Root predictive back (https://github.com/flutter/flutter/pull/120385) was reverted in https://github.com/flutter/flutter/pull/132167. This PR is an attempt to reland it. The reversion happened due to failed Google tests (b/295073110).

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.

Updates examples to use the new `ListenableBuilder` if there's no animation. This is slightly more idiomatic.

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. ![Application Lifecycle Diagram](https://github.com/flutter/flutter/assets/8867023/f6937002-cb93-4ab9-a221-25de2c45cf0e) ## Related Issues - https://github.com/flutter/flutter/issues/30735 ## Tests - Added tests for new lifecycle value, as well as for the `AppLifecycleListener` itself.

This widget implements the ability to place slivers one after another in a single ScrollView in a way that all child slivers are drawn within the bounds of the group itself (i.e. SliverPersistentHeaders aren't drawn outside of the scroll extent provided by all of the child slivers).

This is a proof of concept for renaming SlottedMultiChildRenderObjectWidgetMixin to SlottedMultiChildRenderObjectWidget and making it a concrete class. I also made SlottedContainerRenderObjectMixin generic instead of being specialized to RenderBox. I don't think this is something we can easily automigrate, but we may not need to, I don't know how common this is...

Add ScrollController.onAttach & onDetach, samples/docs on listening/getting scrolling info (#124823) This PR does a couple of things! https://user-images.githubusercontent.com/16964204/231897483-416287f9-50ce-468d-a714-2a4bc0f2e011.mov ![Screenshot 2023-04-13 at 3 24 28 PM](https://user-images.githubusercontent.com/16964204/231897497-f5bee17d-43ed-46e5-acd7-e1bd64768274.png) Fixes #20819 Fixes #41910 Fixes #121419 ### Adds ScrollController.onAttach and ScrollController.onDetach This resolves a long held pain point for developers. When using a scroll controller, there is not scroll position until the scrollable widget is built, and almost all methods of notification are only triggered when scrolling happens. Adding these two methods will help developers gain access to the scroll position when it is created. A common workaround for this was using a post frame callback to access controller.position after the first frame, but this is ripe for issues such as having multiple positions attached to the controller, or the scrollable no longer existing after that post frame callback. I think this can also be helpful for folks to debug cases when the scroll controller has multiple positions attached. In particular, this also resolves this commented case: https://github.com/flutter/flutter/issues/20819#issuecomment-417784218 The isScrollingNotifier is hard for developers to access. ### Docs & samples I was surprised we did not have samples on scroll notification or scroll controller, so I overhauled it and added a lot of docs on all the different ways to access scrolling information, when it is available and how they differ.

fixes https://github.com/flutter/flutter/issues/115898 `hasChild` checks `_idToChild` map. `_idToChild` is not assigned until `_callPerformLayout` is called. So `hasChild` shouldn't be called in `getSize`. https://github.com/flutter/flutter/blob/df789c9e76098e82f80f2c5de8b5560f360afa40/packages/flutter/lib/src/rendering/custom_layout.dart#L400-L404 Updated docs and example class names.
