Ian Hickson e01592a0c0 Fix globalToLocal and update spinning_mixed (#6035)
* 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
