Methods

createElement() → CoreContext

Creates a StatefulElement to manage this widget's location in the tree.

override

createState() → CoreState<CoreWidget>

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.

inherited

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

inherited

init(CoreContext context) → void

Initial widget initialization. Use your mixins here.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onDependencyChanged(CoreContext context) → void

Called whenever dependency of Widget is changed. Check State.didChangeDependencies for more info. Just callback from State.

onDispose() → void

onInit(Map args, CoreContext context) → void

Called right after initState and before build. context is here fully usable without restrictions.

onUpdate(CoreContext context, CoreWidget oldWidget) → void

Called whenever Widget requests update. Check State.didUpdateWidget for more info. Just callback from State.

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.
