SelectionArea class Null safety

A widget that introduces an area for user selections with adaptive selection controls.

This widget creates a SelectableRegion with platform-adaptive selection controls.

Flutter widgets are not selectable by default. To enable selection for a specific screen, consider wrapping the body of the Route with a SelectionArea.

This example shows how to make a screen selectable.
To create a local project with this code sample, run:
flutter create --sample=material.SelectionArea.1 mysample
