Grid layout API isn't always quite efficient to responsively position elements.

Describe the solution you'd like

Having a Layout inspired of the HTML5 flexbox would be refreshing and efficient for a lot of responsive positioning situations.

MAUI has done it : https://docs.microsoft.com/en-us/dotnet/maui/user-interface/layouts/flexlayout

So the API and the logic could potentially by ported.
