Draggable is now itself a gesture arena member. This means it won't
conflict with other gesture recognisers in the same path.
This also allows variants of Draggable that are triggered by other
gestures.
Also, some cleanup of DoubleTapGestureRecognizer, GestureDetector, and
PrimaryPointerGestureRecognizer.
Also, make MultiTapGestureRecognizer support a timeout for longpress.
Also, make Draggable data be typed.
Also, hide warnings about constructor warnings for now. Analyzer doesn't
support them yet. (Have to do this on a per-line basis)
Directions for future research:
- animating the avatar (enter/exit transitions)
- interaction with the navigator (canceling a drag on page navigation, etc)
- double-tap draggable
- runApp(new MaterialApp()) was crashing long after the constructor. Now
it asserts in a more useful location.
- remove the default name for NamedRouteSettings. It was unused anyway.
Now a RenderBox is considered hit if one of its children are hit or it itself
decides that it's hit. In particular, empty space inside a flex won't be hit
because none of the children are located there and a RenderFlex doesn't
consider itself hittable.

Paint is an argument on most methods of Canvas, and in many uses the Paint
contains only a color. In this case, return the Paint's value to native code
as an int instead of constructing a list of attributes.
This improved run time on a drawRect benchmark by 35%.
One Scaffold layout to rule them all
Expanded the existing CustomMultiChildLayout to handle all of the Scaffold's children.
This change also eliminates the FAB input dead-zone.
Make all the *GestureRecognizer classes inherit from a class called
GestureRecognizer. Give the old GestureRecognizer a name that is more
precise about its purpose. Remove the members of GestureArenaMember that
aren't used by GestureArenas.
- change how we expose settings at the RenderObject layer so that it's
easier to maintain.
- expose the Widget owner chain in the RenderObject layer debug output
- add debug info to RenderOpacity, RenderIgnorePointer, RenderListener
- make the output for text nodes prettier
