Describe the bug
"wrap with widget" wraps the entire switch expression instead of the current branch

To Reproduce

enum MyEnum {a, b}
class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return switch(get()) {
        MyEnum.a =>  const Text('a'),
        MyEnum.b =>  const Text('b'),
    };
  }
}
MyEnum get() {
// ...
}

Move your cursor to Text('a') and do a "Wrap with widget..." (or anything else)

Expected behavior
The new widget should be parent of the Text('a') branch and not of the entire switch expression
