* globalToLocal was just broken when there was a rotation and a translation at the same time. This fixes that and adds a test. * update graphic used by spinning_mixed since the old one went 404. * simplify some of the code in the demo. * fix MatrixUtils.transformPoint to be consistent with how we transform points elsewhere. * stop transforming points elsewhere, just use MatrixUtils.transformPoint. * make the Widget binding handle not having a root element. * make the spinning_mixed demo update its widget tree.
Examples of Flutter's layered architecture
This directory contains a number of self-contained examples that illustrate Flutter's layered architecture.
-
raw/ These examples show how to program against the lowest layer of the system. They manually receive input packets and construct composited scenes.
-
rendering/ These examples use Flutter's render tree to structure your app using a retained tree of visual objects. These objects coordinate to determine their size and position on screen and to handle events.
-
widgets/ These examples use Flutter's widgets to build more elaborate apps using a reactive framework.
-
services/ These examples use services available in Flutter to interact with the host platform.
To run each example, use the -t argument to the flutter tool:
flutter run -t widgets/spinning_square.dart
