"showSnackBar()" is now a feature of a Scaffold. To get to a Scaffold you either use a global key (`scaffoldKey.currentState.showSnackBar(...)`), or you use `Scaffold.of(context)`. Snack bars no longer have a route. They are entirely managed by the Scaffold. Fixes #432. Snack bars now queue up when you have several of them. Fixes #374. Snack bars now auto-size themselves around their contents. This is step one towards implementing multiline snack bars. Snack bars now self-dismiss after some per-snackbar configurable period. The self-dismissing pauses while a dialog is up above the snackbar (or anything that uses ModalRoute). To enable this, there's now a `ModalRoute.of(context)` API that returns the current ModalRoute, and you will be rebuilt if you asked for this and the route's "current" status changes. To implement this, the Navigator now rebuilds unconditionally any time it pushes or pops a route. Snack bars now use the curves that Android uses for snack bars. Snack bar contents now fade in.
Flutter Examples
This directory contains several examples of using Flutter. Each of these is an individual Dart application package.
To run a sample with the flutter tool, run pub get inside its directory,
then run flutter start. (See the
getting started guide to install
the flutter tool.)
Available examples include:
-
Hello, world. The hello world app is a basic app that shows the text "hello, world."
-
Stocks. The stocks app is an example of a typical mobile app built using Flutter. The app shows a list of all the stocks in the NASDAQ.
-
Widgets. The widget apps demonstrate a number of Flutter widgets so you can experiment with them in a simple container. There is no main.dart in this directory because each file is a standalone sample. To run a particular file, use
flutter start -t filename.dart.
