Enabled displaying a scrollbar in ScrollingLists. The scrollbar is painted as an "overlay", i.e. it's painted on top of the scrolling list's visible children. Added an abstract Painter base class that encapsulates a paint method and the renderer that it's attached to. RenderBlockViewport and HomogenousViewport now support an overlayPainter property. If specified, RenderBlockViewport attaches itself to the overlayPainter when it's attached to the rendering tree. RenderBlockViewport now calls overlayPainter.paint() after it has painted its children. Added an abstract ScrollingListPainter class that exposes ScrollingList's state which might be needed for painting. Like its scroll direction and scrollOffset. The ScrollingListPainter is notified when a scroll starts and ends. Defined a Material-specific ScrollingListPainter that renders a scrollbar. The scrollbar thumb is faded in/out when the scroll starts/ends. Added onScrollStart and onScrollEnd listeners to Scrollable.
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.
