Migrate example, tests, and benchmarks away from 'pkg:flutter/material.dart' #2258

What do you want implemented?

The example app, and probably also the tests and benchmarks, can probably be migrated to material_ui.

Note the concerns in the parent issue #2255:

Ideally, we keep the library as backward-supporting as possible. The example app could be updated to use Flutter 3.44 or above, but we currently build the example app in our CI/CD pipelines to ensure that the library can be build on Flutter 3.27. It's possible this is OK if we can rely on the tests to still prove support for the minimum supported version.

Although once we're at the point of migrating to material_ui then it might be time to just drop support for older versions of Flutter anyway.

What other alternatives are available?
