I updated from Dart 3.0 to 3.2 and I am getting some execution errors. Original code using window that worked up to 3.0.5: Before

Tried to change to use View class to work with 3.19.0 and over: After

I am getting: Unhandled Exception: type '_ReusableRenderView' is not a subtype of type '_ExposedRenderView' in type cast

The following asserting was thrown: The render object for SizedBox cannot find ancestor render object to attach to. The ownership chain for the RenderObject in question was: SizedBox ← [root]

Try wrapping your widget in a View widget or any other widget that is backed by a RenderTreeRootElement to serve as the root of the render tree.

My problem is very close to:https://github.com/flutter/flutter/issues/141009

Resume: I need to replace window component to create a RenderView, but it looks like View works fine when you have a Tree/Widget component binding to your mobile root tree app, when I am using a Windows one.
