Fix(Material): DateRangePicker ignores DatePickerTheme.dayShape (#181658)

This change fixes a problem where `showDateRangePicker` ignored the
`dayShape` property in `DatePickerThemeData`, leading to days always
rendering as circles regardless of the theme. This was caused by the
internal `_DayItem` widget using a hardcoded `BoxDecoration` regardless
of the theme configuration.

Fixes #181500

[web] Pass form validation errors to screen readers via aria-description (#180556)
Fixes part of #180496

## Summary
Pass form validation errors to screen readers via `aria-description` on
text fields.

**Before:** 
https://flutter-demo-04-before.web.app/

**After:** 
https://flutter-demo-04-after.web.app/

## Limitations & Future Work

This handles **string-based errors** (`errorText`). For more complex
cases(brought in
https://github.com/flutter/flutter/issues/180496#issuecomment-3713178684),
a follow-up implementation using `aria-describedby` with element IDs is
tracked in #180496:

- Custom error widgets (`InputDecoration.error`)
- Errors outside `InputDecoration`
- Custom announcement ordering

The `aria-description` approach (current) and `aria-describedby`
approach (future) can coexist per ARIA specifications.

[a11y] RangeSlider mouse interaction should change keyboard focus (#182185)
fix: https://github.com/flutter/flutter/issues/173575 

RangeSlider manages its own focus node for 2 thumbs. ( a special case
because it's one widget, one render object but two focus nodes)

so when you dragging a thumb, or tap a thumb, the focus node should
request focus.

Do not wait until dispose before removing replaced/popped page (#182315)
Regression was introduced in [Cleans up navigator pop and remove
logic](https://github.com/flutter/flutter/pull/175612/changes#top).

That PR moved the `onDidRemovePage` call to `_flushHistoryUpdates` in
phase `_RouteLifecycle.dispose`. But waiting until `dispose` causes
potential problems if the widget is rebuilt in a phase preceding that
(but after `pop` or `pushReplacement` has been called). So the outdated
page remains in the pages list even after it has been marked for
removal.

This is causing the page to be pushed again before it is finally
removed, causing the flicker.

Add contentTextStyle support to SimpleDialog (#178824)
## Description

This PR adds `contentTextStyle` support to `SimpleDialog`, matching the
functionality already available in `AlertDialog`.

### Problem

`SimpleDialog` was ignoring `DialogTheme.contentTextStyle`, even though
the `DialogThemeData.contentTextStyle` documentation explicitly states
it applies to `SimpleDialog.children`:

> "Overrides the default value for DefaultTextStyle for
SimpleDialog.children and AlertDialog.content."

However, only `AlertDialog` actually implemented this behavior, forcing
developers to specify text styles individually on each child widget.

### Solution

Added `contentTextStyle` parameter to `SimpleDialog` and applied it
using `DefaultTextStyle`, following the same pattern as `AlertDialog`.
The implementation uses the standard fallback chain:

`contentTextStyle` parameter → `DialogTheme.contentTextStyle` → M2/M3
defaults

### Testing

Added a new test `'SimpleDialog Custom Content Text Style'` that
verifies `contentTextStyle` is correctly applied to the children of
`SimpleDialog`.

[Web] Fix IME and selection by syncing more text styles (#180436)
fix https://github.com/flutter/flutter/issues/161592

The current implementation does not fully reflect
[letter-spacing](https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/letter-spacing),
[word-spacing](https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/word-spacing),

in the DOM. 0bc99f8c4f70973a1877c88ca35804e9bc5fabcf
And the current implementation generates an DomHTMLTextAreaElement every
time the `enabled`. Therefore, it reapplies the
[scrollTop](https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollTop)
value that the Element had been holding internally.

When a scrollable handles a wheel event, it now calls

In iframe mode, the engine always calls preventDefault() to block native
scroll chaining, then uses postMessage to explicitly scroll the parent

Mark all IconData fields as entrypoints to prevent tree shaking its fields (#181849)
Flutter's tree shaking of icon data in fonts examines the tree shaken
Kernel AST, searching for `IconData` constants. It will then examine
their fields in order to shake parts of fonts.

We should mark those fields as entrypoints to prevent the tree shaker
from removing the fields (an optimization that may land in [0]) as the
`const_finder` tool relies on them being there.

Make HCPP upgrading work for vd/tlhc (#181024)
Before the change we get a NPE when trying to cast the return of the
create message as an int.

There are also some more changes needed on top of the change to the
cast, making the `TextureAndroidViewController` aware of if it is using
HCPP and exposing that bool for use in
`packages/flutter/lib/src/rendering/platform_view.dart`

This is untested because it currently isn't possible to use HCPP without
uncommenting the code block here:
2beceb6b1c/engine/src/flutter/shell/platform/android/io/flutter/embedding/engine/systemchannels/PlatformViewsChannel.java (L95)

It will be tested in the follow up pr which adds the cli flag,
uncomments the block, and adds golden tests that we can upgrade each of
the 3 legacy modes.

Fixes https://github.com/flutter/flutter/issues/181000

Disable hardware keyboard regularity warning by default (#181894)
Suppresses https://github.com/flutter/flutter/issues/125975

This PR disable hardware keyboard regularity warning unless
`debugPrintKeyboardEvents` is set.

Keyboard state synchronization has proven extremely difficult, largely
due to the asynchronous communication between the engine and framework.
Unfortunately, I haven't had the bandwidth to fix it, causing developers
to experience false errors during hot restarts. It's time to acknowledge
this and prioritize development experience over idealism by disabling
these useless warnings.

I apologize for the issues I've caused over the years. Perhaps someday
we can make this work with a fully regular event stream.

Propagates Overlay's MediaQueryData to OverlayPortal child (#181579)
Widgets like Scaffold strip MediaQueryData causing widgets rendered in
the Overlay to be obscured, e.g., by the software keyboard.

[Related Issue -
142921](https://github.com/flutter/flutter/issues/142921)
[Related Issue -
157664](https://github.com/flutter/flutter/issues/157664)

This does not directly fix these two issues but appears to be an
underlying issue with both which merited this being a separate PR. I
have a separate fix for the MenuAnchor that I will supply in a follow up
PR.

Fix decorated box (#179802)
Fix #179801

`RenderSliver.getMaxPaintRect` was moved up to `RenderSliver` as it is
also needed for PR #179003, the logic was therefore duplicated here.

(The widget labeled `A SliverToBoxAdapter` is actually a
`PinnedHeaderSliver`)

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

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.

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.

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>

## Examples

* Basic example adapted from material-web

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.

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).

[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.

Fix Range Slider issue where indescrete ranges lead to out of range r… (#181082)
*These change fixes a problem when during a drag that took the
minThumbSepartionValue into account led to a value outside of the
allowed range of (0.0, 1.0) which caused a exception in rebuild where
assert is used to check for that range.*

Fixes issue #180984 

*If you had to change anything in the [flutter/tests] repo, include a
link to the migration guide as per the [breaking change policy].*
