Fixes#141347
This PR is to add a "clear text" tooltip for the clear button on `SearchAnchor`'s search view and also add a `clearButtonTooltip` entry for `material_localizations`.
This is part 2 of a broken down version of the #140101 refactor.
This particular change wasn't in that original refactor but is a note to myself so that I remember how to test each of these changes in the future.
## Description
This removes an unneeded expectation in the test for the AppLifecycleListener. It's unneeded because the test immediately resets the state anyhow. I'm removing it because the web implementation sets the value when initializing, so it's never initially null there.

When a `TextField` is rendered before a `Navigator`, it breaks in semantics mode. This is because the framework generates the incorrect semantics tree (excludes the TextField) and when that tree gets sent to the engine, we don't get the signal to create the corresponding `<input>` element.
This happens for a few reasons:
* `ModalBarrier` uses `BlockSemantics` to drop the semantics of routes beneath the current route in `Navigator`
* `ModalBarrier` mistakenly recognizes the widget outside of the `Navigator` to be its sibling
* So we end up dropping the semantics node of the `TextField` rendered before it.
The fix is to let `Navigator` generate a semantics node so that `ModalBarrier` doesn't mistakenly think widgets outside of `Navigator` are its siblings.
`Navigator` doesn't currently do this, which causes all the nodes generated from its widget subtree to be directly attached to the parent semantics node above `Navigator` - since this is also the parent of `TextField`, it considers them siblings.

Remove more `textScaleFactor` references from flutter/flutter.
- Some changes are related to label scaling: the padding EdgeInsets values of some chip subclasses scale linearly between predetermined "max" padding values and "min" padding values. Before they scale with the `textScaleFactor` scalar, now they scale with the font size and are still capped at the original "max" and "min" values.
- The rest of them are tests or size heuristics that depend on `textScaleFactor`, these are replaced by an effective text scale factor computed using a default font size (which is determined in a pretty random fashion, but it will only make a difference on Android 14+).
No API changes in this batch. There are still some references left that I intend to remove in a different batch that would introduce API changes.
Much nicer calling API and simplifies evolving this API in the future.
I wish we could write a dart fix for this, but that's blocked on https://github.com/dart-lang/sdk/issues/54668.
- Unskip `text_style_test` for CanvasKit.
- Remove no longer necessary `kIsWeb` checks in a few tests.
This PR depends on https://github.com/flutter/engine/pull/49786, which rolled into the framework. If the engine PR needs to be reverted, this PR will need to be reverted too.
This PR improves the distance between the label and the icon in the Tab widget.
I updated the margin to 2 pixels, taken from the Figma design page for Material 3. On Material 2 I left the default value of 10 pixels.
Related to #128696 (In particular, the distance between label and icon)
Here are some screenshots for comparison. I looked a bit into the other mentioned issue of the tab height not following the M3 spec. Flutter uses 72 and the spec uses 64. But because Tab is a PreferredSizeWidget, I don't think there is an easy way to provide a different size depending on `ThemeData.useMaterial3`, because there is no `BuildContext` available.
I provide a sample image for the 64 height as well for context on the linked issue, even though it's not part of the PR changes.
The screenshots are taken side by side with the image at: https://m3.material.io/components/tabs/guidelines
## Original
## New (tab height = 72, Flutter default for 8 years)
## New (tab height = 64, M3 spec)
Previously `TextField`s error `cursorColor` was being derived without taking into account any `InputDecorationTheme` defaults. This change respects `InputDecorationTheme` defaults when deriving the error `cursorColor`.
Fixes#140607
This disables the expectation for `TileMode` stringification because
https://github.com/flutter/engine/pull/49786 is about to fix it (as in,
the test would fail when the engine fix lands).
Fixes#140046
This PR is to add a `headerHeight` property to `SearchAnchor` and `SearchViewThemeData` so the header height on the search view can be customized.
I continued [my mission](https://github.com/flutter/flutter/pull/141431) to find as many typos as I could. This time it's a smaller set than before.
There is no need for issues since it's a typo fix.
## Description
This PR addresses issue #141061, which requested the addition of a 'color' property to buttons extending _ActionButton. The 'color' property has been introduced to enhance customization options for these buttons.

### Before
### After
While working in https://pub.dev/packages/two_dimensional_scrollables, I found I could eliminate some casts if we added covariants here in the framework.
Much of the 2D aPI in the framework is abstract, so I think it make sense to add these and make it easier/cleaner for subclasses using the APIs.
I made a similar change in https://github.com/flutter/flutter/pull/131358, this would cover all of the cases I could find so its nice and accommodating now.
This PR fixes scrolling issues with `NestedScrollView` using the `BouncingScrollPhysics`. In one of the steps of the calculation, we can reach a state where the position of the inner scrollable is set to a `double` value that falls within `precisionErrorTolerance` of `0` but we were using `==` with `0` rather than checking for a precision. My posts in the linked issue show the current behavior, and how I reached to conclusion (the code in this PR). This PR only addresses the "jumping" of the outer scrollable.
Fixes#136199
I have not finished a test for this since I have never done so and therefore have 0 experience writing tests in Flutter, so any help there would be appreciated. I am also not sure how to test double precision errors in general. I did run all the nested_scroll_view_tests.dart locally and there are no failures.
Fixes#141140.
This ensures that if you call `.copyWith` and pass a `debugLabel`, the `debugLabel` won't be ignored, even if the receiver (the TextStyle you're calling `.copyWith` on) doesn't have a `debugLabel`.
The debugLabel field was added in #12552. I skimmed the discussion there and didn't find anything indicating that the param was being ignored on purpose.
I added a test case that passes with the new code and fails with the old code.
