Many of the widgets that use CustomPaint were spamming repaints because CustomPaint repaints when the identity of the onPaint callback changes, which it does every build for StatelessComponents. This patch changes CustomPaint to use a CustomPainter, similar to the new custom layout widgets. The CustomPainter has a `shouldRepaint` function along with its `paint` function. This function gives clients explicit control over when the custom paint object repaints.
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.
