<itemvalue="Describes how [Scrollable] widgets should behave. {@template flutter.widgets.scrollBehavior} Used by [ScrollConfiguration] to configure the [Scrollable] widgets in a subtree. This class can be extended to further customize a [ScrollBehavior] for a subtree. For example, overriding [ScrollBehavior.getScrollPhysics] sets the default [ScrollPhysics] for [Scrollable]s that inherit this [ScrollConfiguration]. Overriding [ScrollBehavior.buildOverscrollIndicator] can be used to add or change the default [GlowingOverscrollIndicator] decoration, while [ScrollBehavior.buildScrollbar] can be changed to modify the default [Scrollbar]. When looking to easily toggle the default decorations, you can use [ScrollBehavior.copyWith] instead of creating your own [ScrollBehavior] class. The `scrollbar` and `overscrollIndicator` flags can turn these decorations off. {@endtemplate} See also: [ScrollConfiguration], the inherited widget that controls how [Scrollable] widgets behave in a subtree. @immutable"/>
