Before this change, long-running post-frame callbacks wouldn't show up in the timeline at all. This adds a timeline event for post-frame callbacks, with a debug flag that will add timeline events for each individual callback.
#testexempt -- we have no way to test calls to the timeline.
Fixes#136735
This PR is to add a searchCallback to allow users to customize the search algorithm. This feature is used to fix b/305662376 which needs an exact match algorithm.

Consider a scenario where the background color and indicator's background color are the same.
Adding a stroke color to the value indicator would be a valuable for the following reasons:
- **Visual Clarity:** It would allow developers to make the value indicator stand out more against the background, making it easier for users to notice.
- **Customization:** It would provide more flexibility in customizing the appearance of the sliding widget, allowing developers to match the design requirements of their apps.
- **Accessibility:** Improved visual distinction can enhance the accessibility of the sliding widget for users with various needs.

Fixes#135984
The documentation for using `findChildIndexCallback` recommends using `indexOf`, but that causes [this line](05259ca938/packages/flutter/lib/src/rendering/sliver_multi_box_adaptor.dart (L259)) to throw in debug mode, and when using `SliverList`, it breaks the render.
This PR changes the usage to check if the index is not negative before using it, and changes to return `null` instead if the child wasn't able to be found.
There's the related issue #107123, but this doesn't actually fix it.
-----
This PR has been updated to add the snippets that were used in the `findChildIndexCallback` comment as examples with proper tests, as well as updating the comment to reference the new examples.

Before this change, the render object was storing the `context.canvas` and using it after painting children. If those children were composited (e.g. because of an `Opacity` layer), the canvas it stored was disposed and not valid for use anymore.
### Description
- Fixes https://github.com/flutter/flutter/issues/134205.
### Tests
- Removes ignoring the `_RestorableRouteInformation` leak from `cupertino/app_test.dart`;
- Removes ignoring the `_RestorableRouteInformation` leak from `material/app_test.dart`;
- Removes ignoring the `_RestorableRouteInformation` leak from `widgets/app_test.dart`;
- Removes ignoring the `_RestorableRouteInformation` leak from `widgets/route_notification_messages_test.dart`;
- Removes ignoring the `_RestorableRouteInformation` leak from `widgets/router_restoration_test.dart`;
- Updates `widgets/router_test.dart` to use `testWidgetsWithLeakTracking`.
Some render box subclasses have a specific layout contract that is tightly coupled with other render box subclasses (e.g. two private classes in a local project file). In these cases, it is also possible that they use a constraints object that is a subclass of `BoxConstraints`. To allow for this, this change makes the `constraints` argument to `RenderBox.computeDryLayout()` a covariant argument.
For completeness' sake, this updates the other render objects in the rendering package to also use the covariant keyword for this argument.
## Description
In order for `MenuAnchor` menus to be able to not pass on the taps that close their menus, `TapRegion` needed a way to consume them. This change adds a flag to the `TapRegion`, `consumeOutsideTap` that will consume taps that occur outside of the region if the flag is set (it is false by default). The same flag is added to `MenuAnchor` to allow selecting the behavior for menus.
`TapRegion` consumes the tap event by registering with the gesture arena and immediately resolving the tap as accepted if any regions in a group have `consumeOutsideTap` set to true.
This PR also deprecates `MenuAnchor.anchorTapClosesMenu`, since it is a much more limited version of the same feature that only applied to the anchor itself, and even then only applied to closing the menu, not passing along the tap. The same functionality can now be implemented by handling a tap on the anchor widget and checking to see if the menu is open before closing it.
## Related Issues
- https://github.com/flutter/flutter/issues/135327
## Tests
- Added tests for `TapRegion` to make sure taps are consumed properly.
This PR is adding a listener to the `SearchController`, so that the `suggestionBuilder` can be updated when the `SearchController` changes.
Another method we can possibly do is have an update method on `SearchController`, so that the user can manually update the suggestions instead of us doing it automatically.
Fixes#132161
This fixes/notates a few deprecations from an audit for the next tech debt cycle.
- ThemeData errorColor and backgroundColor are notated as deprecated in multiple places, but one usage had a different version tag. Updated to match the rest.
- ThemeData.copyWith useMaterial3 was deprecated because it did not do what developers expected - it did not automatically reassign all of the color values and such. (confirmed with @HansMuller) I added a note so that when we later remove it we don't introduce a bug.
- the describeEnum deprecation was tagged wrong, it was a very long PR so by the time it merged the version it was finally tagged with was much later. (https://github.com/flutter/flutter/pull/125016)
fixes [`flexible_space_bar.dart': Failed assertion: line 475 pos 12: 'needsCompositing': is not true.` is thrown when scrolling down in the list and then up](https://github.com/flutter/flutter/issues/135698)
## Description
This adds a mechanism for listening to key events before or after focus traversal occurs.
It adds four methods to the public `FocusManager` API:
- `addEarlyKeyEventHandler` - Adds a handler that can handle events before they are given to the focus tree for handling.
- `removeEarlyKeyEventHandler` - Removes an early event handler.
- `addLateKeyEventHandler` - Adds a handler that can handle events if they have not been handled by anything in the focus tree.
- `removeLateKeyEventHandler` - Removes a late event handler.
This allows an app to get notified for a key anywhere, and prevent the focus tree from seeing that event if it handles it.
For the menu system, this allows it to eat an escape key press and close all the open menus.

- Added tests for new functionality.
In the past I switched the implementation of the zoom page transition because the performance of the old transition was terrible, but I'm hopeful that with Impeller we'll be able to identify and fix the issues that made it so slow. In order to evaluate this though, we need to be able to opt into the old transition for benchmarks on CI.

We delegate page up / page down actions to the browser. However, we don't let the browser scroll the underlying `<textarea>` - the framework handles scrolling, so page up/down don't end up doing anything. Since the framework handles scrolling for text inputs and textareas, we should let it also handle the actions for `page up`, `page down`, `home`, `end`, and their modifiers.

## Description
This updates the documentation for `MediaQuery` and `Overlay` to include the following:
- That `MediaQueryData.size` is set asynchronously, and doesn't necessarily reflect the size of the current frame.
- That the specific `MediaQuery.sizeOf` and related methods are preferred over the more generic `MediaQuery.of`.
- That the size of the `Overlay` isn't necessarily the size returned by `MediaQueryData.size`
As well as adding some symbol links, and fixing some error in documentation.
## Tests
- Documentation only
This PR updates unit tests from bottom sheet tests for M3 migration.
More info in https://github.com/flutter/flutter/issues/127064
It also contains in bottom_sheet.dart where a default value took precedence over a theme attribute.
Fixes https://github.com/flutter/flutter/issues/134656
`_skipMarkNeesLayout` was meant to only skip `markNeedsLayout` calls. Re-painting is still needed when a child gets added/removed from the `Overlay`.
