TickerMode class Null safety

Enables or disables tickers (and thus animation controllers) in the widget subtree.

This only works if AnimationController objects are created using widget-aware ticker providers. For example, using a TickerProviderStateMixin or a SingleTickerProviderStateMixin.

Constructors

TickerMode({Key? key, required bool enabled, required Widget child}): Creates a widget that enables or disables tickers.
const

child → Widget: The widget below this widget in the tree.
final
enabled → bool: The requested ticker mode for this subtree.
final
hashCode → int: The hash code for this object.
nonVirtual">@nonVirtualread-onlyinherited
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
runtimeType → Type: A representation of the runtime type of the object.
read-onlyinherited

createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<TickerMode>: Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
protected">@protectedinherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode: Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String: A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.

operator ==(Object other) → bool: The equality operator.

getNotifier(BuildContext context) → ValueNotifier<bool>: Obtains a ValueNotifier from the TickerMode surrounding the context, which indicates whether tickers are enabled in the given subtree.
of(BuildContext context) → bool: Whether tickers in the given subtree should be enabled or disabled.
