[Feature Request] Adding Flutter Widget Previewer.

[Kiruel]

As part of Flutter version 3.38 Flutter introduces widget preview:
https://docs.flutter.dev/tools/widget-previewer

Could we have a way to integrate this into this package?

Using:
flutter widget-preview start allows us to start this preview.

Maybe we could add a new command:
FlutterWidgetPreviewStart
