Constructors

Methods
- build(
BuildContext context) → Widget - Override this method to build widgets that depend on the state of the listenable (e.g., the current value of the animation). override
- createElement(
) → StatefulElement - Creates a StatefulElement to manage this widget's location in the tree. inherited
- createState(
) → State< AnimatedWidget> - Subclasses typically do not override this method. inherited
- debugDescribeChildren(
) → List< DiagnosticsNode> - Returns a list of DiagnosticsNode objects describing this node's children. inherited
- debugFillProperties(
DiagnosticPropertiesBuilder properties) → void - Add additional properties associated with the node. inherited
- noSuchMethod(
Invocation invocation) → dynamic - Invoked when a nonexistent 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, int wrapWidth = 65}) → 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. inherited
Operators
- operator ==(
Object other) → bool - The equality operator. inherited
