Move the notch computation from the FAB to the BAB. The notch in the BAB (bottom action bar) for the FAB (floating action button) was previously kept as part of the FAB's implementation. This was done to keep the shape of the FAB and the shape of the notch coupled. That approach resulted in a somewhat complex and 'non Fluttery' mechanism for propagating the notch computation from the FAB to the BAB. This CL uncouples the FAB and the notch computation. With the new API the BAB computes its overall shape including the notch using a NotchedShape delegate. This includes multiple breaking changes: * Scaffold.setFloatingActionButtonNotchFor is deleted. * The ComputeNotch type is deleted. * The hasNotch property of BottomAppBar is deleted. * The notchMargin property of FloatingActionButton is deleted. Quick migration guide from the previous API: | Previous API | New API | | ------------------|-------------| | BottomAppBar(hasNotch: false) | BottomAppBar() | | Using a FloatingActionButton with: BottomAppBar() / BottomAppBar(hasNotch: true) | BottomAppBar(shape: CircularNotchedRectangle()) | | Scaffold.setFloatingActionButtonNotchFor(..) | No longer supported | |

Flutter Examples
This directory contains several examples of using Flutter. Each of these is an individual Dart application package.
To run an example, use flutter run inside that example's directory. See the
getting started guide to install
the flutter tool.
Tip: To see examples of how to use a specific Flutter framework class,
copy and paste a URL with this format in your browser. Replace foo with the
classname you are searching for (for example, here's the
query
for examples of the
AppBar class).

Available examples include:
-
Hello, world The hello world app is a basic app that shows the text "hello, world."
-
Flutter gallery The flutter gallery app showcases Flutter's widgets, including its implementation of material design.
-
Platform Channel The platform channel app demonstrates how to connect a Flutter app to platform-specific APIs. For documentation, see https://flutter.io/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.
-
Flutter View The flutter view app demonstrates how to embed Flutter within an iOS or Android app.
-
Layers The layers vignettes show how to use the various layers in the Flutter framework. For details, see the layers README.
-
Stocks The stocks demo shows how one might structure an application with several screens.
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.
