GlowingOverscrollIndicator constructor

const GlowingOverscrollIndicator({Key key, bool showLeading: true, bool showTrailing: true, @required AxisDirection axisDirection, @required Color color, ScrollNotificationPredicate notificationPredicate: defaultScrollNotificationPredicate, Widget child })

Creates a visual indication that a scroll view has overscrolled.

In order for this widget to display an overscroll indication, the child widget must contain a widget that generates a ScrollNotification, such as a ListView or a GridView.

The showLeading, showTrailing, axisDirection, color, and notificationPredicate arguments must not be null.

Implementation 

const GlowingOverscrollIndicator({
  Key key,
  this.showLeading = true,
  this.showTrailing = true,
  @required this.axisDirection,
  @required this.color,
  this.notificationPredicate = defaultScrollNotificationPredicate,
  this.child,
}) : assert(showLeading != null),
     assert(showTrailing != null),
     assert(axisDirection != null),
     assert(color != null),
     assert(notificationPredicate != null),
     super(key: key);
