Shortcut for removing widgets

[dennis-g]

In HTML there is a shortcut for “Unwrap/Remove...” for removing HTML tags. This would be a really useful feature for removing widgets in Flutter. Instead of using the option “Remove this widget” in the context actions dialog.

It would probably take more discussion to have something like this in the plugin by default. Would it be practical to add a shortcut you'd like to use in your own system?
