This patch simplifies PaintingContext with several goals: 1) We now call a callback instead of assuming the caller has a single child to paint. This change will let us handle render objects that wish to paint more than one child. 2) We now avoid creating lots of empty picture layers because we don't eagerly start recording pictures. Instead, we wait for the first caller to touch the canvas before creating the picture recorder. 3) We now are more consistent about which values have incorporated the painting offset.
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.
