect-manifest.json` file, which is required for the app to pass meta information to the wallet. It includes essential fields like `url`, `name`, and `iconUrl`, along with optional fields for terms of use and privacy policy URLs.

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

--------------------------------

### Subscribe to TonConnect Status Changes

Source: https://github.com/romanovichim/darttonconnect/blob/main/README.md

Shows how to subscribe to connection status changes using `connector.onStatusChange()`. This allows the application to react to updates in the wallet connection state, such as a wallet connecting or disconnecting, and update the UI accordingly.

```Dart
/// Update state/reactive variables to show updates in the ui.
void statusChanged(dynamic walletInfo) {
  print('Wallet info: $ walletInfo');
}

connector.onStatusChange(statusChanged);
```

--------------------------------

### Disconnect from Wallet with Dart TonConnect

Source: https://github.com/romanovichim/darttonconnect/blob/main/README.md

Shows how to disconnect an active wallet session using the `disconnect` method provided by the `darttonconnect` library, effectively ending the connection.

```Dart
connector.disconnect();
```

--------------------------------

### Restore TonConnect Connection in Flutter

Source: https://github.com/romanovichim/darttonconnect/blob/main/README.md

Demonstrates how to restore a previously established TonConnect connection when the application or page reloads. This is typically done by calling `connector.restoreConnection()` within a Flutter widget's `initState` or a similar lifecycle method, ensuring a seamless user experience.

```Dart
import 'package:darttonconnect/ton_connect.dart';

@override
void initState() {
  // Override default initState method to call restoreConnection
  // method after screen reloading.
  super.initState();
  WidgetsBinding.instance.addPostFrameCallback((_) {
    if (!connector.connected) {
      restoreConnection();
    }
  });
}


/// Restore connection from memory.
void restoreConnection() {
  connector.restoreConnection();
}
```
