We were using the `defaults` command-line utility to parse
Plist files, but it was never supported by Apple, and it
appears that in an upcoming OS release, it will be less likely
to work:

> WARNING: The defaults command will be changed in an upcoming
> major release to only operate on preferences domains. General
> plist manipulation utilities will be folded into a different
> command-line program.

* Add an 'unfocusable' focus node to allow developers to indicate when they don't want a Focus widget to be active

* more unfocusable changes. not working.

* Switch to focusable attribute

* Rename to canRequestFocus

* Turn off debug output

* Update docs

* Removed unused import

Teach Layer and its implementations, RenderObject and its implementations, and PaintingContext to reuse engine layers. The idea is that a concrete RenderObject creates a Layer and holds on to it as long as it needs it (i.e. when it is composited, and the layer type does not change). In return, each Layer object holds on to an EngineLayer and reports it to the engine via addRetained and oldLayer. This allows the Web engine to reuse DOM elements across frames. Without it, each frame drops all previously rendered HTML and regenerates it from scratch.

Changes a hard-coded value to a controllable parameter.

* Broadcasting popRoute and pushRoute methods via SystemChannels.navigation. These messages will be used in flutter_web to detect the route

* Broadcasting popRoute and pushRoute methods via SystemChannels.navigation. These messages will be used in flutter_web to detect the route

* Reverting all unrelated formatting changes.

* Adding unit tests. Adding more comments.

* Changing string method names with constant strings.

* Fixing a constant strings.

* Fixing analyzer error.

* Fixing more white space.

* Changing the method names. Adding comments to the SystemChannels

* Comment and code name fixes

* replacing the comment with reviewer suggestion.

* addinf systemchannels.navigation mock to test bindings

* Adding a new class for sending route change notrifications. The nottifications are only sent on web. This should fix breaking android/ios

* using new class RouteNotificationMessages in navigator

* Fixing analyzer issues.

* fixing cycle dependency

* fixing github analyze error

* dartfmt two new classes. trying to fix anayze errors

* Update route_notification_messages.dart

* trying to fix white space errors

* Add toggle buttons assets

* Reorder video location, reduce height of videos

* Reduce height of toggle buttons assets

This adds a FocusHighlightMode to the FocusManager that switches based on the type of input that has recently been received. The initial value is based on the platform, but is updated as soon as user input is received. There is also a FocusHighlightStrategy enum so that the developer can change the strategy to a fixed value if needed.

The default is to automatically detect the mode based on the last type of user input. If they use a mouse or keyboard, it shows the focus highlights. If they use a touch interface, then the highlights disappear. This is consistent with the way that Android and Chrome work. The controls still receive focus, only the display of the highlight changes.

Text fields show the focus highlight regardless of the focus highlight mode.

* Take growth direction into account when computing value for getOffsetForReveal in AxisDirection.right and .up conditions.

* Add alignment 1.0 test to left - reverse growth

* Add Reverse List showOnScreen test

* Formatting fix.
