Get Method Call arguments in flutter window

Question

Does anyone know how to get an argument pass by MethodChannel in windows? Here is my code to send and receive data. I need to get data value in string type

String data = "Some data";
await platform.invokeMethod("OpenViewer", {"data":data});

channel->SetMethodCallHandler([](const flutter::MethodCall<>& call, std::unique_ptr<flutter::MethodResult<>> result)
        {
            // check method name called from dart
            if (call.method_name().compare("OpenViewer") == 0) {
                
            }
            else {
                result->NotImplemented();
            }
        });

Solution

you could use something like below

 if (method_call.method_name().compare("launch") == 0) {
    std::string url = GetUrlArgument(method_call);
    if (url.empty()) {
      result->Error("argument_error", "No URL provided");
      return;
    }

    std::optional<std::string> error = LaunchUrl(url);
    if (error) {
      result->Error("open_error", error.value());
      return;
    }
    result->Success(EncodableValue(true));
