Resizing a macos window after runApp was called twice caused the engine to hang. In order to test the fix, four approaches were possible.

  1. Write a fixture test in the engine.

not possible as the test would require the flutter framework and there cannot be a circular dependency

  1. Write a native unit XCTest

I couldn't get the FlutterViewController to display the FlutterDartProject that would reproduce this bug

  1. Write a native XCUITest

The UI test required an Apple Script to resize the window with sudo permissions... not a favorable approach

  1. Write a flutter integration test

Approach 4 seems reasonable as it was the easiest to implement.

This commit contains the application and the integration tests that make sure the app works. I plan to follow up on this PR with another that implements the test that checks whether an app hangs after resizing.

partial fix to #92673

Can you use an existing integration test for window resize instead of making a new one?

@jmagman I can.

channels is likely the best candidate, but the app tests the method channel itself, not platform functionality.
platform_view is also close, but it's an example and it would be weird if we had a resize implementation just floating around for macos.

I think the reason I did it this way is to separate concerns of the integration tests. Regardless, if you want, I can add the test to either of those.

That doesn't scale well, we don't need a new integration test project for every test. How about ui?

Exactly, resize a window for an existing integration test instead of making a new one. Windows and Linux should likely have similar tests.

(not that you should implement them, just a comment)
