This adds a smoke test for every single API example. It also fixes 17 tests that had bugs in them, or were otherwise broken, and even fixes one actual bug in the framework, and one limitation in the framework. The bug in the framework is that NetworkImage's _loadAsync method had await response.drain<List<int>>();, but if the response is null, it will throw a cryptic exception saying that Null can't be assigned to List<int>. The fix was just to use await response.drain<void>(); instead. The limitation is that RelativePositionedTransition takes an Animation<Rect> rect parameter, and if you want to use a RectTween with it, the value emitted there is Rect?, and one of the examples was just casting from Animation<Rect> to Animation<Rect?>, which is invalid, so I modified RelativePositionedTransition to take a Rect? and just use Rect.zero if the rect is null.
Example of switching between full-screen Flutter and Platform View
This project demonstrates how to bring up a full-screen iOS/Android view from a full-screen Flutter view along with passing data back and forth between the two.
On iOS, we use a CocoaPods dependency to add a Material Design button, and so
pod install needs to be invoked in the ios/ folder before flutter run:
pushd ios/ ; pod install ; popd
flutter run
