* Added customizable drawer edge drag width parameter to Drawer and Scaffold

* Fix Drawer drag area width for notched devices

* Update Drawer tests to reflect necessary LTR and RTL Drawer edge widths

* Add DefaultTextStyle parent widget to Tooltip Overlay

* Add test against fallback DefaultTextStyle

This improves the ability to debug focus manager issues. It's not meant to be used by developers unless they're debugging problems with the focus manager itself.

Fix a bug in CupertinoTextField where resizeToAvoidBottomInset didn't work.

This reverts commit 92ef2b9c.

This requires either runApp() or
WidgetsFlutterBinding.ensureInitialized() to have been called before
using any MethodChannels. Plugins broadly rely on MethodChannels and
right now there's no general requirements that they be constructed
within the runApp call, so the ecosystem breakages from this are broader
than originally thought. Reverting for now.

Vibrate when starting scrollbar dragging.

* Add checkColor to CheckboxListTile

* Create second paint for drawing check and dash

* Add activeColor test for Checkbox
