Widget? child

The widget below this widget in the tree.

The overscroll indicator will paint on top of this child. This child (and its subtree) should include a source of ScrollNotification notifications.

Typically a GlowingOverscrollIndicator is created by a ScrollBehavior.buildOverscrollIndicator method, in which case the child is usually the one provided as an argument to that method.
