Skipping multiple_windows_test.dart because Windowing APIs are not enabled.

Windowing APIs are currently experimental. Do not use windowing APIs in
production applications or plugins published to pub.dev.

To try experimental windowing APIs:
1. Switch to Flutter's main release channel.
2. Turn on the windowing feature flag.

See: https://github.com/flutter/flutter/issues/30701.
