This disables the arrow key focus navigation for text fields. This was non-standard behavior for text fields, although it remains useful for other kinds of controls.

Fixes #42259

* add missing trailing commas

* add more missing trailing commas

* add more and more missing trailing commas

Add an autofocus parameter to widgets which use Focus widget internally, and update related docs.

This will allow developers to request that a particular widget be automatically focused when shown.

Enable selection by default for password text field and expose api to turn on and off context menu options (#34676)

This adds an example of how to move to the "next" field when using TextInputAction.next. This is all that is needed to have "next field" functionality in a field. I thought about making it the default when handling the "next" or "previous" actions, but it's better that the developer has control over whether or not they actually move to the next field, and within which scope.

CupertinoTextField now supports vertical alignment via the textAlignVertical parameter.

The text selection handles now feel a lot more responsive, and their implementation was cleaned up a bit.

scrollController param on TextField and CupertinoTextField

Adds a field that already exists in Material's TextField.

This reverts commit 18ca3754.

TextField and CupertinoTextField can now specify scrollPhysics. Cupertino defaults to bouncing now.

Adds the `minLines` and `expands` parameters for controlling text height.  The original PR was reverted, so this one contains a few extra fixes for the tests that were broken.

Fix the spelling errors in the dartdocs for the framework.

There are no functionality changes here, just documentation fixes.
