Fix P3-to-sRGB color conversion to operate in linear light (#181720)
<!--
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
-->

### Problem
The P3-to-sRGB color conversion applies an affine matrix directly to
gamma-encoded values in both the C++ engine (`dl_color.cc`) and Dart
(`painting.dart`). This is mathematically incorrect — color space
conversion matrices must operate in linear light. The result is P3
colors that appear nearly identical to sRGB instead of showing the full
gamut difference.
For example, P3 `#1ECAD3` (30/255, 202/255, 211/255) converts to:
- **Old (wrong):** extendedSRGB (-0.12, 0.86, 0.87)
- **New (correct):** extendedSRGB (-0.38, 0.81, 0.84)
The red channel error of 0.26 is clearly visible — colors appear washed
out instead of vivid.

### Fix
Replace the single affine matrix multiply with the correct 3-step
pipeline:
1. **Linearize** — decode gamma via sRGB EOTF
2. **Transform** — apply 3x3 P3-to-sRGB matrix in linear space
3. **Encode** — re-apply gamma via sRGB OETF
Extended range (negative values from out-of-gamut colors) is handled by
mirroring the transfer function.
**C++ (`dl_color.cc`):** Replace affine matrix with `p3ToExtendedSrgb()`
using `double` precision.
**Dart (`painting.dart`):** Replace `_MatrixColorTransform` with
`_P3ToSrgbTransform` and `_SrgbToP3Transform` classes. Also fixes the
sRGB-to-P3 direction.

### Performance
Negligible. The C++ conversion runs once per paint setup in `ReadColor`,
not per frame or per pixel. The Dart conversion runs once per
`Color.withValues()` call.

### Tests
- **C++:** Added `ColorSpaceP3ToExtendedSRGBLinearLight` test in
`dl_color_unittests.cc`
- **Dart:** Added 3 tests in `colors_test.dart`: mid-range
P3→extendedSRGB, P3 green→extendedSRGB, sRGB→P3 round-trip
All new tests fail with the old code and pass with the fix. Existing
tests continue to pass.

[native assets] Split debug info into .dsym files (#181533)
This PR splits the debug info from code assets into separate dsym files
for MacOS and iOS.

The splitting only happens if the build mode is not debug. This aligns
with whether the debug symbols are separated out for the Flutter
framework and the app Framework.

Closes: https://github.com/flutter/flutter/issues/181377

Testing: Added some tests to the integration test

Enhance error handling of WidgetsBindingObserver callbacks (#181174)
<!--
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

Wraps all 16 WidgetsBindingObserver callback invocations in try-catch
blocks to prevent silent failures and ensure all observers are notified
even when one throws an exception.

Previously, exceptions in observer callbacks would either:
- Be silently discarded (method channel handlers)
- Prevent subsequent observers from being notified

Now, exceptions are properly reported via FlutterError.reportError and
all observers continue to receive notifications.

Fixes flutter/flutter#180434

Deprecate onReorder callback (#178242)
This pull request deprecates the old `onReorder` callback of
`ReorderableList` / `SliverReorderableList` / `ReorderableListView`, in
favor of a new callback, `onReorderItem`, that does the index correction
as mentioned in the docs at
https://api.flutter.dev/flutter/widgets/ReorderCallback.html

I added tests to ensure that the old callback is preferred when both are
provided and tests that assert that the new callback does the index
correction correctly. I also noticed that some tests used empty
callbacks for `onReorder`, those have been updated to use wildcards in a
consistent manner.

I did not opt into making a design doc, since the change itself is very
small, that will also be apparent in the migration guide that I am going
to write.

[hooks] Don't run build hooks for code assets in flutter run (#181542)
Since https://github.com/flutter/flutter/pull/174685, the code assets
are wrongly invoked on in the `flutter run` process (in addition to
rightly in the `flutter assemble` process). This should not be the case:
We don't know the target architectures we want to build for, neither do
we know which native compiler is set by the native build system that is
invoking us
(https://github.com/flutter/flutter/pull/181004#pullrequestreview-3664863551).

This PR changes the way the hooks are invoked:

* From `flutter run` only run for data assets. (Unblocks
https://github.com/flutter/flutter/pull/181004)
* All other remaining calls, run for both. There might be locations
where data assets could be disabled, but they are needed from the
`DartBuild` target at least in some cases.

The architecture becomes as follows:

* `FlutterNativeAssetsBuildRunner` this is basically the wrapper around
the `NativeAssetsBuildRunner` and there should be only one in a
`flutter_tools` instance, unchanged.
* `FlutterHookRunner` seems to be an interface to be able to supply
fakes, unchanged.
* `runFlutterSpecificHooks` get bool arguments whether they should build
code assets and data assets.
* The callers of these APIs know what asset types are needed in that
context. The invocations added in
https://github.com/flutter/flutter/pull/174685 should be data assets
only.
* Simplification: `FlutterHookRunnerNative.runHooks` does no longer use
`globals.buildSystem.build`. Instead, it directly calls
`runFlutterSpecificHooks`.
* This completely avoids writing to the flutter build directory, which
was the cause of https://github.com/flutter/flutter/issues/178529.
* The `ProtocolExtension`s (which determine which asset types are built)
are taken from `AssetBuildTarget`s, and take into account what asset
types to build, unchanged.

Tests:

* Code assets covered by existing integration tests such as
packages/flutter_tools/test/integration.shard/isolated/native_assets_test.dart
* Data assets covered by existing integration tests such as
packages/flutter_tools/test/integration.shard/isolated/dart_data_asset_test.dart
* This PR completely deletes
packages/flutter_tools/test/general.shard/build_system/targets/hook_runner_native_test.dart.
It was a unit test that testsed the specific workaround, not the effect
of the workaround.
* I've manually tested the steps in
https://github.com/flutter/flutter/issues/178529#issuecomment-3542651915,
the issue does not come back.
  
> the underlying issue did involve conflict between state written by the
original run of the build system versus state written by the secondary
run executed for the data assets. If the secondary run can be avoided,
then that seems cleaner.

Yep, removed.

Add isDark, isLight, and isSystem getters to ThemeMode (#181475)
Adds boolean convenience getters (`isDark`, `isLight`, `isSystem`) to
`ThemeMode`.

This change improves readability and ergonomics when branching on
`ThemeMode` values by
providing named, self-documenting getters instead of repeated equality
checks
(e.g. `themeMode == ThemeMode.dark`). The addition is non-breaking and
does not
change any existing behavior.

Example:

Before:
if (themeMode == ThemeMode.dark) {
  ...
}

After:
if (themeMode.isDark) {
  ...
}

No tests were added as this change introduces simple enum getters with
no logic
beyond value comparison and does not alter runtime behavior.

[material/menu_anchor.dart] Add animations to MenuAnchor. (#176494)
* Adds MD3 animations to MenuAnchor. 
* Adds a "hoverOpenDelay" parameter on `SubmenuButton`
* Moves the layout algorithm from SingleChildLayoutDelegate to a custom
render object. <s>This was done because I needed to access the dry
layout of the menu panel for the best effect. I'll demonstrate
below.</s> Turns out using dry layout significantly limits what children
you can use with a widget. As a result, I'm calculating the final height
using the inverse height factor.

Fixes https://github.com/flutter/flutter/issues/135025

I don't have access to the internal Google documentation, so I did my
best to deduce the spec from
https://github.com/material-components/material-web/blob/main/menu/internal/menu.ts.

This change is currently opt-in via an `animated` parameter on
`MenuAnchor` and `SubmenuButton`. As a result, this is not a breaking
change. Because the PR is already quite large, I chose to not add
animation customization to this PR. I also didn't change any theming
files or `DropdownMenu`.

The only other API addition is a `hoverOpenDelay` parameter on
`SubmenuButton`. This parameter delays the start of a submenu opening by
the specified duration. It is independent of the `animated` parameter.

When `animated == false`, the menu runs its forward and reverse
animations with a duration of 0. I originally disposed of all animation
assets when `animated` was false, but found that the code/testing
complexity to be unwieldy.

<s>Blocked by https://github.com/flutter/flutter/pull/176503</s>

Send statusBarTouch events via dedicated messages (#179643)
Instead of using fake touch events. 

Before this patch `FlutterViewController` sends two fake touch events
(down and up), at `(0, 0)` to the framework to signal that the status
bar is tapped on iOS. The scaffold widget and the cupertino page
scaffold widget set up gesture detectors to listen for these fake taps,
and scroll the "primary" scrollable container to the top in response.

This messaging mechanism is sometimes ambiguous, as the framework may
interpret that as a pair of regular pointer tap events (for instance in
#177992 the modal barrier claims the tap gesture and as a result the
modal barrier is dismissed by the fake touch events). This PR changes
that to communicate the status bar tap event via a new system channel,
and dispatch the events via `WidgetsBindingObserver`s in the framework.

See also
https://github.com/flutter/flutter/issues/177992#issuecomment-3499913265

Fixes #177992, fixes #175606

It appears that UIKit also has access to the coordinates of the touch
events to determine which scrollable view(s?) to dispatch the scroll to
top event to.
```objc
  * frame #0: 0x00000001032f6520 UIPlayground.debug.dylib`MyScrollViewController.scrollViewShouldScrollToTop(scrollView=0x0000000106014800) at UIScrollView.swift:13:3

    frame #7: 0x000000018581eb60 UIKitCore`-[UIStatusBarManager handleTapAction:] + 60
```
Unfortunately that information is not available to user application. The
iOS accessibility bridge currently does create dummy UIScrollViews for
each scrollable in the accessibility tree so may be we can take
advantage of that in the future.

test: Improve DropdownMenuFormField tests (#181369)
Resolves
https://github.com/flutter/flutter/pull/181367#discussion_r2719670803

The test was still valid as `DropdownMenuFormField` includes
`DropdownMenu` and therefore could select the desired MenuItemButton.

Fix todayBorder todayBorder color is incorrectly overridden by todayForegroundColor in CalendarDatePicker (#178792)
- Fix https://github.com/flutter/flutter/issues/177911
- In this PR:
- Avoid auto-overriding border side color with `dayForegroundColor` when
users specify an explicit border color
    - Improve `todayBorder` documentation to clarify cases can happen.
- Add an opacity check: this is because if we don't respect/specify an
explicit border color, we still need to keep enabled/disabled states
(state-aware) that `dayForegroundColor` always does:


de3f804590/packages/flutter/lib/src/material/date_picker_theme.dart (L1174)

So we need a fallback compatibility here:

```dart
final bool hasCustomBorderColor =
        datePickerTheme.todayBorder != null && datePickerTheme.todayBorder?.color.opacity != 0.0;
    final BorderSide todayBorderSide = hasCustomBorderColor
        ? datePickerTheme.todayBorder!
        : (datePickerTheme.todayBorder ?? defaults.todayBorder!).copyWith(
            color: dayForegroundColor,
          );
```

- Added 3 tests in `calendar_date_picker_test.dart‎`.
- Update test data in `date_picker_theme_test.dart`: Updated todayBorder
from `BorderSide(width: 3)` to `BorderSide(width: 3, color:
Color(0x00000000))` to maintain backward compatible behavior in tests:
after changing color to transparent, it should fall back to
`todayForegroundColor`. This is because the test's real purpose was to
verify theme properties work, and it was expecting foreground color
(which is the bug reported).

Extracted from https://github.com/flutter/flutter/pull/176968 in an

This just adds a custom error message to all asserts on the `Gesture
details debugFillProperties` test, making it clear _which_ event broke
the test. While we don't expect tests to break, while developing, this
can save several minutes of guesswork.

[Material] modernize time picker components with Dart 3 switch expressions (#181356)
Following up on #181041, I took another look at `time_picker.dart` for
any remaining switch statements that could be modernized.

I found that `_timeSelectorSeparatorValue` and the `height` calculation
in `_TimeSelectorSeparator` were great candidates. By using logical OR
patterns and inlining the assignments, I was able to convert them into
clean switch expressions. The logic remains exactly the same, but the
boilerplate is gone.

[Reland] Don't strip symbols from libapp.so on android by default (#181275)
Relands https://github.com/flutter/flutter/pull/162464
Fixes https://github.com/flutter/flutter/issues/170664

The only test that failed last time was `Linux_pixel_7pro
android_obfuscate_test`, and I ran it locally (`flutter test
test/integration.shard/android_obfuscate_test.dart `) to both repro the
failure and verify it passes on this branch with the additional changes.

Also does some stuff in the FGP:

The reason we failed the tests last time was we were bundling of the
libapp.so code into a jar in the aar case, instead of simply including
it as its own file in the source sets. I let gemini go on that part,
modifying it to no longer pack as a jar, but it looks correct to me. Now
that the `libapp.so` file is simply included in this case, AGP is able
to strip it (it's not hidden inside a jar).

Because this changes the FGP build process for add to app, I manually
verified that the add to app flow isn't broken for including a flutter
module both as source and as an aar.

<details>
  <summary>Before and after logs from the gradle task output</summary>
  
Before:
```
                     > Task :flutter:stripReleaseDebugSymbols NO-SOURCE
                     Skipping task ':flutter:stripReleaseDebugSymbols' as it has no source files and no previous output files.
```

After:

```
                    Task ':flutter:stripReleaseDebugSymbols' is not up-to-date because:
                       No history is available.
                     The input changes require a full rebuild for incremental task ':flutter:stripReleaseDebugSymbols'.

[Material] modernize Typography._withPlatform with Dart 3 switch expression (#181398)
Continuing the effort to clean up some of the older switch statements,
I've moved over to `typography.dart`

I found that `Typography._withPlatform` was using a standard switch
block to handle platform-specific theme assignments. Since both `black`
and `white` themes are resolved based on the same platform variable,
I've refactored this into a single switch expression using a Record.
This allowed me to group Android and Fuchsia together using the new
logical OR pattern, which feels much cleaner.

The logic and the existing fallbacks haven't changed at all—the `assert`
at the start already guarantees we have the required themes if the
platform is null, so I've handled that case directly in the expression.

I've run the local tests in `typography_test.dart` and everything is
passing.

CupertinoSheetRoute with scrolling and dragging (#177337)
Fixes #161687

Enables scrollable content within the sheet to work together with the
dragging animation.

Flutter:


https://github.com/user-attachments/assets/3a9994e3-078a-410e-8288-95592713ab39



Native:


https://github.com/user-attachments/assets/c0bd46fb-26f5-41a6-bf42-6c78c23ddf34

Fling when scrolling to the top vs fling when the scrollable content is
already at the top


https://github.com/user-attachments/assets/e934facc-36d2-4e81-9ccd-a3e9dd7b6201



When scrolling is enabled, then the sheet will no longer have a drag
gesture recognizer over the sheet content, and will instead rely on the
scrollable content to trigger the drag. A non-scrolling area can be
wrapped with `CupertinoSheetDragArea` to put a drag gesture recognizer
only on that area, convenient for navbars. See
[cupertino_sheet.3.dart](https://github.com/flutter/flutter/pull/177337/files#diff-3df71aa5e6ddb6184007a85e847a9a4883515697b7014764e1978d240d72e0e1)
for a full example.

Look for project root for FeatureFlags manifest (#180689)
Fixes #176294.

The `FeatureFlags` service is now instantiated with the manifest parsed
not from `<current working directory>/pubspec.yaml`, but from
`findProjectRoot(cwd)` (falling back to old behavior).

Remove the Material import from sliver_visibility_test.dart since it's
only testing SliverVisibility, a widgets-level component. The test
doesn't need Material-specific functionality - it only uses
DefaultWidgetsLocalizations.delegate which provides sufficient
localization support.

Changes:
- Replaced `import 'package:flutter/material.dart'` with `import
'package:flutter/widgets.dart'`
- Removed `DefaultMaterialLocalizations.delegate` from the localizations
delegates list

This helps with the decoupling of Material and Cupertino from the core
framework.

Add bottom navigation bar item semantics label (#180577)
Fix [#180621](https://github.com/flutter/flutter/issues/180621)

This PR adds a semanticsLabel for the BottomNavigationBarItem.



While this PR addresses the need for a semanticsLabel, it's worth noting
that replacing the current "String label" parameter with a "Widget
label" could be a more flexible long-term solution in the
BottomNavigationBarItem. This approach would allow full control over the
label's content and appearance.

However, this would be a breaking change.
