Fix crash on two finger selection gesture (#168598)
This change blocks two selection handles from being able to be dragged
simultaneously on iOS and the web, this matches the native behavior. On
native Android both handles can still be dragged simultaneously this is
the behavior observed on Google Keep/ Google Messages and Android's
EditText.

Also fixes an issue on iOS where the magnifier would not return after
hiding when double tapping and dragging to select and then dragging
outside the TextField area. The cause of this issue was because
editableText.showMagnifier decides whether to update the magnifier
position or show a new one based on whether it was visible, so when it
was hidden and we attempt to update it's position, it would try to show
a new magnifier which left the magnifier in a broken state. This change
makes editableText.showMagnifier depend on whether a magnifier exists
instead of just checking it's visibility. Similarly
editableText.hideMagnifier now does not depend on the magnifier
visibility, instead it internally (selectionOverlay.hideMagnifier)
checks if the magnifier exists.

Fixes #168578

fixes https://github.com/flutter/flutter/issues/169175

the bug is due to the image widget will create it own semanitc node and
force the semantics widget in the stack to form its own node instead of
merge up. Modify the code so that it works correctly.

Respect calendarDelegate in showDateRangePicker (#168290)
This PR fixes an issue where the `calendarDelegate` parameter was not
respected by `showDateRangePicker`. Although support
for`calendarDelegate` was added in [PR
#161874](https://github.com/flutter/flutter/pull/161874), it was
inadvertently omitted from `showDateRangePicker`, causing
inconsistencies in behavior compared to `showDatePicker`.

Shared element transition for predictive back (#154718)
This PR adds a shared element transition for predictive back navigation,
based on the specification found here:
https://developer.android.com/design/ui/mobile/guides/patterns/predictive-back#shared-element-transition.

A new transition builder added:
`PredictiveBackPageSharedElementTransitionsBuilder`, which constructs
the shared element transition version.

<details><summary>Code sample</summary>

```dart
import 'package:flutter/material.dart';

void main() {
  runApp(const MainApp());
}

class MainApp extends StatelessWidget {
  const MainApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(
        brightness: Brightness.light,
        pageTransitionsTheme: const PageTransitionsTheme(
          builders: {
            TargetPlatform.android: PredictiveBackPageSharedElementTransitionsBuilder(),
          },
        ),
      ),
      home: const FirstScreen(),
    );
  }
}

class FirstScreen extends StatelessWidget {
  const FirstScreen({super.key});

  @override

          },
          child: const Text('Go to Second Screen'),

Resolve Cupertino textstyle in MaterialBasedCupertinoThemeData (#167597)
Fixes #146864. The overridden resolve was keeping the Cupertino text
styles from resolving their dynamic colors depending on the theme
brightness when in a MaterialApp in most cases. I *believe* that this
was to keep values from the Material theme from changing, but as far as
I can tell that shouldn't affect anything in the current state and that
is 6 year old code. Waiting to see if tests make me a liar.

Update: tests made me a liar.

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.

Normalize BottomAppBarTheme (#168586)
This PR is to make `BottomAppBarTheme` conform to Flutter Material's
conventions for component themes:

- Added a `BottomAppBarThemeData` class which defines overrides for the
defaults for `BottomAppBar` properties.
- Added `BottomAppBarTheme` constructor parameters:
`BottomAppBarThemeData? data` and `Widget? child`. This is now the
preferred way to configure a `BottomAppBarTheme`:

```dart
BottomAppBarTheme(
	data: BottomAppBarThemeData(
	    color: xxx,
	    height: xxx,
	    elevation: xxx,
	    shape: xxx,
	    ...
	  ),
  	child: const BottomAppBar()
)
```
These two properties are made nullable to not break existing apps which
has customized `ThemeData.bottomAppBarTheme`.

- Update `BottomAppBarTheme` to be an `InheritedWidget` subclass.
- Changed the type of component theme defaults from `BottomAppBarTheme`
to `BottomAppBarThemeData`.
- Changed the `BottomAppBarTheme bottomAppBarTheme` property to
`BottomAppBarThemeData bottomAppBarTheme` in `ThemeData` and
`ThemeData.copyWith()`. This may cause breaking changes, a migration
guide will be created on website repo.
- Add new tests for `BottomAppBarThemeData` and update the existing
`BottomAppBarTheme` tests. And also turn to `true` for `useMaterial3`
(along with usages accordingly) at the common method `_withTheme()`
since `useMaterial3` is true by default.
- Addresses the "theme normalization" sub-project within #91772.

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:

Make the barrier panel on the Material Drawer non-dismissible (#164810)
This PR entails making the modal barrier behind the Material Drawer
dismissible / non-dismissible via a Scaffold flag named
"drawerBarrierDismissible", as in:

```
Scaffold(
   drawerBarrierDismissible: false, // defaults to true so it behaves as normal
   ....
)
```

This is so as to force the Drawer to be opened / closed programmatically
using either:

```
Scaffold.of(context).openEndDrawer() / openDrawer()
```

or 

```
Scaffold.of(Utils.adminNav.currentContext!).closeDrawer() / closeEndDrawer()
```

and the user not closing the Drawer upon tapping on the modal barrier.

Fix Selected DropdownMenuItem isn't highlighted on mobile (#167874)
Fix https://github.com/flutter/flutter/issues/70294

### Description

The bug is about the previously selected DropdownMenuItem isn't
highlighted on mobile while it works on Web and desktop. The reason is
that `FocusManager.instance.highlightMode` has fallen to
`FocusHighlightMode.touch` on mobile by default (or touch device without
mouse in general):


6f220d3ec0/packages/flutter/lib/src/material/dropdown.dart (L172-L175)


7d56be4c8d/packages/flutter/lib/src/widgets/focus_manager.dart (L2335-L2353)


7d56be4c8d/packages/flutter/lib/src/widgets/focus_manager.dart (L1741-L1748)

We actually can work around this by setting
`FocusManager.instance.highlightStrategy` to
`FocusHighlightStrategy.alwaysTraditional`, see
https://github.com/flutter/flutter/pull/70442#issuecomment-727036571.
Nevertheless, this approach will may affect the entire scope of the app,
potentially resulting in unforeseen behavior for other widgets. 

In this PR, I propose a straightforward solution that utilizes an
ancestor widget (Ink) to manage the color state corresponding to
`InkWell.overlayColor`.

Fix ListTile overwriting parent IconButtonTheme for its children (#167727) (#168480)
### Description

ListTile was recreating its own IconButtonThemeData—discarding any
styles inherited from an existing IconButtonTheme above it. This change
makes ListTile merge its theme data with the inherited one instead of
replacing it, so child IconButtons now correctly pick up parent styling

issue: https://github.com/flutter/flutter/issues/167727

Add option to hide trailing icon in DropdownMenu (#167782)
This PR adds support for hiding the trailing icon in `DropdownMenu`
widget. Currently, there's no built-in option to remove it.

The change is non-breaking, as the trailing icon remains visible by
default unless `showTrailingIcon` is explicitly set to `false`. The
`showTrailingIcon` parameter follows a similar pattern to its use in the
`ExpansionTile` widget.

Fixes #164908

InputDecorator - animate between transparent hoverColor and hoverColor (#168244)
<!--
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
-->

As described in https://github.com/flutter/flutter/issues/155169,
TextFields with hoverColor set can have an issue where they flicker as
the mouse enters and exits their bounds.

_BorderContainerState uses a 15ms animation to transition between
non-hovered and hovered states. Part of this animation is a ColorTween
between Colors.transparent and a given hoverColor. Critically,
Colors.transparent is transparent black. On high refresh rate displays
(any display with faster than 60z), this can result in a frame being
rendered where the TextField fill color is a dark, semi-transparent
version of hoverColor.

The immediate solution to this is to animate between hoverColor and a
hoverColor with alpha 0.

Highlighting hour and minute input fields (#167766)
<!--
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 PR addresses the issue in time_picker.dart where pressing the TAB
key to navigate between the hour and minute fields in input mode doesn't
properly select the text in the newly focused field.

**What Changed**

- Added focus traversal logic in the _HourMinuteTextFieldState class's
initState method that:

1. Properly handles TAB key presses to move focus to the next field
2. Automatically selects all text when a field gains focus

- Added tests in time_picker_test.dart to verify that:

1. The hour field's text is selected when it gains focus
2. Pressing TAB moves focus to the minute field
3. The minute field's text is selected when it receives focus via TAB
key

**Why This Matters**
This change improves accessibility and usability of the time picker in
input mode. When users navigate using the keyboard (pressing TAB), they
expect the text in the newly focused field to be fully selected,
allowing them to immediately type a new value without having to manually
delete the existing text. This is standard behavior in form fields and
now the TimePicker component follows this expected pattern.

This PR exposes `borderOnForeground` from the `Material` class to
`ButtonStyle` and `OutlinedButton` class, letting the developer decide
whether to show the border on foreground or background.

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.
