[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.)

fix: time selector separator in timepicker is not centered vertically (#168441)
PR Description
This PR addresses an issue in the Flutter time picker where the
separator between the hour and minute selectors (:) was not centered
vertically. The change ensures that the separator is now vertically
centered, improving the overall UI alignment and consistency.

Previously, the separator used only the TextAlign.center property, which
did not fully address the vertical alignment issue. The updated code
wraps the separator text in a Center widget to ensure proper centering
both horizontally and vertically.

Before:

The separator (:) was horizontally centered but not aligned vertically.
After:

The separator is now both horizontally and vertically centered within
the time picker.

Fix DropdownMenu does not apply opacity to the selected value when disabled (#170336)
Fix https://github.com/flutter/flutter/issues/169942

### Description

The bug is about the
[effectiveTextStyle](b086fe7b79/packages/flutter/lib/src/material/dropdown_menu.dart (L979))
being applied to the inner
[TextField](b086fe7b79/packages/flutter/lib/src/material/dropdown_menu.dart (L1049))
inside DropdownMenu fails to reflect the disabled style based on the
[enabled
property](b086fe7b79/packages/flutter/lib/src/material/dropdown_menu.dart (L209)).
The fix for this is simply to check the `enabled` property and override
the TextField's TextStyle.

### Demo of the fix

Ensure disabling text fields' interactive selection disables shortcuts (#171050)
[`EditableText.enableInteractiveSelection`](https://api.flutter.dev/flutter/widgets/EditableText/enableInteractiveSelection.html)
can be used to disable text selection and shortcuts in a text field.

Previously, `EditableText` would disable the shortcut actions using
[`Action.isEnabled`](https://api.flutter.dev/flutter/widgets/Action/isEnabled.html).
As a result, the action would ignore the key event, and the key event
would propagate. On some platforms, the key event would propagate to the
native text view, causing weird behaviors like text getting copied.

Now, the text field shortcuts stop propagation of the key event when
`enableInteractiveSelection` is `false`. This ensures that the text
field "consumes" the key events and prevents a parent of the text field
or native views from receiving the key event.

Partially addresses https://github.com/flutter/flutter/issues/157611

⚠️ Note: This does not fix the bug on Flutter Web as it handles text
field shortcuts separately. This will be fixed in a separate pull
request.

NavigationRail: optionally scrollable and more configurable (#169421)
<!--
Thanks for filing a pull request!
Reviewers are typically assigned within a week of filing a request.

This is modified and extended version of the merged and reverted PR
#137415. It was reverted, because it broke a the sample app "Material 3
demo". This PR circumvents the breaking of existing code, by making the
changes optional via constructor parameters. Default values for the
parameters are functionally equivalent to the state before this change.
The new key parameter for this is `scrollable`.

Additionally this change includes the parameters `leadingAtTop: true`
and `trailingAtBottom: false`.

Fixes #89167

This is a reland of #166645

fixes #166642

**The newly added tests verify the following behaviors:**

1. DropdownButtonFormField can be focused if it was unfocused and we
replaced FocusNode.
2. DropdownButtonFormField can be unfocused if it was focused and we
replaced FocusNode.

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 PopupMenuButton unmounted exception when updating position (#166412)
<!--

https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md

This PR fixes an exception thrown when trying to update an unmounted
PopupMenuButton's position, which can happen when a layout change is
triggered during PopupMenuButton's pop animation (see issue's attached
video).
A workaround is to set `popUpAnimationStyle:
AnimationStyle.noAnimation`.
This PR fixes it by returning the last known position if the button is
unmounted.

Exception thrown:` FlutterError (This widget has been unmounted, so the
State no longer has a context (and should be considered defunct).
Consider canceling any active work during "dispose" or using the
"mounted" getter to determine if the State is still active.)`

Code that causes the exception: `final PopupMenuThemeData popupMenuTheme
= PopupMenuTheme.of(context);`

Fixes #163477 

Tested both on stable (3.29.2) and master (a0b1b325341)

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

**Fix text selection toolbar alignment for RTL (right-to-left)
languages**

This PR updates the Material text selection toolbar to properly support
right-to-left (RTL) layouts. Previously, the toolbar and its buttons did
not align or order correctly when using RTL text direction, leading to a
broken or confusing user experience for RTL languages.

**Summary of changes:**
- Refactored layout logic in `text_selection_toolbar.dart` to handle RTL
and LTR directions for both horizontal and overflow (vertical)
arrangements.
- Updated padding logic in `text_selection_toolbar_text_button.dart` to
use `EdgeInsetsDirectional`, ensuring correct padding for both text
directions.
- Added new widget tests to verify that:
  - Toolbar items are ordered right-to-left in RTL contexts.
- The overflow menu behaves correctly in RTL, showing items in the
correct order and position.

**Before:**  
- Toolbar items and overflow menus did not respect RTL layout, resulting
in misaligned or reversed button order.
- Padding was inconsistent in RTL.
<details>

|

</details>


**After:**  
- Toolbar items and overflow menus are correctly ordered and aligned for
RTL.
- Button padding is now directionally correct.

<details>
<summary>After Screenshots</summary>

This improves the usability and accessibility of text selection controls
for users of RTL languages.

Fix Radio's painters (#170321)
While working on https://github.com/flutter/flutter/issues/168787 as a
follow-up of https://github.com/flutter/flutter/pull/169415, I noticed
that the tests introduced in
https://github.com/flutter/flutter/pull/169415 were incorrect. However,
because of the way the `Radio` implements `paint` and reuses 1 painter,
it was not possible to properly assert the paints in the test.

This PR fixes it

Add back "Use live region in error text input decorator for Android #165531" (#168992)
Partly of https://github.com/flutter/flutter/issues/165510

⤴️ Parent PR: https://github.com/flutter/flutter/pull/169685 ( Merged)
⤴️ Parent PR (refactor): https://github.com/flutter/flutter/pull/170618
( Merged)

Re-lands https://github.com/flutter/flutter/pull/165531
The PR was originally reverted due to an issue with an internal Google
test. I added a new test case under `input_decorator_test.dart` which
does something similar to prevent the regression. All other code is the
same as https://github.com/flutter/flutter/pull/165531.

The easiest way to review this would probably be to just check the [diff
after the first
commit](cb5647c393)
to see the changes I made. To check if the reland commit is the same, it
might be best to just [compare solely that
commit](9bd8d5689b)
against the [original
PR](https://github.com/flutter/flutter/pull/165531/files).

Add RawMenuAnchor animation callbacks (#167806)
Alternative to https://github.com/flutter/flutter/pull/163481,
https://github.com/flutter/flutter/pull/167537,
https://github.com/flutter/flutter/pull/163481 that uses callbacks.

@dkwingsmt - you inspired me to simplify the menu behavior. I didn't end
up using Actions, mainly because nested behavior was unwieldy and
capturing BuildContext has drawbacks. This uses a basic callback
mechanism to animate the menu open and closed. Check out the examples.

<hr />

### The problem
RawMenuAnchor synchronously shows or hides an overlay menu in response
to `MenuController.open()` and `MenuController.close`, respectively.
Because animations cannot be run on a hidden overlay, there currently is
no way for developers to add animations to RawMenuAnchor and its
subclasses (MenuAnchor, DropdownMenuButton, etc).

### The solution
This PR:
- Adds two callbacks -- `onOpenRequested` and `onCloseRequested` -- to
RawMenuAnchor.
- onOpenRequested is called with a position and a showOverlay callback,
which opens the menu when called.
- onCloseRequested is called with a hideOverlay callback, which hides
the menu when called.

When `MenuController.open()` and `MenuController.close()` are called,
onOpenRequested and onCloseRequested are invoked, respectively.

Deprecate DropdownButtonFormField "value" parameter in favor of "initialValue" (#170805)
## Description

This PR renames the DropdownButtonFormField constuctor parameter 'value'
to 'initialValue'.
See
https://github.com/flutter/flutter/pull/170050#issuecomment-2965486000
and
https://github.com/flutter/flutter/pull/170050#issuecomment-2971920009
for some context.

## Related Issue

Fixes [DropdownButtonFormField retains selected value even after setting
value to null](https://github.com/flutter/flutter/issues/169983#top)

## Tests

Adds 2 tests (one to validate the deprecated parameter can still be
used, one for the dart fix).
Updates many (renaming the confusing parameter).

Normalize input decoration theme (#168981)
This PR is to make `InputDecorationTheme` conform to Flutter Material's
conventions for component themes:

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

```dart
InputDecorationTheme(
	data: InputDecorationThemeData(
	    filled: true,
	    fillColor: Colors.amber,
	    ...
	  ),
  	child: const TextField()
)
```
These two properties are made nullable to not break existing apps which
has customized `ThemeData.inputDecorationTheme`.

- Update `InputDecorationTheme` to be an `InheritedTheme` subclass.
- Changed the type of component theme defaults from
`InputDecorationTheme` to `InputDecorationThemeData`.
- Changed the `InputDecorationTheme bottomAppBarTheme` property to
`Object? bottomAppBarTheme` in `ThemeData` and `ThemeData.copyWith()`
(Object? is used for the moment to minimize Google tests failure. A
follow-up PR will replace `Object?` with `InputDecorationThemeData`.
- Addresses the "theme normalization" sub-project within #91772.

A migration guide will be created on website repo.

Normalize AppBarTheme (#169130)
This PR is to make `AppBarTheme` conform to Flutter Material's

- Added AppBarTheme constructor parameters: `AppBarThemeData? data` and

      child: Scaffold(
        appBar: AppBar(
          title: xxx,
          leading: xxx,
          actions: xxx,
     ),
),
```
These two properties are made nullable to not break existing apps which
has customized `ThemeData.appBarTheme`.

- Update `AppBarTheme` to be an `InheritedWidget` subclass.
- Changed the type of component theme defaults from `AppBarTheme` to
`AppBarThemeData`.
- Add new tests for `AppBarThemeData` and update the existing
`AppBarTheme` tests.
- This also temporarily changes `AppBarThemeData` to `Object?` in
`ThemeData` class, to bypass g3 tests, following
https://github.com/flutter/flutter/pull/168586#discussion_r2082606584.
- Addresses the "theme normalization" sub-project within
https://github.com/flutter/flutter/issues/91772.

Feat: Add mouse cursor for CupertinoDialogAction (#169051)
This PR updates the mouse pointer behavior for CupertinoDialogAction to
display a pointer cursor when hovering over the action button.
Currently, when hovering over CupertinoDialogAction buttons on desktop
platforms, the default cursor is shown instead of changing to a pointer
cursor, which doesn't provide proper visual feedback to users that the
element is clickable.

## Changes
- Added mouse cursor property to CupertinoDialogAction to display
SystemMouseCursors.click when hovering
- Updated relevant tests to verify the cursor behavior

## Technical Details
The implementation adds the appropriate cursor property to the
CupertinoDialogAction widget, ensuring that when users hover over the
action button on desktop platforms, the cursor changes to a pointer,
indicating that the element is clickable.

## Related Issues
fixes: #169037 (Mouse style doesn't change to pointer when hovering over
CupertinoDialogAction on Desktop)
Part of: #58192 (Add mouse cursor support to the remaining widgets)

CupertinoPicker new onChanged behaviour (#170202)
This PR adds a new behaviour to `ListWheelScrollView` that allows to
switch between reporting changes on scroll update or only on scroll end.
`CupertinoPicker` now has a `changeReportingBehavior` param that
forwards to `ListWheelScrollView`.

New behaviour is a breaking change if set as default, so I have added
the `changeReportingBehavior` param to opt-in. My idea is that it can be
marked as `Deprecated` immediately and then removed from
`CupertinoPicker` later or we can just leave the param there and make it
more customizable.

I am open to other ideas on how to land this without breaking clients.

Fixes https://github.com/flutter/flutter/issues/170201

fixes https://github.com/flutter/flutter/issues/170348

The root cause is the RawGestureDetector doesn't call individual ontap
method with correct position. A previous refactor to cupertinoButton
remove the onTap, but instead using the individual tap method to
register the click and surfaced this issue

Fix dragging scrollbar down causes unexpected behavior when scrollable has a negative minScrollExtent (#170331)

This PR fixed #170246.

In the original method for calculating the thumb position based on the
offset, the minimum scroll distance was assumed to be 0 by default,
which caused the scrollbar offset fraction to be constrained between 0
and 1. However, when minScrollExtent is negative, this range is
incorrect.

Modifications are listed below:
- The valid range has been updated to be between `minScrollExtent /
scrollableExtent` and `maxScrollExtent / scrollableExtent`.
- Added corresponding test cases for this change.
