chunhtai d0058ec361 Adds radio group widget r2 (#168161 ) <!-- Thanks for filing a pull request! Reviewers are typically assigned within a week of filing a request. To learn more about code review, see our documentation on Tree Hygiene: https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md --> previous https://github.com/flutter/flutter/pull/167363 I have to factor out abstract class for RadioGroupRegistry and RadioClient which are subclassed by RadioGroupState and RawRadio respectively. I have to do this because the RadioListTile that has 2 focusnode one for listTile and one for the radio it builds. The issue is that RadioGroup's keyboard shortcut has to tightly couples with the focus node of each radio, but the radioListtile has to mute the radio's focusnode so it can act as one control under keyboard shortcut `d582b35809/packages/flutter/lib/src/material/radio_list_tile.dart (L484)` Therefore i abstract the out the logic of RadioGroup so that another widget can participate by implementing the interface. fixes https://github.com/flutter/flutter/issues/113562 migration guide: https://github.com/flutter/website/pull/12080/files ## Pre-launch Checklist - [ ] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [ ] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [ ] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [ ] I signed the [CLA]. - [ ] I listed at least one issue that this PR fixes in the description above. - [ ] I updated/added relevant documentation (doc comments with `///`). - [ ] I added new tests to check the change I am making, or this PR is [test-exempt]. - [ ] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [ ] All existing and new tests are passing.

Flutter Examples

This directory contains several examples of using Flutter. To run an example, use flutter run inside that example's directory. See the getting started guide to install the flutter tool.

For additional samples, see the flutter/samples repo.

Available examples include:

Hello, world The hello world app is a minimal Flutter app that shows the text "Hello, world!"
Flutter gallery The flutter gallery app no longer lives in this repo. Please see the gallery repo.
Layers The layers vignettes show how to use the various layers in the Flutter framework. For details, see the layers README.
Platform Channel The platform channel app demonstrates how to connect a Flutter app to platform-specific APIs. For documentation, see https://flutter.dev/to/platform-channels/.
Platform Channel Swift The platform channel swift app is the same as platform channel but the iOS version is in Swift and there is no Android version.

Notes

Note on Gradle wrapper files in .gitignore:

Gradle wrapper files should normally be checked into source control. The example projects don't do that to avoid having several copies of the wrapper binary in the Flutter repo. Instead, the Gradle wrapper is injected by Flutter tooling, and the wrapper files are .gitignore'd to avoid making the Flutter repository dirty as a side effect of running the examples.
