Code Review
This pull request adds documentation for migrating to the standalone material_ui and cupertino_ui packages, which decouple Flutter's design systems from the core SDK. The documentation covers automated and manual migration steps, the compatibility bridge, and localization changes. Feedback on the documentation suggests improving the code example for the compatibility bridge by safely handling a potentially null child widget instead of using a force-unwrap operator, which could lead to runtime exceptions.

Do you mean beyond what is already here? This should cover it. |
Adds the migration guide for migrating to material_ui and cupertino_ui I believe we'll be adding more docs, or a dedicated page on the site, but it would be great to have a place to point for now that isn't just the latest the release blog. :) We'll be making a bigger call to action to migrate in the Fall release after we deprecate the original libraries. This should be good in the meantime for our early adopters. I already incorporated the early feedback we have received from them.
