Currently on iOS `TextField` horizontal drag gestures will have precedence over parent horizontal drag gestures when competing with each other because the default `touchSlop` value used by `TextField` to calculate whether the threshold for a drag has been met is the same as the one used by parent horizontal drag gestures like `PageView`, and other `Scrollable`s. The default value is `18.0`, and because the `TextField` receives the `PointerEvent` first in this scenario, it always declares victory before any parent horizontal drag gestures has the chance to.
Native iOS behavior: The parent horizontal drag gestures will always win unless the drag originated on the cursor (collapsed selection), in that case the TextField cursor drag gestures will win.
This change:
* Introduces `BaseTapAndDragGestureRecognizer.eagerVictoryOnDrag` which can be used to configure the recognizer to declare victory immediately when it detects a drag, or when disabled it will wait until it is the last recognizer in the arena before declaring victory. The default behavior is that it declares victory immediately when the drag is detected.
* Eliminates the iOS cursor drag logic from `TextSelectionGestureDetector`, this logic is now delegated to the selection handle overlay which already had this logic in place.
* Enables iOS cursor to always beat other drag gestures by setting the touch slop lower.
* Disables `eagerVictoryOnDrag` for iOS to allow for parent drag gestures to win and match native behavior.

Part of https://github.com/flutter/flutter/issues/141198
## Description
This PR updates InputDecoration.helperMaxLines and InputDecoration.errorMaxLines comments.
Those comments have not been updated since they landed in https://github.com/flutter/flutter/pull/17292, at that time they were probably correct but unfortunately there were no tests to catch the change of behavior. This PR adds those two missing tests.
## Tests
Adds 2 tests.
Here's another PR with a couple of typos fixed. As you can see there was a typo in _fileReferenceI**n**dentifiers_, in class _ParsedProjectInfo._ Maybe we should do some check on that since I'm not sure if that property is used somewhere outside Flutter?
fixes [The image for the indicator of the TabBar does not auto-adapt to different resolutions](https://github.com/flutter/flutter/issues/145204)
### Description
This PR provides device pixel ratio to the tab indicator painter.
This pull request aims for improved readability, based on issue #146600.

fixes [DropdownMenu TrailingIcon can't be styled through providing an IconButtonTheme](https://github.com/flutter/flutter/issues/145081) (second PR)
### Description
This PR replaces `IconButton.style` with `ButtonStyle` when merging parent `IconButtonTheme` as `styleFrom` returns defaults for some properties.
## Description
This PRs fixes a null pointer exception thrown when reset is called on a `DropdownButtonFormField` whose `onChange` callback is null.

## Tests

This PR makes it possible to remove the hard-coded 32.0 unit padding coming from ListTile when trailing is not null. Which it always it as `ExpansionTile` always provides a widget there. Currently there is no way to remove it and people have to hack around it: e.g.
https://stackoverflow.com/questions/54714836/how-to-remove-default-padding-from-expansiontiles-header
The issue is quite old and I came across it today and decided to put together a quick fix.
Fixes#145268
The change should be non-breaking as the default stays the same. But I have no issue with changing something if requested. (naming-wise, functionality-wise etc...)
This PR adds a `semanticsLabel` field to the MenuItemButton, letting users pass in a Semantics Label if they have issues with the way a ScreenReader reads the generated text.
fixes: [142939: Screen Readers won't read punctuation characters in Shortcuts](https://github.com/flutter/flutter/issues/142939)
- Introduces the ability to control whether RawMagnifier uses a clip on
its decoration. (It still has to use a clip for its magnified image.)
- Uses `BlurStyle.outer` to remove the clip for CupertinoMagnifier.
- Many changes to the documentation around magnifiers and shadows.
- Implements `BoxShadow.copyWith` which somehow we had never needed
before.
- Makes `debugDisableShadows` handle `BlurStyle.outer` correctly.
- Adds `MagnifierInfo.toString`.
- Aligns various `operator ==`s with the style guide.
- Makes MagnifierDecoration a separate concept from Decoration, since
it's not actually compatible anywhere.
- Removes some dead code and makes other minor code simplifications.
- Uses double syntax rather than integer syntax for various double
literals for clarity.
I expect one minor golden image change (antialiasing change on
Cupertino's magnifier test).
fix#139486
The `expandedInsets` property enhancement for the `SegmentedButton` widget introduces flexibility in button layout design within Flutter applications. When `expandedInsets` is not null, this property allows the `SegmentedButton` to expand, filling the available horizontal space of its parent container and also have the specified insets, thus ensuring a uniform distribution of segment widths across the button. Conversely, with `expandedInsets` is null, the widget sizes itself based on the intrinsic sizes of its segments, preserving the natural width of each segment. This addition enhances the adaptability of the `SegmentedButton` to various UI designs, enabling developers to achieve both expansive and compact button layouts seamlessly.

It didn't include the label's Y offset. Also fixes the nullability of the slotted children: it seems `avatar`, `label`, `deleteIcon` can't be null when `_RenderChip` is in the render tree. We were using
```dart
_boxParentData(avatar!).offset = theme.padding.topLeft + avatarOffset;
_boxParentData(label!).offset = theme.padding.topLeft + labelOffset + theme.labelPadding.topLeft;
_boxParentData(deleteIcon!).offset = theme.padding.topLeft + deleteIconOffset;
```
in `performLayout` anyway.

fixes [DropdownMenuEntry Text Overflow when width of DropdownMenu is not specified](https://github.com/flutter/flutter/issues/140596)
### Description
- This PR continues the fix from https://github.com/flutter/flutter/pull/141314#issuecomment-1945804640 and adds controlled widths for the `MenuBar` children to fix the unbounded width issue which blocked the PR earlier. (Widgets with non-zero flex value cannot be laid out in a horizontal scroll view which is created by `MenuBar` widget)
- Added tests coverage.
- Added documentation.

### Before
### After
* Updated the Material Design tokens to v2.3.5
* Linear and circular progress indicator token sets are deprecated in v0.207. The `md.com.progress-indicator` token set was created and should be used instead.
* tokens is now using [semantic versioning](https://semver.org/) ï¼Thanks @guidezpl for reminding:) )
* ~Fixes #128877. The default text style is updated to `bodyLarge` now:)~ Added TODOs for the label text style of `PopupMenuButton`. Will create a separate PR because this change breaks Google testing.
