Code Review
This pull request modifies PlatformViewIOS to allow setting the application locale even before a FlutterViewController is attached. It achieves this by caching the locale in a new application_locale_ member variable and applying it when the view controller is set. The change also includes a new unit test to verify this behavior. My review provides suggestions to improve code maintainability by refactoring duplicated logic and to fix a potential syntax error in the new test.
