Move Material-specific Banner tests to the appropriate test file:

  • Banner widget in MaterialApp test moved to material/banner_test.dart
  • CheckedModeBanner does not crash at zero area test moved to material/banner_test.dart

Remove Material import from widgets/banner_test.dart since all remaining tests only use widgets-level BannerPainter and BannerLocation APIs.

Update cross imports list to remove banner_test.dart from knownWidgetsCrossImports.

All tests pass and no formatting issues detected.

Code Review

This pull request correctly refactors Material-specific banner tests out of the general widgets test file and into the material test file. This improves the separation of concerns and removes an unnecessary dependency from widgets/banner_test.dart. The changes are clean and align with the goal of better test organization. I have one minor suggestion to improve code readability.

Merely "moving" the file does not address this issue.

The checked mode banner widget is also used for CupertinoApp, so the proper fix is to replace MaterialApp and friends in this file with their flutter/widgets counterpart. This is blocked on #180456

I did manage to fix this without moving the file in #181274

Maybe we should prefer that PR?

It was my bad; it seems like I misunderstood this task.

I agree that TestWidgetsApp is really needed. But I don't see it yet on the master.

I expected that TestWidgetsApp is required because, there will be a lot of defaults values to be passed.
But for this exact case I was able to use WidgetsApp with default parameters to simulate Material.
Now, I think we can create private _TestWidgetApp in each file where it's required by tests, and adjust it for that use case only without generating one universal TestWidgetsApp for all cases.

What do you think? Is it ok?

There is a TestWidgetsApp that will be introduced soon, but that PR is not yet merged. If it works for banner_test.dart by providing WidgetsApp with some defaults, then LGTM.

Whoops I should have left comment https://github.com/flutter/flutter/pull/181261/files#r2733374357 here. I think we should wait for TestWidgetsApp.
