Support auto widgets

[XyrelTenz]

Add auto widgets please similar to vscode the question mark on left side can add or suggest widget to add because it's really convention for developer like me when adding a parent widget so you dont need to refactory it.

E.G when adding Row you manually wrap the child or change it to children: []

also is it bug or not the color visualization only works on Colors and Color but when using theme.of(context) it not visualize
