Add landmark roles (#168931)
This PR is to add ARIA landmark roles to `SemanticsRole`: complementary,
contentInfo, main, navigation and region.

I skipped `sectionhead` because it is an abstract role based on the [MDN
docs](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Reference/Roles/sectionhead_role#:~:text=The%20structural%20sectionhead%20role%20is%20an%20abstract%20role%20for%20the%20subclass%20roles%20that%20identify%20the%20labels%20or%20summaries%20of%20the%20sections%20they%20label.%20The%20role%20must%20not%20be%20used.)

Adds radio group widget r2 (#168161)
<!--

previous https://github.com/flutter/flutter/pull/167363

I have to factor out abstract class for RadioGroupRegistry and
RadioClient which are subclassed by RadioGroupState and RawRadio
respectively.

I have to do this because the RadioListTile that has 2 focusnode one for
listTile and one for the radio it builds. The issue is that RadioGroup's
keyboard shortcut has to tightly couples with the focus node of each
radio, but the radioListtile has to mute the radio's focusnode so it can
act as one control under keyboard shortcut

d582b35809/packages/flutter/lib/src/material/radio_list_tile.dart (L484)

Therefore i abstract the out the logic of RadioGroup so that another
widget can participate by implementing the interface.

Check to see if previous page is laid out before starting hero flight (#169633)
Fixes #168267

When going back to a page that never rendered with a hero transition,
the app was hanging. This adds a check to see if a page needs to layout
before starting the hero flight, and if so, adding a frame delay.

Don't show SystemContextMenu for SelectableText (#169238)
Goes back to using the Flutter-drawn context menu for SelectableText.
Currently, SystemContextMenu requires an active text input connection to
work. This snuck in because SelectableText is based on EditableText.

[web] Fix unresponsive input above SelectionArea in Safari and Firefox. (#167275)
Fixes https://github.com/flutter/flutter/issues/157579

### Description

When the `TextField` is placed above the `HtmlElementView`, it becomes
unresponsive on Safari and Firefox. After the investigation, I found
that this happens because the underlying `input`/`textarea` loses focus,
leading to not listening to the keyboard input.

After some investigation, I found out that calling `preventDefault` on
`mousedown` events on SelectionArea's `div` element prevents the
`input/textarea` from losing focus.

This PR focuses on `SelectionArea`, but there is the same issue
happening in the `pointer_interceptor ` package
https://github.com/flutter/flutter/issues/157920. If this solution is
accepted, then I could file a separate PR for `pointer_interceptor`
package with the same fix.

<summary>Old description</summary>

The fix I am proposing is to delay the `moveFocusToActiveDomElement` by
using `Timer`. I am not sure whether this is a proper fix, as it looks
like the issues may be in the way pointer events are handled. I tried
adding `event.preventDefault()` after `_callback(event, pointerData)` in
`pointer_binding.dart` and the issue was fixed, but then text selection
in `SelectionRegion` became broken.

#### Firefox

On `TextField` tap, the focus moves to the `input`, and then back to the
`flutter-view`. You can take a look at the "Before" recording.

#### Safari

Like in Firefox, on `TextField` tap, the focus moves to the `input`, and
then back to the `flutter-view`. You can take a look at the "Before"
recording.

| Before | After |
| :---: | :---: |
| `flutter-view -> input -> flutter-view` | `flutter-view -> input ->

/> |

#### Chrome

The issue is not happening on Chrome. If you take a look at the
recording, you will notice that on a `TextField` tap, the focus moves
the following way: `flutter-view -> input -> input`. The reason why it
doesn't move to `flutter-view` is that we have a
`moveFocusToActiveDomElement` call in the `handleBlur` function. As far
as I understand, it prevents `input` from losing focus.
However, the same call in Firefox doesn't prevent input focus loss.
In Safari, it fixes the issue, but listening to `blur` events is not a
way to go, according to the following comment
https://github.com/flutter/flutter/blob/master/engine/src/flutter/lib/web_ui/lib/src/engine/text_editing/text_editing.dart#L1385-L1391

[Cupertino] Apply RSuperellipse to most Cupertino widgets (#167784)
This PR applies RSuperellipse to most Cupertino widgets. I got the list
by searching for `ClipRRect`, `drawRRect`, and `BoxDecoration` (with
`borderRadius`) through the package. They're replaced by
`ClipRSuperellipse`, `drawRSuperellipse`, and `ShapeDecoration`
respectively.

There are a few widgets that I didn't apply:
* `CupertinoTextField` as well as its related widget
`CupertinoSearchTextField`, because `CupertinoTextField` expects a
`BoxDecoration` argument. Migrating it is nontrivial and will take place
in a separate PR.
* `CupertinoTextSelectionToolbar`, because it seems complicated
(containing a lot of paths). I wonder if it's possible to replace the
clipPath with clipRRect/clipRSe for better performance.
* `CupertinoSwitch`. I suspect it's not an squircle since it tightly
contains a full circle.

Fixes https://github.com/flutter/flutter/issues/13914.

Add support for hiding widget subtrees from the widget inspector (#169007)
This PR introduces two new widgets:

- `DisableWidgetInspectorScope`, which hides its children from the
widget inspector
- `EnableWidgetInspectorScope`, which makes its children available to
the widget inspector

These widgets are used to inform the `WidgetInspectorService`'s
`InspectorSerializationDelegate` when it should be omitting
`DiagnosticableNodes` from the response when building the root widget
tree for the inspector.

This functionality is meant to be used by developer tooling and packages
that want to prevent unnecessary implementation details from polluting
the inspector and possibly confusing end users.

This change also includes some minor updates to the Widget Preview
scaffolding template to hide the scaffold's implementation details and
only show details for the previews defined by the user.

Part of https://github.com/flutter/flutter/issues/166423

This change reverts the following previous change:
Resolves partly https://github.com/flutter/flutter/issues/165510


**Context:** This issue originates from
https://github.com/flutter/flutter/issues/99715, where it was reported
that `liveRegion` alone was insufficient for announcing form validation
errors. While `liveRegion` announces the first error encountered,
subsequent submissions with the same error message on Android would not
trigger a re-announcement.

**Original Solution:** Pull request
https://github.com/flutter/flutter/pull/123373 addressed this by
implementing the `announce` event to ensure error messages were
consistently announced, even for repeated submissions.

**Native Android Behavior (Jetpack Compose):** In native Android
development using Jetpack Compose, setting the `isError` property of a
`TextField` to `true` triggers Talkback to announce "Error invalid
input." This announcement occurs *only* on the initial change to the
error state. Subsequent errors, even if the `isError` property remains
`true`, are not re-announced. This behavior closely mirrors the
functionality of `liveRegion`, with the key difference being that
`liveRegion` also announces the specific error text, in addition to the
general error state. Testing in a native Jetpack Compose application
confirms this behavior and provides a valuable comparison point against
the current Flutter form example.

**Suggested Action:** **Fork** the behavior in
https://github.com/flutter/flutter/pull/123373. Reinstate the use of
`liveRegion` for error announcements within `widgets/Form` for Android
and keep other platforms the same.

Wire up the system text scaler from PlatformDispatcher (#159999)
The equality of 2 `SystemTextScaler` is determined by the platform's
`textScaleFactor` scalar, because the `scale` method is always
monotonically increasing wrt `textScaleFactor`.
On Android the scalar reflects the user configuration in system
preference it seems:

Android home/end keyboard shortcut support (#168184)
This PR adds support for Home and End keyboard shortcuts on Android. It
seems like we had mistakenly purposely disabled them on Android before
(or maybe native Android recently added support for them?).

In the process I also noticed that Linux was missing home/end+control
shortcuts, so I added them. I confirmed that these are supported
natively using my Linux machine.

Add Option to disable full selection on focus on TextField, TextFormField, and EditableText (#163491)

This is adding a field to EditableText, TextField, and TextFormField to
disable highlighting the entire field on web and desktop when it
receives focus. The field is called highlightAllOnFocus. It does nothing
on other platforms because the other platforms don't highlight the
entire field on focus.

Note: I am not attached to this variable name, but it was the best I
could think of... But I am very open to better suggestions 😆

Thank you for everything!

Make MergeSemantics be able to merge customAction (#168414)
Fixes https://github.com/flutter/flutter/issues/166588

When merging semantics, an empty customSemanticsActions was always used
instead of using the `_customSemanticsActions` of the current semantics
node.

[Widget Inspector] Add on-device button for changing default "tap" behavior (#167677)
Fixes https://github.com/flutter/flutter/issues/166118

Adds a second button to the on-device inspector that allows a developer
to temporarily disable the default "tap triggers widget selection"
behavior without fully exiting out of widget selection mode. Fixes an
issue where enabling/disabling widget selection is destructive for some
app set-ups, causing the developer's app to lose state.

When the `floatingActionButton` is clicked, it should print the position
of the green `Container`. The expected result is `Offset(40.0, 40.0)`,
but the actual result is `Offset(0.0, 40.0)`. `hitTest` also produces
incorrect results. This PR fixes the issue.

[ Widget Preview ] Improve widget inspector support for widget previews (#168013)
In order to prevent the widget inspector from being able to select and
inspect elements of the widget previewer's scaffolding, this commit
consists of two notable changes:

1) A `debugWillManuallyInjectWidgetInspector` property has been added to
`WidgetsBinding`. Setting this property to true before running the
application will prevent `WidgetsApp` from injecting a `WidgetInspector`
instance into the widget tree, even if the widget inspector is enabled.
This means that the widget inspector will not be able to select and
highlight widgets by default, requiring `WidgetInspector` to be manually
wrapped around widget trees that should be inspectable.

2) The widget_preview_scaffold template has been updated to set
`debugWillManuallyInjectWidgetInspector` to true by default, and to wrap
individual previews provided by the developer with an instance of
`WidgetInspector` to restrict widget inspection to the contents of the
preview.

This change also includes a minor bug fix for situations where
`WidgetInspector` is inserted into an unconstrained context. Previously,
the `WidgetInspector`'s `_InspectorOverlay` would attempt to take up as
much space as possible, causing an overflow. To fix this, the
`_InspectorOverlay` is wrapped with `Positioned.fill(...)` to force it
to take on the same size as its parent `Stack`.

Fix: Ensure Image.errorBuilder reliably prevents error reporting (with addEphemeralErrorListener) (#167783)
_An alternative to https://github.com/flutter/flutter/pull/166130 using
`addEphemeralErrorListener`.
The following text is adapted from
https://github.com/flutter/flutter/pull/166130._

**Problem:**

Currently, when using an `Image` widget with an `errorBuilder`, if the
widget is removed from the widget tree (e.g., due to navigation or
`setState`) *after* the image loading process has started but *before*
an asynchronous loading error is reported back, the error can still be
reported via `FlutterError.reportError`. This occurs because the
`_ImageState` listener is removed upon disposal, and the
`ImageStreamCompleter` subsequently treats the error as unhandled,
logging it despite the developer's intent to handle it via the
`errorBuilder`. This leads to unexpected noise in logs and crash
reporting systems.

**Solution:**

This PR utilizes `addEphemeralErrorListener`, which allows the image
stream to be disposed while having an error reporter. The error will not
be reported as long as there is an error reporter. The `Image` widget
adds an empty error reporter if `errorBuilder` is not null.

**Related Issues:**

* Fixes #97077
* Related: #107416, #69125, #34451,
Baseflow/flutter_cached_network_image#780

**Tests:**

* Added a new test case `errorBuilder prevents FlutterError report even
if widget is disposed` to `test/widgets/image_test.dart` to specifically
verify the fix for the disposal race condition.
* This test was written by @/perlycke in
https://github.com/flutter/flutter/pull/166130.
* Existing tests in `test/widgets/image_test.dart` (including golden
tests like 'Failed image loads in debug mode') pass with these changes
without requiring updates.

**Breaking Changes:**

* None. This change fixes incorrect behavior and preserves expected
debug visuals. The internal mechanism for reporting errors when no
`errorBuilder` is present has shifted, but the user-facing outcome is
consistent.

fix(a11y): check for remaining relevant text direction properties (#165028)
<!--

We faced an issue that the assert at
https://github.com/flutter/flutter/blob/3.29.1/packages/flutter/lib/src/semantics/semantics.dart#L497-L500
was triggering although our widget was placed under a `MaterialApp` and
therefore had a text direction set.

Turns out that `_getTextDirection()` just was not checking for
`attributedValue`, etc.

Refactor more logic from radio and cupertino radio (#167764)
<!--

-->

This is in prepare for https://github.com/flutter/flutter/pull/167363

The goal for this refactoring is to make sure the new RadioGroup widget
can be used for both CupertinoRadio and Radio, and thus the widget has
to be in widget layer to avoid duplicating code.

Currently CupertinoRadio and Radio shares ToggleableStateMixin in widget
layer. but the mixin itself doesn't contains enough data to implement
radioGroup. Therefore, I moved more share logic from CupertinoRadio and
Radio to widget layer and created a RadioBase widget.

Let DrivenScrollActivity subclasses customize handling of overscroll (#166731)
This functionality is useful in a custom DrivenScrollActivity subclass,
just like it's useful in a BallisticScrollActivity subclass.

For example, if one calls `animateTo(0, …)` to scroll to the beginning
of a list, there will be no overscroll (provided the chosen curve
doesn't go beyond its endpoint). The same is true if one calls
`animateTo(position.maxScrollExtent, …)` to scroll to the end... as long
as the value of maxScrollExtent at the beginning remains accurate when
the scroll view reaches the end. If one wants to scroll to the end and
avoid overscroll even when that turns out to be closer than the initial
estimate found in maxScrollExtent, then that calls for customizing the
overscroll behavior of a DrivenScrollActivity.

Fortunately we don't need to invent any new API in order to do this:
BallisticScrollActivity already has an API for the exact same need. So
copy that API -- name, docs, and all -- to keep these two classes
aligned.

(It might also be useful to take much of what these have in common and
factor that out to a common subclass; but that'd be for another PR.)
