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)
<!--
Thanks for filing a pull request!
Reviewers are typically assigned within a week of filing a request.

https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md
-->

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.

Add barrierColor property to showCupertinoDialog (#166911)
implimented https://github.com/flutter/flutter/issues/166910



https://github.com/user-attachments/assets/fe9aa2ce-b8a5-4458-b04a-781763959169

## How to Verify
- Set enableDrag: false in CupertinoSheetRoute or showCupertinoSheet.

```diff

showCupertinoDialog<void>(
      context: context,
+      barrierColor: CupertinoColors.activeOrange.withValues(alpha: 0.5),
      builder:
          (BuildContext context) => CupertinoAlertDialog(
            title: const Text('Alert'),
            content: const Text('Proceed with destructive action?'),
            actions: <CupertinoDialogAction>[
              CupertinoDialogAction(
                /// This parameter indicates this action is the default,
                /// and turns the action's text to bold text.
                isDefaultAction: true,
                onPressed: () {
                  Navigator.pop(context);
                },
                child: const Text('No'),
              ),
              CupertinoDialogAction(
                /// This parameter indicates the action would perform
                /// a destructive action such as deletion, and turns
                /// the action's text color to red.
                isDestructiveAction: true,
                onPressed: () {
                  Navigator.pop(context);
                },
                child: const Text('Yes'),
              ),
            ],
          ),
    );

```

- The following is a screenshot of
`examples/api/lib/cupertino/dialog/cupertino_alert_dialog.0.dart` after
adding `barrierColor: CupertinoColors.activeOrange.withValues(alpha:
0.5),`.

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.)

[Android] Implement setting sensitive content, take 2 (#167815)
> [!NOTE]  
> This PR lands https://github.com/flutter/flutter/pull/158473 (closed
due to confusing git-isms). Please see that PR for all comments and
discussion on landing this feature.

### Overview
Implements setting content sensitivity on Android via a new widget
called `SensitiveContent` that currently will only function on Android.

### How it's implemented
There are three different content sensitivity levels:
[`autoSensitive`](https://developer.android.com/reference/android/view/View#CONTENT_SENSITIVITY_AUTO),
[`sensitive`](https://developer.android.com/reference/android/view/View#CONTENT_SENSITIVITY_SENSITIVE),
[`notSensitive`](https://developer.android.com/reference/android/view/View#CONTENT_SENSITIVITY_NOT_SENSITIVE).
All except `autoSensitive` behave as their Android counterpart level
behaves (see links on the levels); for Flutter, `autoSensitive` will
behave the same as `notSensitive` though it is implemented as if it
works (see https://github.com/flutter/flutter/issues/160879 for more
details.

In any given Flutter view, each `SensitiveContent` widget sets a content
sensitivity level and there may be multiple `SensitiveContent` widgets
in the widget tree at a time, but only the most severe content
sensitivity level in the tree will be maintained in order to ensure
secure content remains obscured during screen projection. This means
that even widgets that are not visible may still impact the overall
content sensitivity of the entire Flutter view (see
https://github.com/flutter/flutter/issues/160051 for more details).

Under the hood, the implementation uses method channels. Theoretically,
this could cause a delay in setting the content sensitivity level and a
Flutter view being obscured during screen projection on time, so we will
investigate using JNIgen in the future (see
https://github.com/flutter/flutter/issues/160050 for more details). Over
the method channel, the framework will send a Flutter view ID and
content sensitivity level to the engine to set the expected content
sensitivity level for the view.

### Timeline

#### Required for feature shipping
- Land this PR with the method channel implementation of content
sensitivity.

#### Short-term follow up tasks
- Ensure every `FlutterView` has a unique ID for the native
`SensitiveContentPlugin` to identify them by:
https://github.com/flutter/flutter/pull/162685
- Add `SensitiveContent` widget to relevant Flutter widgets:
https://github.com/flutter/flutter/issues/167302

#### Long-term follow up tasks
- Convert this PR to use JNIgen:
https://github.com/flutter/flutter/issues/160050. Verify no frames are
dropped, revealing sensitive content during media projection:
https://github.com/flutter/flutter/issues/164820.

#### Stretch goals
- Make the `SensitiveContent` widget sensitive to the visibility of
child widgets: https://github.com/flutter/flutter/issues/160051
- Implement `autoSensitivity` mode:
https://github.com/flutter/flutter/issues/160879
- Investigate backwards compatibility for APIs < 35:
https://github.com/flutter/flutter/issues/159208

### Open questions
- ~Is it okay to hard-code the `FlutterActivity` and `FlutterFragment`
view IDs? Does this impact add-to-app in any way? I assume we would need
extenders of those classes to use a different view ID than the hardcoded
one.~ Approach not used.
- ~Should we expose `autoSensitive` for now? If so, what behavior should
it have?~ Exposing `autoSensitive` as if it works.

### One way to test this PR (rough steps)
1. Create a Flutter app that has some number of `SensitiveContent`
widgets.
9. Run the app on an emulator/device that runs API 35 and has the Google
meets app downloaded.
10. Start a Google meets meeting and screen share (works with full
screen and single app mode).
11. Join the Google meets meeting from another device and witness a
blacked out screen if content has been marked sensitive.

Fix date picker flickering (#167976)
## Description

This PR fixes a `DatePicker` flickering issue observed on some devices
with a small display.

### Before

When the date picker input dialog is shown the virtual keyboard opens
and reduces the available height. The current logic reacts by removing
the picker `TextField`. Because there is no more `TextField` the virtual
keyboard is hidden and the available height increases, at that moment
the `TextField` is shown again. Due to autofocus the virtual keyboard
opens which leads to the removal of the `TextField` and so on.


https://github.com/user-attachments/assets/deb70f2e-1c8b-47a9-9db6-47bc521e4eb7


### After

When there is not enough vertical space for the input date picker
dialog, the header is hidden instead of hiding the `TextField`.

Fix CarouselView.weighted crashes when initlal viewportDimension is 0.0 (#167628)
## Description

This PR fixes `CarouselView.weigthed` crashes due to given constraints
being zero (which happen, for instance, when viewportDimension is 0.0).
 
At startup, a warm-up frame can be produced before the Flutter engine
has reported the
initial view metrics. As a result, the first frame can be produced with
a size of zero. In the context of CarouselView this leads to some
problems mainly related to division by zero.

Similar to https://github.com/flutter/flutter/pull/167271 which
addressed the same problem for `CarouselView`.

## Related Issue

Fixes https://github.com/flutter/flutter/issues/167621

## Tests

Adds 3 tests.

Fix hit-testing order in semantics (#167522)
Fixes https://github.com/flutter/flutter/issues/163576

In `updateWith()` method, `_replaceChildren()` is called to generate
`_children` list. `_children` list is used to generate the hit test
order (`childrenInHitTestOrder`).

In `_replaceChildren()`, `childrenIn**Inverse**PaintOrder` is directly
assigned to _children, so _children itself follows hit test order. So
when we generate the `childrenInHitTestOrder`, we don't need to reverse
the children again.

Control paint order / z-order of slivers (#164818)
Fixes #145592.

When slivers in a CustomScrollView overlap, this makes it possible to
control which of the slivers will sit in front of the other one, meaning
that it paints last and gets hit-tested first.

In this version there are two choices: the first sliver paints in front,
or the last sliver paints in front. The first sliver in front is the
default; it's the behavior needed for SliverAppBar, or other situations
where the first sliver is some sort of header.

The existing behavior is actually quite a bit more complicated than
that, with the "center" sliver painting in front, plus it varies
depending on `shrinkWrap`. As far as I can tell this behavior isn't
documented anywhere. It's equivalent to first-sliver-in-front whenever
`CustomScrollView.center` isn't being used; and in fact there don't seem
to be any tests in the tree that notice the difference between the
existing behavior and first-sliver-in-front.

So although I actually have an implementation that preserves the more
complex existing defaults, I'm hopeful we won't need it: if neither
google3 nor customer tests are relying on that undocumented distinction
either, then we can go ahead and simplify this behavior without a
breaking change.

Update platform views documentation with 4 standard names and abbreviations (#167752)
After talking with @gmackall we are going to try to standardize on 

Virtual Display (VD) 
Hybrid Composition (HC) 
Texture Layer Hybrid Composition (TLHC)
Hybrid Composition++ (HCPP) 

for our documentation covering android platform views and how we
describe the code to each other.

For example HC++ would be discouraged, so would referring to HC as
expensive.

This pr also removes TargetSdk since that annotation has been deprecated
for a number of years and can be wholly replaced by the already used
RequiresApi annotations.

Wire up MenuAnchor, MenuBar, MenuItem-related widgets to aria roles (#165596)
This PR is to wire up `MenuAnchor` related widgets to SemanticsRole.
* When use `MenuAnchor` and a menu is opened, the menu has
`SemanticsRole.menu`.
* `MenuBar` has `SemanticsRole.menuBar`
* `MenuItemButton` has `SemanticsRole.menuItem`
* `SubmenuButton` has `SemanticsRole.menuItem` with `aria-haspopup`
attribute setup.
* `CheckboxMenuButton` has `SemanticsRole.menuItemCheckbox`
* `RadioMenuButton` has `SemanticsRole.menuItemRadio`

This PR also includes some changes related to `OverlayPortal` and
`RawMenuAnchor` so the "button" and the "menu" that the button opens has
a "parent-children" relationship. Previously, they are siblings
relationship which will cause some navigation issue in a11y.

EditableText should not allow horizontal scrolling on iOS (#162841)
Fixes #25553 

On iOS single-line TextFields are not scrollable with user input, for
example a pan gesture to move the viewport. They can still be scrolled
when the user drags the selection handles. Scrolling remains the same
for multi-line TextFields. A user can override this by providing
CupertinoTextField/TextField/EditableText with a custom `scrollPhysics`.

Remove use of announce in time_picker and remove double Feedback.forTap calls (#167241)

This pull request replaces the use of the deprecated announce calls with
idiomatic Semantic widgets and also removes the extra `Feedback.forTap`
call. The `InkWell` widget already wraps the onTap with the
`Feedback.forTap`. I also made sure sure that existing functionality is
not impacted.

Add more visual feedback to Slider with slideOnly interaction (#165306)
<!--

Sliders with `allowedInteraction: SliderInteraction.slideOnly` gave no
interaction feedback, if they are grabbed and moved along the track
instead of the handle, despite having the exact same behaviour
otherwise.

With this change, the handle becomes "active" (elevate+overlay) as soon,
as the track is tapped.

Fixes #165304

Make InputDecorator start padding compliant with M3 spec (#162157)
## Description

This PR makes InputDecorator padding for the input content, the helper
and the counter compliant with the M3 spec.
The padding should be 16 pixels instead of 12 pixels (which is the
current value).

See
https://m3.material.io/components/text-fields/specs#0d36c3fe-7948-4ec2-ab8a-4fe39cca19cc
for filled text fields and
https://m3.material.io/components/text-fields/specs#605e24f1-1c1f-4c00-b385-4bf50733a5ef
for outlined text fields.

### Before:

The paddings for the input content, the helper and the counter are not
compliant with the M3 spec (12 pixels instead of 16 pixels):

### After:

The paddings for the input content, the helper and the counter are
compliant with the M3 spec (16 pixels):

Fix keyboard cover SearchAnchor list results (#165382)
Fix https://github.com/flutter/flutter/issues/159261

We can leverage `MediaQuery.viewInsets` to handle this case. Once the
keyboard prompts and covers the SearchAnchor suggestion list, it will
need a bottom padding equivalent to
`MediaQuery.viewInsetsOf(context).bottom` so that it's possible to view
the whole list.

Add a DrivenScrollActivity.simulation constructor (#166730)
I'd like to have a scroll activity that drives the scroll view through a
particular animation -- just like a DrivenScrollActivity does -- but
where the animation doesn't have an end point or duration that's known
when the animation begins.

(Concretely, this is to implement a "scroll to the end of history"
button in the Zulip message list. The end point is maxScrollExtent...
except that maxScrollExtent while in the middle of history is only an
estimate, and will change as the list view scrolls through shorter and
longer messages.)

That means the animation is naturally described by a Simulation, but not
by the parameters accepted by the current DrivenScrollActivity
constructor, or by the animateTo method which wraps it.

I think this can be handled quite cleanly with an alternate constructor
on DrivenScrollActivity, one that accepts a Simulation instead of the
from/to/duration/curve parameters accepted by the default constructor.
The new constructor is very similar to the constructor of
BallisticScrollActivity.

Most of the changes here are in revising the docs of both
DrivenScrollActivity and BallisticScrollActivity. The docs had
characterized the difference between the two as about using a Simulation
vs. the from/to/duration/curve animation parameters, but I think that's
never been the most important difference between them: the key
difference is really the `goBallistic` calls in BallisticScrollActivity,
particularly in `applyNewDimensions`, and the implications those have
for how the simulation needs to relate to the scroll physics. So this
rewrites the docs to describe that.

Fix CarouselView crashes when initlal viewportDimension is 0.0 (#167271)
## Description

This PR fixes CarouselView crashes due to viewportDimension being 0.0.
 
At startup, a warm-up frame can be produced before the Flutter engine
has reported the
initial view metrics. As a result, the first frame can be produced with
a size of zero. In the context of CarouselView this leads to some
problems mainly related to division by zero.
