Original Description:
`FocusNode.canRequestFocus` was doing a double traversal if no ancestor disallows focus. The last for loop only has to reach as far as the enclosing scope.
Also this caches the `FocusNode.enclosingScope` since the getter access happens much more frequently than node reparenting.

Reverts flutter/flutter#143973
This is a reland for #138521 with an updated g3fix(cl/605555997). Local test: cl/609608958.
`FocusNode.canRequestFocus` was doing a double traversal if no ancestor disallows focus. The last for loop only has to reach as far as the enclosing scope.
Also this caches the `FocusNode.enclosingScope` since the getter access happens much more frequently than node reparenting.
The original PR was reverted because the new caret positioning callpath triggered a skparagraph assert. The assert has been removed. Relanding the PR with no changes applied.
This pull request fixes#143803 by taking advantage of Dart's null-aware operators.
And unlike `switch` expressions ([9 PRs](https://github.com/flutter/flutter/pull/143634) and counting), the Flutter codebase is already fantastic when it comes to null-aware coding. After refactoring the entire repo, all the changes involving `?.` and `??` can fit into a single pull request.
Adds a localized Close Button tooltip to the 'X' Button on a SnackBar, making it readable by screen readers.
Github Issue #143793
*If you had to change anything in the [flutter/tests] repo, include a link to the migration guide as per the [breaking change policy].*
Fixes an issue where if the `TextSpan` doesn't have a text style, the specified strutStyle is not applied.
Additionally, adds a migration flag for https://github.com/flutter/engine/pull/50385, for internal golden changes. It's only going to exist for a week.
My RenderSliverMultiBoxAdaptor/RenderSliverFixedExtentList/RenderSliverVariedExtentList yak shave continues.
I've been subclassing RenderSliverVariedExtentList for SliverTree and have found some opportunities for clean up.
There is a larger clean up I'd like to do, but this week SliverTree comes first.
I noticed these methods were getting repeated ð, and I was about to repeat them again ð for the tree, so I figured bumping them up to the base class was better than continuing to copy-paste the same methods.
Multiple methods in `RenderSliverFixedExtentBoxAdaptor` pass a `double itemExtent` for computing things like what children will be laid out, what the max scroll offset will be, and how the children will be laid out.
Since `RenderSliverFixedExtentBoxAdaptor` was further subclassed to support a `itemExtentBuider` in `RenderSliverVariedExtentList`, these itemExtent parameters became useless when using that RenderObject. Reading through `RenderSliverFixedExtentBoxAdaptor.performLayout`, the remaining artifacts of passing around itemExtent make it hard to follow when it is irrelevant.
`RenderSliverFixedExtentBoxAdaptor.itemExtent` is available from these methods, so it does not need to pass it. It is redundant API.
Plus, if a bogus itemExtent is passed for some reason, errors will ensue and the layout will be incorrect. ð£ ð¥
Deprecating so we can remove these for a cleaner API. Unfortunately this is not supported by dart fix, but the fact that these methods are protected means usage outside of the framework is likely minimal.
fixes [`hourMinuteTextStyle` Material 3 default doesn't match the specs](https://github.com/flutter/flutter/issues/143748)
This updates `hourMinuteTextStyle` defaults to match Material 3 specs. `hourMinuteTextStyle` should use different font style for different entry modes based on the specs.
### Specs
### Before
```dart
return _textTheme.displayMedium!.copyWith(color: _hourMinuteTextColor.resolve(states));
```
### After
```dart
return entryMode == TimePickerEntryMode.dial
? _textTheme.displayLarge!.copyWith(color: _hourMinuteTextColor.resolve(states))
: _textTheme.displayMedium!.copyWith(color: _hourMinuteTextColor.resolve(states));
```
This PR fixes#142885.
The issue is that in `_RepeatingSimulation` the initial time is calculated as follows:
```
(initialValue / (max - min)) * (period.inMicroseconds / Duration.microsecondsPerSecond)
```
This calculation does not work in general. For instance, if `max` is 300, `min` is 100, and `initialValue` is 100 then `initialValue / (max - min)` is 1/2 when it should be 0
The current tests work by happenstance because the numbers used happen to work. To reveal the bug I've added some more tests similar to the existing ones but with different numbers.
A "side-effect" of the incorrect calculation is that if `initialValue` is 0, then the animation will always start from `min` no matter what. For instance, in one of the tests, an `AnimationController` with the value 0 is told to `repeat` between 0.5 and 1.0, and this starts the animation from 0.5. To preserve this behavior, and to more generally handle the case where the initial value is out of bounds, this PR clamps the initial value to be within the lower and upper bounds of the repetition.
Just for reference, this calculation was introduced at https://github.com/flutter/flutter/pull/25125.

Original Description:
The behavior largely remains the same, except:
1. The EOT cursor `(textLength, downstream)` for text ending in the opposite writing direction as the paragraph is now placed at the visual end of the last line.
For example, in a LTR paragraph, the EOT cursor for `aA` (lowercase for LTR and uppercase for RTL) is placed to the right of the line: `aA|` (it was `a|A` before).
This matches the behavior of most applications that do logical order arrow key navigation instead of visual order navigation.
And it makes the navigation order consistent for `aA\naA`:
```
|aA => aA| => aA| => aA => aA => aA
aA aA aA |aA aA| aA|
(1) (2) (3) (4) (5) (6)
```
This is indeed still pretty confusing as (2) and (3), as well as (5) and (6) are hard to distinguish (when the I beam has a large width they are actually visually distinguishable -- they use the same anchor but one gets painted to the left and the other to the right. I noticed that emacs does the same).
But logical order navigation will always be confusing in bidi text, in one way or another.
Interestingly there are 3 different behaviors I've observed in chrome:
- the chrome download dialog (which I think uses GTK text widgets but not sure which version) gives me 2 cursors when navigating bidi text, and
- its HTML fields only show one, and presumably they place the I beam at the **trailing edge** of the character (which makes more sense for backspacing I guess).
- On the other hand, its (new) omnibar seems to use visual order arrow navigation
Side note: we may need to update the "tap to place the caret here" logic to handle the case where the tap lands outside of the text and the text ends in the opposite writing direction.
2. Removed the logarithmic search. The same could be done using the characters package but when glyphInfo tells you about the baseline location in the future we probably don't need the `getBoxesForRange` call. This should fix https://github.com/flutter/flutter/issues/123424.
## Internal Tests
This is going to change the image output of some internal golden tests. I'm planning to merge https://github.com/flutter/flutter/pull/143281 before this to avoid updating the same golden files twice for invalid selections.

## Description
This PR is the third step for the M3 test migration for `InputDecorator`.
Step 1: https://github.com/flutter/flutter/pull/142981
Step 2: https://github.com/flutter/flutter/pull/143369
This PR moves some tests out of the 'Material2' group (the ones that are ok on M3).
@justinmc The diff is almost unreadable, I moved the tests as carefully as possible and I checked that before and after the number of tests is exactly the same.
## Related Issue
Related to https://github.com/flutter/flutter/issues/139076
## Tests
Move some tests from 'Material2' group to main().
Fixes https://github.com/flutter/flutter/issues/79495
This is basically a reland of https://github.com/flutter/flutter/pull/79607.
Currently when the cursor is invalid, arrow key navigation / typing / backspacing doesn't work since the cursor position is unknown.
Showing the cursor when the selection is invalid gives the user the wrong information about the current insert point in the text.
This is going to break internal golden tests.

Add a semantics flag to text field to fix https://github.com/flutter/flutter/issues/143337 (in IOS the disabled text field is not read `dimmed`)
internal: b/322345393
## Description
This PR is the second step for the M3 test migration for `InputDecorator` (step 1 was https://github.com/flutter/flutter/pull/142981).
This PR migrate the two first tests of the M2 section. Those were big tests. I splitted them in several testsn organized in groups, and I narrowed their scope when possible.
@justinmc I did not move yet the M2 tests to a separate file (I move them to a group) because it would mean we loss the line history which is useful during the migration. In the next step, I will focus on moving out some tests that are in the 'Material2' group (the ones that are ok with both M2 and M3).
