This makes the callback arguments to FocusableActionDetector optional, if you (for instance) only want to define shortcuts and actions and a focus node for something.
* Add clipBehavior to RenderFlex

* Fix rebase
* Add function to set structured error early
* Remove unused imports
* Save test handler in setUp
* Add utils file for shared test service
* Rename structured error functions

This adds a new navigationMode to the MediaQueryData that indicates how focusable controls should behave under different navigation modes, currently with two modes: NavigationMode.traditional, and NavigationMode.directional.
It may seem like focusing a disabled control is not desirable, but this is useful for user interfaces that use DPAD navigation because if a control gets disabled, losing focus is disruptive to the user, and it is difficult to control where the focus will end up unless it is done explicitly.
* Value Indicator uses Global position when calculating horizontal position
* fixed test
* fixed analyzer
* Made globalCenter variable and added comments
* Uses a special cursor value MouseCursor.defer to mark deferring. MouseTrackerAnnotation.cursor is now non-null. The mouseCursor argument of widgets or render objects can be null, which indicates using the default value.
* Moves SystemMouseCursors.uncontrolled to MouseCursor.uncontrolled.
* Changes how MouseCursor.debugDescription is defined. Previously MouseCursor.toString returns $runtimeType($debugDescription), while now it returns $debugDescription. Implementations of classes are updated, except for the ones of MouseCursor.defer and MouseCursor.uncontrolled are simply "defer" and "uncontrolled".
