connect method
Generates universal link for an external wallet and subscribes to the wallet's bridge, or sends connect request to the injected wallet.
Implementation
Future<String> connect(WalletApp wallet, [dynamic request]) async {
if (connected) {
throw WalletAlreadyConnectedError(null);
}
if (provider != null) {
provider!.closeConnection();
}
provider = _createProvider(wallet);
return await provider!.connect(_createConnectRequest(request));
}
