- I extracted the BuildScheduler into a separate binding.dart file.
- Various changes to expose private members that are needed by
binding.dart.
- Registering the render objects for event dispatch.
- Convert the tests to use the new binding mechanism.
This doesn't yet have a RenderView or event handling.
This patch contains a prototype of a new widget framework. In this framework,
Components can be reused in the tree as many times as the author desires. Also,
StatefulComponent is split into two pieces, a ComponentConfiguration and a
ComponentState. The ComponentConfiguration is created by the author and can be
reused as many times as desired. When mounted into the tree, the
ComponentConfiguration creates a ComponentState to hold the state for the
component. The state remains in the tree and cannot be reused.
