This change reverts the following previous change:
This is a reland of #177570, which was reverted in #178744 due to test
failures.

The original PR introduced `hitTestBehavior` to the semantics framework
but incorrectly applied `opaque` behavior to `ModalRoute`, which blocked
platform views from receiving pointer events.

Instead of making the entire modal opaque, we:
1. Keep `ModalRoute` without explicit `hitTestBehavior` (defaults to
`defer`)
2. Make only the dialog/sheet content opaque (blocks clicks to barrier)
3. Platform views remain clickable because they're outside the opaque
content boundary

Make SettingsChannel configuration queue not static (#179636)

SettingsChannel has a static data structure that stores system
configurations. This is fine if there is one engine. If there are two
FlutterViews and two engines - this static configuration is shared
between the two different engines. Because of the way the queue deletes
old entries this will result in one engine missing it's configuration.

added onUserInteractionIfError for form (#175515)

This PR adds a new `AutovalidateMode` value:
`onUserInteractionIfError`.

This mode allows `Form` and `FormField` widgets to auto-validate **only
when a field already has an error and the user interacts with it
again**.

- Current modes (`disabled`, `always`, `onUserInteraction`, `onUnfocus`)
do not cover the case where developers want validation **only when
correcting an error**.
- This improves UX by reducing unnecessary validation calls while still
ensuring errors disappear as soon as the user fixes them.

- Added `onUserInteractionIfError` to `AutovalidateMode`.
- Updated Dartdoc with detailed description and example snippet.
- Added new unit tests to validate behavior.
- Verified no regressions in other modes (`always`, `onUnfocus`,
`onUserInteraction`).

```dart
TextFormField(
  autovalidateMode: AutovalidateMode.onUserInteractionIfError,
  validator: (value) => value!.isEmpty ? 'Required field' : null,
)
````

---

Fixes #\<INSERT\_RELATED\_ISSUE\_NUMBER\_IF\_ANY>

---

* Added widget tests to confirm that:

  * No validation occurs until a field has an error.
* Once an error exists, validation runs automatically on user
interaction.
  * Resetting the form clears errors correctly.
* Regression tests ensure that `always`, `onUserInteraction`, and
`onUnfocus` modes still behave correctly.

---

* [x] I have read the [[Contributor
Guide](https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md)](https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md)
* [x] I have read the \[Tree Hygiene] wiki page and followed its
guidance
* [x] I have read and followed the \[Flutter Style Guide]
* [x] I signed the \[CLA]
* [x] I added a new enum value with clear Dartdoc
(`onUserInteractionIfError`)
* [x] I added example code in the Dartdoc
* [x] I added new widget/unit tests for the new mode
* [x] All existing and new tests pass
* [x] I ran `flutter analyze` and fixed all issues
* [x] No breaking changes introduced (or marked accordingly)

---

* [x] Yes
* [x] No

---

*(N/A — logic-only change)*

---

* The new mode reduces unnecessary validation until the user corrects an
error.
* All tests confirm correct behavior and no regressions in existing
modes.

Reland: Add framework-side hitTestBehavior support to Semantics (#178817) (#179352)

This is a reland of #178817, which was reverted in #179100 due to test
failures.

The original PR introduced `hitTestBehavior` to the semantics framework
but incorrectly applied `opaque` behavior to `ModalRoute`, which blocked
platform views from receiving pointer events.

Instead of making the entire modal opaque, we:
1. Keep `ModalRoute` without explicit `hitTestBehavior` (defaults to
`defer`)
2. Make only the dialog/sheet content opaque (blocks clicks to barrier)
3. Platform views remain clickable because they're outside the opaque
content boundary

Fixes #149001
Original PR: #177570
Revert: #178744

[ Analysis ] Added initial implementation of the `flutter_analyzer_plugin` (#175679)

The `flutter_analyzer_plugin` implements rules previously enforced by
the `dev/bots/analyze.dart` check run on the CI, allowing for earlier
detection of custom lint violations before a change is uploaded for
review.

Currently, the plugin implements the following rules:

  - avoid_future_catch_error
  - no_double_clamp
  - no_stopwatches
  - protect_public_state_subtypes
  - render_box_intrinsics

[ Tool ] Assemble: "Improper" validation error when dealing with base64 encoded dart-define value  (#178737)

addressing a regression from #172510 that caused the assemble command to
fail in the validation phase when a dart-define was passed as a
base64-encoded value.

Example command:
```

  -dTargetFile=lib/main.dart \

[fuchsia] temporarily disable touch-input-test due to the flakiness (#179747)

The FlutterEmbedTapTest.* are running on fuchsia_debug_x64_tester, and
they are recently flaky; FlutterTapTest is less but still flaky.

Before finding out the root cause, disabling the test suite is better
than disabling the entire builder.

[ios][pv] accept/reject gesture based on hitTest (with new widget API) (#179659)

This is a follow up PR to [this original
PR](https://github.com/flutter/flutter/pull/177859).

The difference is the API - the original PR chooses Option 1 [in the
design
doc](https://docs.google.com/document/d/1ag4drAdJsR7y-rQZkqJWc6tOQ4qCbflQSGyoxsSC6MM/edit?tab=t.0),
while this PR chooses Option 3.

To directly use flutter API, just pass in the policy when creating
UiKitView widget.

```
UiKitView(
  ...
  gestureBlockingPolicy: UiKitViewGestureBlockingPolicy)
  ...
)
```

For plugins, we need to update plugins to use this new API.

```
WebView(
  ...
  gestureBlockingPolicy: UiKitViewGestureBlockingPolicy
) {
  return UiKitView(
    ..
    gestureBlockingPolicy: gestureBlockingPolicy
  )
}
```
For more information, refer to [the old
PR](https://github.com/flutter/flutter/pull/177859).

issue. An issue is not required if the PR fixes something trivial like a

Fix draggable scrollable sheet example drag speed is off  (#179179)

- Fix https://github.com/flutter/flutter/issues/179102
- In this PR:
- Fix the sheet position so that it will follow the pointer, even when
dragging mouse beyond the window then returns inside.
    - Some improvement for coding convention:
- declare minChildSize and maxChildSize const(s) then use them in the
hardcoded positions
- move `_isOnDesktopAndWeb` out of Grabber, so it's easier to see
Grabber widget purpose when reading the code

Comments from the `gemini-code-assist` bot should not be taken as
authoritative feedback from the Flutter team. If you find its comments
useful you can update your code accordingly, but if you are unsure or
