Dart-code: Refactoring - Move Widget/Class to New File

[skybur]

I don't know if this is VSCode feature request or specifically for dart/flutter, but is it possible to move a widget class (or any other class) to a new file? If I remember correctly Visual Studio have this refactoring option.

Say I have this my_widget.dart file.

class MyWidget extends StatelessWidget {
  const MyWidget({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Container(
      child: child,
    );
  }
}

class MyOtherWidget extends StatelessWidget {
  const MyOtherWidget({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Container(
      child: child,
    );
  }
}

I want to move MyOtherWidget to my_other_widget.dart (automatically created) and automatically import that file if my_widget.dart contains MyOtherWidget references. Sorry if this is a duplicate.
Thank you.

This requires support in the SDK's analysis server before it can be supported here. There's an open issue for it you can 👍 and subscribe to at https://github.com/dart-lang/sdk/issues/30310.

If it's added to the server, then it could be exposed here in VS Code.

Wow that issue is almost 2 years old 😅

[DanTup]

Yeah, it only has 3 👍's including yours. I don't think it's in huge demand (probably mostly because people tend to put many classes per file).

Well 11👍 now ;)
I really wish to have way more refactorings for dart and this is one that I would honestly use very often.

12+ now :) Refactoring is all we need to be code boy scouts. Any news on this feature @DanTup ?

[DanTup]

This would first need to be implemented in the analyzer in the SDK (https://github.com/dart-lang/sdk/issues/30310). Once implemented there, it would be available to both VS Code and IntelliJ/Android Studio extensions to expose in the UI.

Now there are 66, will there be any updates now?

[DanTup]

As mentioned above, this can't be implemented here until it's available in the server. There was a response posted on the SDK issue last month:
