使用metamask在颤音中签署消息

Question

我正在使用 walletconnect_dart 包装将我的flutter应用程序连接到MetAmask。但是我希望用户在metAmask中签署一条消息并获得签名。我该怎么做颤动？

Answer 1

这是您的解决方案

  ElevatedButton signMessage() {
return ElevatedButton(
    onPressed: () async {
      String? signmessage = "Sign Message";
      List<String?> params = [signmessage, walletAddress];
      String method = "personal_sign";

      await launchUrl(Uri.parse(walletConnect.session.toUri()),
          mode: LaunchMode.externalApplication);
     final _signature = await walletConnect.sendCustomRequest(
        method: method,
        params: params,
      );

      print( _signature); 
    },
    child: const Text("SIGN MESSAGE"));}
