Pass Parameter to channel.invokeMethod

[rubFlutter]

Hi all,

I'm using the `window_size` and I'm stuck on how to pass parameters

(https://github.com/google/flutter-desktop-embedding/tree/master/plugins/window_size)

This is my code:

await channel.invokeMethod('setWindowFrame');

If you want to learn how invokeMethod works, the MethodChannel API docs or any of the many articles about Flutter plugin development would be the best place to start; nothing about the Dart side is desktop-specific.

If you want examples of using the window_size channel in particular, the implementation of the plugin's Dart API is right there. But that raises the real question: why are you trying to call the method channel directly instead of using the API?

My mistake, I found out how to use this plugin (I hope)

Is this correct?

  setWindowTitle('My App Title');
  final ret = await getWindowInfo();
  print(ret.frame.width.toString());
  setWindowMaxSize(Size(800, 600)); <-- ERROR

By the way, why Am I getting this error in the line above?

Minimum and maximum size aren't implemented for Windows yet; see https://github.com/google/flutter-desktop-embedding/issues/483.
