如何使用method通道将自定义POJO或DTO对象从flutter传递到Android？

const platform = MethodChannel('com.example.channel');
platform.setMethodCallHandler((MethodCall call) async {
  if (call.method == 'receiveData') {
    // 处理接收到的数据
    Map<String, dynamic> data = call.arguments;
    // 进行相应的操作
  }
});

MethodChannel channel = new MethodChannel(getFlutterView(), "com.example.channel");
channel.invokeMethod("receiveData", yourCustomObject);

Future<void> sendDataToAndroid(Map<String, dynamic> data) async {
  const platform = MethodChannel('com.example.channel');
  await platform.invokeMethod('sendData', data);
}
