Reverts flutter/flutter#125927 context: b/300804374 Looks like a g3 fix might involve changing the names of widget on the customer app, and I am not sure if that would be the right approach forward. Putting up a revert to be safe for now.

### Description This PR is to improve `DropdownMenu` sample code. By default, `requestFocusOnTap` is false on mobile platforms. When users run API sample code on mobile platforms, they can not edit the text field and think it is a bug. Although it is detailed at https://api.flutter.dev/flutter/material/DropdownMenu/requestFocusOnTap.html, users often do not pay attention to it. ### Related issue Fixes https://github.com/flutter/flutter/issues/127672

New example for `InputChip` that demonstrate how to create/delete them based on user text inputs. The sample application shows a custom text area where user can enter text. After the user has typed and hits _Enter_ the text will be replaced with an `InputChip` that contains that text. Is it possible to continue typing and add more chips in this way. All of them will be placed in a scrollable horizontal row. Also is it possible to have suggestion displayed below the text input field in case the typed text match some of the available suggestions. Issue I'm trying to solve: - https://github.com/flutter/flutter/issues/128247 **Code structure:** The example app is composed of 2 main components that find places inside `MainScreen`: - `ChipsInput` - `ListView` `ChipsInput` emulates a `TextField` where you can enter text. This text field accepts also a list of values of generic type T (`Topping` in my example), that gets rendered as `InputChip` inside the text field, before the text inserted by the user. This widgets is basically an `InputDecorator` widget that implements `TextInputClient` to get `TextEditingValue` events from the user keyboard. At the end of the input field there is another component, the `TextCursor`, that is displayed just when the user give the focus to the field and emulates the carrets that `TextField` has. There are also some available callbacks that the user can use to capture events in the `ChipsInput` field like: `onChanged`, `onChipTapped`, `onSubmitted` and `onTextChanged`. This last callback is used to build a list of suggestion that will be placed just below the `ChipsInput` field inside the `ListView`.

- slightly improved assert message when row cell counts don't match column count. - more breadcrumbs in API documentation. more documentation in general. - added more documentation for the direction of the "ascending" arrow. - two samples for PaginatedDataTable. - make PaginatedDataTable support hot reloading across changes to the number of columns. - introduce matrix3MoreOrLessEquals. An earlier version of this PR used it in tests, but eventually it was not needed. The function seems useful to keep though.

This PR aims to support Android's predictive back gesture when popping the entire Flutter app. Predictive route transitions between routes inside of a Flutter app will come later. <img width="200" src="https://user-images.githubusercontent.com/389558/217918109-945febaa-9086-41cc-a476-1a189c7831d8.gif" /> ### Trying it out If you want to try this feature yourself, here are the necessary steps: 1. Run Android 33 or above. 1. Enable the feature flag for predictive back on the device under "Developer options". 1. Create a Flutter project, or clone [my example project](https://github.com/justinmc/flutter_predictive_back_examples). 1. Set `android:enableOnBackInvokedCallback="true"` in android/app/src/main/AndroidManifest.xml (already done in the example project). 1. Check out this branch. 1. Run the app. Perform a back gesture (swipe from the left side of the screen). You should see the predictive back animation like in the animation above and be able to commit or cancel it. ### go_router support go_router works with predictive back out of the box because it uses a Navigator internally that dispatches NavigationNotifications! ~~go_router can be supported by adding a listener to the router and updating SystemNavigator.setFrameworkHandlesBack.~~ Similar to with nested Navigators, nested go_routers is supported by using a PopScope widget. <details> <summary>Full example of nested go_routers</summary> ```dart // Copyright 2014 The Flutter Authors.

Deprecate `textScaleFactor` in favor of `textScaler`, in preparation for Android 14 [Non-linear font scaling to 200%](https://developer.android.com/about/versions/14/features#non-linear-font-scaling). The `TextScaler` class can be moved to `dart:ui` in the future, if we decide to use the Android platform API or AndroidX to get the scaling curve instead of hard coding the curve in the framework. I haven't put the Flutter version in the deprecation message so the analyzer checks are failing. Will do so after I finish the migration guide. **Why `TextScaler.textScaleFactor`** The author of a `TextScaler` subclass should provide a fallback `textScaleFactor`. By making `TextScaler` also contain the `textScaleFactor` information it also makes it easier to migrate: if a widget overrides `MediaQueryData.textScaler` in the tree, for unmigrated widgets in the subtree it would also have to override `MediaQueryData.textScaleFactor`, and that makes it difficult to remove `MediaQueryData.textScaleFactor` in the future. ## A full list of affected APIs in this PR Deprecated: The method/getter/setter/argument is annotated with a `@Deprecated()` annotation in this PR, and the caller should replace it with `textScaler` instead. Unless otherwise specified there will be a Flutter fix available to help with migration but it's still recommended to migrate case-by-case. **Replaced**: The method this `textScaleFactor` argument belongs to is rarely called directly by user code and is not overridden by any of the registered custom tests, so the argument is directly replaced by `TextScaler`. **To Be Deprecated**: The method/getter/setter/argument can't be deprecated in this PR because a registered customer test depends on it and a Flutter fix isn't available (or the test was run without applying flutter fixes first). This method/getter/setter/argument will be deprecated in a followup PR once the registered test is migrated. ### `Painting` Library | Affected API | State of `textScaleFactor` | Comment | | --- | --- | --- | | `InlineSpan.build({ double textScaleFactor = 1.0 })` argument | **Replaced** | | | `TextStyle.getParagraphStyle({ double TextScaleFactor = 1.0 })` argument | **Replaced** | | | `TextStyle.getTextStyle({ double TextScaleFactor = 1.0 })` argument| Deprecated | Can't replace: https://github.com/superlistapp/super_editor/blob/c47fd38dca4b7f43611690913b551a1773c563d7/super_editor/lib/src/infrastructure/super_textfield/desktop/desktop_textfield.dart#L1903-L1905| | `TextPainter({ double TextScaleFactor = 1.0 })` constructor argument | Deprecated | | | `TextPainter.textScaleFactor` getter and setter | Deprecated | No Flutter Fix, not expressible yet | | `TextPainter.computeWidth({ double TextScaleFactor = 1.0 })` argument | Deprecated | | | `TextPainter.computeMaxIntrinsicWidth({ double TextScaleFactor = 1.0 })` argument | Deprecated | | ### `Rendering` Library | Affected API | State of `textScaleFactor` | Comment | | --- | --- | --- | | `RenderEditable({ double TextScaleFactor = 1.0 })` constructor argument | Deprecated | | | `RenderEditable.textScaleFactor` getter and setter | Deprecated | No Flutter Fix, not expressible yet | | `RenderParagraph({ double TextScaleFactor = 1.0 })` constructor argument | Deprecated | | | `RenderParagraph.textScaleFactor` getter and setter | Deprecated | No Flutter Fix, not expressible yet | ### `Widgets` Library | Affected API | State of `textScaleFactor` | Comment | | --- | --- | --- | | `MediaQueryData({ double TextScaleFactor = 1.0 })` constructor argument | **To Be Deprecated** | https://github.com/flutter/packages/blob/cd7b93532e5cb605a42735e20f1de70fc00adae7/packages/flutter_markdown/test/text_scale_factor_test.dart#LL39C21-L39C35 | | `MediaQueryData.textScaleFactor` getter | Deprecated | | | `MediaQueryData.copyWith({ double?

This change updates `SelectableRegion`s right-click gesture to match native platform behavior. Before: Right-click gesture selects word at position and opens context menu (All Platforms) After: - Linux, toggles context menu on/off, and collapses selection when click was not on an active selection (uncollapsed). - Windows, Android, Fuchsia, shows context menu at right-clicked position (unless the click is at an active selection). - macOS, toggles the context menu if right click was at the same position as the previous / or selects word at position and opens context menu. - iOS, selects word at position and opens context menu. This change also prevents the `copy` menu button from being shown when there is a collapsed selection (nothing to copy). Fixes #117561

This is a second attempt to merge #107269. Currently I've fixed two of the issues: 1. Fixed horizontal scrollview by using a switch statement to consider vertical/horizontal case. 2. Fixed issue of `paintExtent` not being the right extent for painting. Rather using a `scrollExtent` for the main axis length of the decoration box and painting it offsetted by the `scrollOffset`. 3. If the sliver child has inifinite scrollExtent, then we only draw the decoration down to the bottom of the `cacheExtent`. The developer is expected to ensure that the border does not creep up above the cache area. This PR includes a test that checks that the correct rectangle is drawn at a certain scrollOffset for both the horizontal and vertical case which should be sufficient for checking that `SliverDecoration` works properly now. Fixes https://github.com/flutter/flutter/issues/107498.

## Description This adds `AppLifecycleListener`, a class for listening to changes in the application lifecycle, and responding to requests to exit the application. It depends on changes in the Engine that add new lifecycle states: https://github.com/flutter/engine/pull/42418 Here's a diagram for the lifecycle states. I'll add a similar diagram to the documentation for these classes.  ## Related Issues - https://github.com/flutter/flutter/issues/30735 ## Tests - Added tests for new lifecycle value, as well as for the `AppLifecycleListener` itself.
