CupertinoPageScaffold class Null safety

Implements a single iOS application page's layout.

The scaffold lays out the navigation bar on top and the content between or behind the navigation bar.

When tapping a status bar at the top of the CupertinoPageScaffold, an animation will complete for the current primary ScrollView, scrolling to the beginning. This is done using the PrimaryScrollController that encloses the ScrollView. The ScrollView.primary flag is used to connect a ScrollView to the enclosing PrimaryScrollController.

This example shows a CupertinoPageScaffold with a ListView as a child. The CupertinoButton is connected to a callback that increments a counter. The backgroundColor can be changed.
To create a local project with this code sample, run:
flutter create --sample=cupertino.CupertinoPageScaffold.1 mysample
