Make a11y computeChildGeometry slightly faster (#177477)
This is not a fix for #166173, it's only a by-product. The fix will be
in separate PR, this includes the unrelated code changes to make that PR
smaller.

According to `bench_material3_semantics`, this reduces
`Semantics.ensureGeometry` by ~100 μs (321.6 μs -> 228.9 μs).

Fix Image.network not using cache when headers are specified (#176831)
Fix a bug introduced by 97aae2ad3 (#171916), where `hashCode` is giving
different results for values which `==` says are equal. Which broke
caching for uses of `Image.network` widget when `headers` map was
passed.

Add non uniform TableBorder (#175773)
Re-implementation of PR #172441

## Add non-uniform border radius support to TableBorder
This PR extends TableBorder to support border radius even when the outer
border sides have different widths but the same color, similar to the
non-uniform border support added to Border in #121921.

### Changes
- Enhanced border rendering logic: TableBorder can now apply border
radius when outer border sides have uniform colors but non-uniform
widths/styles
- New helper methods: Added `outerBorderIsUniform` property and
`distinctVisibleOuterColors()` method to determine border uniformity
- Optimized paint method: Refactored the paint logic to handle three
scenarios:
  1. Fully uniform borders (existing optimized path)
2. Outer borders with uniform colors but non-uniform widths (new
non-uniform border radius support)
3. Completely non-uniform borders (fallback to standard border painting)

### Before/After
- Before: TableBorder with border radius required all sides (including
inner borders) to be completely identical.
- After: TableBorder with border radius only requires outer border
colors to be the same, allowing different widths per side.

### Example Usage
```dart
TableBorder(
  top: BorderSide(color: Colors.blue, width: 3.0),
  right: BorderSide(color: Colors.blue, width: 1.0),  // Different width
  bottom: BorderSide(color: Colors.blue, width: 2.0), // Different width  
  left: BorderSide.none,                              // No border
  horizontalInside: BorderSide(color: Colors.red, width: 1.0), // Different color OK
  verticalInside: BorderSide(color: Colors.red, width: 1.0),   // Different color OK
  borderRadius: BorderRadius.circular(8), //  Now works!
)
```
Fixes: #173193

Add radius clamping to web RSuperellipse (#172254)
This PR fixes rendering errors on Web when the provided corner radii sum
up larger than the size. It implements radius scaling using the same
algorithm as in [the C++
implementation](b2d4210b37/engine/src/flutter/impeller/geometry/rounding_radii.cc).

Before: (error emerges for r>100, since the height is 200)
<img width="664" height="509" alt="image"
src="https://github.com/user-attachments/assets/eb526338-84d9-4eca-975b-d44bee0c11ac"
/>

After: (it stays this way for r>100)
<img width="611" height="471" alt="image"
src="https://github.com/user-attachments/assets/08ca2499-d5f7-47e1-9ecf-29f60c968016"
/>

It also fixes a bug that uses an incorrect starting point. 

Both changes are backed by the new test cases in
`rounded_superellipse_border_test.dart`.

fix: 🐛 Add equality and hashCode implementations to ResizeImage (#172643)
This PR adds implementations for `==` and `hashCode` in the
`ResizeImage` class.

#### Reason

Previously, `ResizeImage` instances with identical configuration (e.g.,
same width, height, image provider, and allowUpscaling flag) were not
treated as equal. As a result, comparing two such instances would always
return false, even when they have the same values.

#### Fixes

Closes #172642

add debugPaintTextLayoutBoxes for debugging text layout (#168876)
Text vertical alignment is a common complaint and one of the most common
causes is different type faces being used in the same paragraph (for
instance, when there's English / Arabic in the same paragraph so the
default font doesn't contain the required glyphs for some characters).

Hopefully this flag is going to make debugging alignment issues a bit
easier, and in some github issues attaching screenshots with the flag on
will be helpful for diagnosing the issue.

### What the layout boxes look like 
```dart
final testText =
    'Quick brown fox, نص, trailing spaces${" " * 100}'
    'new line at the end.\n\n\n\n';

Column([
              Text(testText, style: TextStyle(height: kTextHeightNone)),
              Text(testText, style: TextStyle(height: 1.0)),
              Text(
                testText,
                style: TextStyle(height: kTextHeightNone),
                strutStyle: StrutStyle(fontSize: 30),
              ),
])
```

Fixes https://github.com/flutter/flutter/issues/164405

The previous behavior of `RenderWebImage` for layout and positioning did
not work for all values of `BoxFit` and `AlignmentGeometry`. This PR

[web] Remove all usages of js_util. (#171871)
Closes https://github.com/flutter/flutter/issues/143396

### Description
- Removes `js_util` library usage across the codebase

In order to get rid of `dart.library.js_util` in
[`kIsWeb`](e8d56b25c0/packages/flutter/lib/src/foundation/constants.dart (L83))
constant the dart analyzer has to be updated first. For now, the
`dart.library.js_util` value is hardcoded in the source code:
1a88edceb7/pkg/analyzer/lib/src/dart/constant/evaluation.dart (L2908-L2915).
So we either have to update this value or wait for the
https://github.com/dart-lang/sdk/issues/50045 fix.

[Impeller] Fix the algorithm for building paths for RSuperellipses with sharp corners (#171351)
Fixes https://github.com/flutter/flutter/issues/170593.

The problem was caused by errors in the path building algorithm that
handles sharp corners and unequal width/height.

(Honestly the errors for the `scale_sign` part and the transform matrix
part were kind of embarrassing. I don't know what I was thinking when I
wrote them.)

Avoid using a Key whose only purpose is to be looked up in a test (#170952)
This PR investigates moving away from the few places where we rely on
Keys to instead solely look up a widget in a test. Reasons:

 * No extra stuff in users' apps that they don't need for production.
* Avoid collisions between Keys in users' apps that might have the same
identifier string.

I'm definitely still up for discussion on whether or not this is a good
idea!

Fix gestures not being recognized in <img>-backed NetworkImages (#171190)
On the web, when a `NetworkImage` falls back to an `<img>`
element-backed implementation, the gesture events were being lost
because the underlying Platform View had
`PlatformViewHitTestBehavior.opaque` (the default). This changes it to
`PlatformViewHitTestBehavior.transparent` so the gestures are handled by
parent widgets.

Fixes https://github.com/flutter/flutter/issues/167398

Allow the Slider to always show the value indicator. (#162223)
Fixes: #34704

Modified enum `ShowValueIndicator`
before:
```dart
enum ShowValueIndicator {
  onlyForDiscrete,
  onlyForContinuous,
  always,
  never,
}
```
after:
```dart
enum ShowValueIndicator {
  onlyForDiscrete,
  onlyForContinuous,
  @Deprecated(
    'Use ShowValueIndicator.onDrag. '
    'This feature was deprecated after v3.28.0-1.0.pre.',
  )
  always,
  onDrag,
  alwaysVisible,
  never,
}
```
To maintain previous behavior, `ShowValueIndicator.onlyForDiscrete` and
`ShowValueIndicator.onlyForContinuous` are still retained.

The behavior of `ShowValueIndicator.always` remains consistent with the
previous implementation, but it is marked as deprecated and should be
replaced with `ShowValueIndicator.onDrag`. A new
`ShowValueIndicator.alwaysVisible` has been added to show the value
indicator even when not dragging.

Additionally, the value indicator is now rendered by `OverlayPortal`.

Change saturation calculation for HSLColor.fromColor (#166639)
<!--
Thanks for filing a pull request!
Reviewers are typically assigned within a week of filing a request.
To learn more about code review, see our documentation on Tree Hygiene:
https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md
-->

This pull request aligns the calculation of saturation for RGB to HSV
conversion with the common formulas you find on the
[internet](https://en.wikipedia.org/wiki/HSL_and_HSV#Saturation)
(concrete: if `r`, `g` and `b` are the same (-> gray), the saturation
should be 0).

This fixes black currently having a saturation of `1` instead of `0`. 

fixes #166460

This PR removes the logic about `_hadAtLeastOneListener`, a boolean to
check during `maybeDispose`. Although this check has existed when
disposal was first added, it was a weird logic without explanation, and
most importantly, removing it doesn't seem to break anything.

Add RoundedSuperellipseBorder and apply it to CupertinoActionSheet (#166303)
This PR creates a new class `RoundedSuperellipseBorder`, which is the
main way to draw a rounded superellipse with filling and/or stroking.

The new class is very similar to `RoundedRectangleBorder` and shares a
lot of private code, therefore they reside in the same file.

For demonstration purposes, the rounded superellipse is also applied to
`CupertinoActionSheet`, whose cancel button was drawn with the border
class.

(Sadly this demo wouldn't fit for dartpad because rounded superellipses
are not yet supported on Web.)

Add factory constructors for shorthands that would collide (#165597)
EdgeInsets and EdgeInsetsDirectional are subtypes of EdgeInsetsGeometry.
The both have only, all, and symmetric constructors, which creates
collisions in a world where Dart support shorthand notation such as:

```dart
Padding(
  padding: .only(bottom: 10.0),
),
```
 The same goes for all these classes: 

- AlignmentGeometry
  - Alignment
  - AlignmentDirectional
- BorderRadiusGeometry
  - BorderRadius
  - BorderRadiusDirectional
- BoxBorder
  - Border
  - BorderDirectional
- EdgeInsetsGeometry
  - EdgeInsets
  - EdgeInsetsDirectional


The shorthands feature is not planning to exhaustively check subtypes.
However, these classes were identified as the most impactful for the
shorthands feature ( ). Adding these factories in the super classes
enables future shorthand support.

Added semanticsIdentifier to Text Widgets (#163843)
This PR aims to add `semanticsIdentifier` to `Text` and some of its
internal objects to pass the semantics information for adding identifier
to the semantics nodes

From the issue filed at #163842, the following is a description of the
problem.

The [semantics
identifier](https://api.flutter.dev/flutter/semantics/SemanticsData/identifier.html)
helps in uniquely identifying elements using UI automation tools like
Appium, UIAutomator and XCUITests by setting identifiers that the screen
readers cannot see but the said tools can. This is especially useful
when working with a multi-lingual or multi-tenant app, where the element
IDs need to be unique but the content can be different. The `Semantics`
widget already has support for declaring it. However, the `Text` and
`Text.rich` variants only support setting `semanticsLabel` without
explicitly setting the identifiers. The widgets themselves can be
wrapped with a `Semantics` widget but it still does not cater for a rich
text that can have multiple text spans, each containing unique lables
and identifiers, and optionally gesture detectors for handling links.

Consider the following UI for two different tenants:
<img width="229" alt="Image"
src="https://github.com/user-attachments/assets/e8a24588-d94d-42fc-ba6c-ce39959207ae"
/>

Here, both the tenants utilise different strings to convey the same
message. The structure of the message stays the same so the identifiers
help in unifying the element identification process across the tenant
apps in the automation tools without having to write another script for
every other tenant.
Without the identifiers, the automation scripts require a rewrite per
tenant to be able to successfully locate the element and even tap on the
hyperlink.

# With PR Changes
## Appium Views
For the given sample code,
<details><summary>Text.rich Sample</summary>

```dart
Text.rich(
  TextSpan(
    text: 'This text contains both identifier and label.',
    semanticsLabel: 'Custom label',
    semanticsIdentifier: 'Custom identifier',
    style: customStyle1,
    children: <TextSpan>[
      TextSpan(
        text: ' While this one contains only label',
        semanticsLabel: 'Hello world',
        style: customStyle2,
      ),
      const TextSpan(
        text: ' and this contains only identifier,',
        semanticsIdentifier: 'Hello to the automation tool',
      ),
      TextSpan(
        text: ' this text contains neither identifier nor label.',
        style: customStyle2,
      ),
    ],
  ),
),
```
</details>
we have the following results with and without the PR code changes:

Check for a null codec in MultiFrameImageStreamCompleter after calling _emitFrame (#165009)
_emitFrame invokes image listeners. A listener callback could remove all
of the MultiFrameImageStreamCompleter's listeners, resulting in a
_maybeDispose call that destroys the codec.

fix: Dispose codec after completing frame creation (#159945)
ref https://github.com/flutter/flutter/issues/93404,
[comment](https://github.com/flutter/flutter/issues/93404#issuecomment-2525453113)
and
[comment](https://github.com/flutter/flutter/issues/93404#issuecomment-2547622795).

Added a process to call `ui.Codec`'s `dispose`.
With this change,
[HtmlBlobCodec](8e0993eda8/engine/src/flutter/lib/web_ui/lib/src/engine/html_image_element_codec.dart (L100))'s
dispose will be called in Safari when using CanvasKit, and
`revokeObjectURL` will be executed as expected.

* https://api.flutter.dev/flutter/dart-ui/Codec/dispose.html
* https://bugs.webkit.org/show_bug.cgi?id=31253
*
https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL_static
*
https://developer.mozilla.org/en-US/docs/Web/API/URL/revokeObjectURL_static

If this fix looks good, I will open the
https://github.com/flutter/flutter/pull/161481 to remove the
`AlearmClock` from the `BrowserImageDecoder`.

[Web] Allow specifying the strategy on when to use <img> element to display images (#159917)
This PR follows the discussion under
https://github.com/flutter/flutter/pull/157755 and adds a flag to
determine when `<img>` elements are used. By default the feature is
turned off.

Instead of just a boolean for on & off, I made it an enum to accept
multiple options. Notably, an `always` option can be useful when the
developer wants a unified experience regardless of the image origin
(such as when displaying an image from arbitrary URLs.)

Auto-format Framework (#160545)
This auto-formats all *.dart files in the repository outside of the
`engine` subdirectory and enforces that these files stay formatted with
a presubmit check.

**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the
commits one-by-one via the "Commits" tab and avoiding Github's "Files
changed" tab as it will likely slow down your browser because of the
size of this PR.

Adjust ignores for 'dart format' (#160382)
When running `dart format` over these lines the `// ignore` ended up on
a line where it wasn't properly ignoring the lint. This adjusts the
placement of `// ignore`s so they will continue to ignore the right
thing even after the code is auto formatted.

I am hoping that if we do this now the large PR that formats the entire
repo will go in smoother without manual intervention.

[web] On the web platform, use an <img> tag to show an image if it can't be accessed with CORS (#157755)
When using `Image.network`, if the given URL points to an image that is
cross-origin and not set up to allow CORS access, then we are unable to
make a [ui.Image] from it. In this case, render the image using a
platform view.

This is the last remaining checklist item for

Update color assertions (#154752)
issue: https://github.com/flutter/flutter/issues/127855
This is a forward fix to help
https://github.com/flutter/engine/pull/54981 land.

It makes the following changes:
1) Removes hardcoded `Color.toString()` assumptions in asserts
1) Switches some lerp tests to use numbers that are more friendly to
uint8_t and floating point numbers
1) implements custom matchers for color
1) removes word wrapping for some asserts since it makes them fragile to
changes in `Color.toString()` invocations
