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`.

Make DropdownMenu TextField reactive to label changes (#162062)
## Description

The current behavior of Flutter regarding `DropdownMenu` text field is
very basic: `DropdownMenu` updates the text field once a selection has
been made with its coordinating `label`, and nothing more.

If the selection's `label` changes, the text field will still show the
old value, although the menu buttons have been updated.

This not only results in the need to write a lot of boilerplate code to
match the label to the current selection, but it's also
counterintuitive. The `DropdownMenu` should handle rematching by itself.

Issue #155660, touched on this, and a solution was introduced in
#155757. It was later reverted due to it restricting some use cases.
That issue & solution, however, only address `initialSelection`. If
another selection was made and its corresponding `label` was changed,
the text field would still show the old value, bringing us back to
square one.

This PR should not conflict with any previous behavior of
`DropdownMenu`: any new value provided by `initialSelection` or via
controller would not be overwritten by rematching. However, entries with
the same value will be mapped to a single label (the first matched
entry's label).

## Related Issues

- Fixes #155660.

## Tests

Added 3 tests.

Fix date picker calendar tap targets (portrait mode) (#169163)
## Description

This PR fixes the touch target (and Semantic bounds) for day buttons
shown in the date picker calendar mode.
To do so it changes the dialog size and buttons padding to conform to
the M3 spec, see
https://m3.material.io/components/date-pickers/specs#2d53890e-a08f-4c63-a0d9-abd9e95b4245

### Before

### After


![image](https://github.com/user-attachments/assets/83fd37e2-2cd1-454d-a13d-f2dcc3220e3b)

## Related Issue

Fixes [DateTimePicker date buttons fail touch target size accessibility
checks](https://github.com/flutter/flutter/issues/158325)

## Tests

Adds 1 test.

## Implementation choice

This PR targets only M3 and portrait mode:
- M3 because M2 dialog picker was not designed to be accessible (day
buttons are 40 pixels).
- Portrait mode only, because there are no specification for the
landscape mode and existing implementations (Google Calendar, Compose)
vary. I will open a separate issue to discuss a possible solution for
landscape mode.

previous https://github.com/flutter/flutter/pull/167363

I have to factor out abstract class for RadioGroupRegistry and
RadioClient which are subclassed by RadioGroupState and RawRadio
respectively.

I have to do this because the RadioListTile that has 2 focusnode one for
listTile and one for the radio it builds. The issue is that RadioGroup's
keyboard shortcut has to tightly couples with the focus node of each
radio, but the radioListtile has to mute the radio's focusnode so it can
act as one control under keyboard shortcut

d582b35809/packages/flutter/lib/src/material/radio_list_tile.dart (L484)

Therefore i abstract the out the logic of RadioGroup so that another
widget can participate by implementing the interface.

Revert "Fix NavigationBar indicator overlay color (#164484)" (#169497)
## Description

This PR reverts the change from [Fix NavigationBar indicator overlay
color](https://github.com/flutter/flutter/pull/164484) as it leads to
several regressions.

The change was very small: replacing a Container (which obscured the
overlay) with an Ink. Unfortunately this leads to some rendering issues
which seem related to the Ink painting not being fully in sync with the
animation logic implemented by `NavigationIndicator`.
I investigated this but did not find an obvious solution. So I would
prefer to revert https://github.com/flutter/flutter/pull/164484 as the
issue it fixed has less impact than the regression.
cc @justinmc for review and also in case you have some clue about why an
Ink would cause such problems compared to a Container.

[Cupertino] Apply RSuperellipse to most Cupertino widgets (#167784)
This PR applies RSuperellipse to most Cupertino widgets. I got the list
by searching for `ClipRRect`, `drawRRect`, and `BoxDecoration` (with
`borderRadius`) through the package. They're replaced by
`ClipRSuperellipse`, `drawRSuperellipse`, and `ShapeDecoration`
respectively.

There are a few widgets that I didn't apply:
* `CupertinoTextField` as well as its related widget
`CupertinoSearchTextField`, because `CupertinoTextField` expects a
`BoxDecoration` argument. Migrating it is nontrivial and will take place
in a separate PR.
* `CupertinoTextSelectionToolbar`, because it seems complicated
(containing a lot of paths). I wonder if it's possible to replace the
clipPath with clipRRect/clipRSe for better performance.
* `CupertinoSwitch`. I suspect it's not an squircle since it tightly
contains a full circle.

Fixes https://github.com/flutter/flutter/issues/13914.

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

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.

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:

Use live region in error text input decorator for Android (#165531)
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.

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`.

### Demo the fix

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

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)
<!--

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.

This commit introduces a `maxWidth` property to `Dialog` to allow
limiting the maximum width of the component. It is following the
[Material3
guidelines](https://m3.material.io/components/dialogs/specs#6771d107-624e-47cc-b6d8-2b7b620ba2f1)
for Dialogs

No tests have been created yet. I'd like to get feedback on the
implementation approach before writing tests to ensure they are aligned
with the intended design

Issue: https://github.com/flutter/flutter/issues/163709
