This adds a canRequestFocus and skipTraversal argument to FocusScope and FocusScopeNode, so that a scope can prevent being traversed.
This allows a fix for a problem in the gallery where the focus while traversing the list of items would sometimes appear to disappear, since it would be focusing things that were in the backdrop that were part of the tree, but were not visible.

* Responding to PR feedback.
* [Material] Create material Banner component (#36880)
This PR creates a new material widget for the Banner component. This includes a theme as well. This widget can be dropped into any application, ideally at the top of a listview or scrollview.
(cherry picked from commit 35b6d668e1)
Removed the use of ButtonTheme.bar in the Banner implementation.
* Updated documentation from PR review comments.
Update the flutter_gallery Slider demo by aligning the text field in the first slider, adding range slider examples (including custom range thumbs), and separating single slider and range slider examples with tabs.
This implements focus and hover handling for Material buttons. It inserts Focus widgets into the tree in order to allow buttons to be focusable via keyboard traversal (a.k.a. TAB traversal), and Listener widgets into the InkWell to allow the detection of hover states for widgets.

This PR introduces a number of changes and improvements to snack bars. This includes the ability to specify:
floating style of snack bars that adhere to the updated Material spec
elevation and shape on the SnackBar itself instead of relying on fixed values
a snackBarTheme as part of ThemeData which allows you to customize all of the above on an app-wide level.
This PR is includes the changes from #21484 as well as additional fixes and modifications. Thanks to @NikoYuwono for providing these changes and getting this off the ground!
Adds an adaptive constructor for the Material Slider. An adaptive widget is one that renders itself as Material on Android, and Cupertino on iOS. This work is based off of a similar feature on Switches: bbb080b#diff-fe2bb980c6207699cbf45538fe927afa.
The motivation for this change is that we should provide adaptive constructors for as many widgets as necessary in the Material library. In Material, it is suggested that the slider is an iOS-style slider.
Adds the "2D Transformations" demo to the gallery, which shows how to do things such as navigate around a map a la Google Maps, or show a full screen zoomable photo. The idea is to abstract this code into a first class widget soon.
