This flag controls Android's keyboard suggestions on/off

Use assertions to prevent multiline password fields from being created

In #42533, I disabled the up/down arrows for focus navigation in text fields, but we thought of a better way to do it, so this is that better way.

This change reverts the other change, and instead it tests the context of the node in the action to see if it's an EditableText node. If so, then it doesn't do the navigation action.

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

* Adds a new parameter bool opaque to MouseRegion
* The same to RenderMouseRegion and AnnotatedRegionLayer
* Add findAnnotations to Layer 

* add missing trailing commas

* add more missing trailing commas

* add more and more missing trailing commas

* remove splash logic

* update tests

Added docs examples of getting the string from a TextField

This reverts commit 6ad88bd5.

This changes the behavior of text fields, Material buttons, and Chips so that if they are disabled they lose focus. Before this change, it was possible to disable a control and then use focus traversal to reach it anyhow, and in the case of text fields, enter text into a disabled field.

Fixes #33985

* Add images and update examples for top widgets:

  - scaffold
  - text field
  - image
  - text
  - row
  - column
  - stack

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.

Show and hide the text selection menu at the correct time with various gestures in the text field.

Adds the `textAlignVertical` param to TextField and InputDecorator, allowing arbitrary vertical positioning of text in its input.

Fix exception that was happening when double-double-tapping a TextField (or double long tapping).

scrollController param on TextField and CupertinoTextField

This adds support for an animated focusColor and hoverColor to InputDecorator. This color will blend with the background over a fade in period whenever the InputDecorator is focused or hovered, respectively.

It also adds a Listener to the TextField to listen for hover events.
