BlocStateListener class - bloc library

Constructors

BlocStateListener({required List<BlocStateListenerBinder<BlocState>> stateBinders, Widget? child, T? bloc})

bloc → T?: The bloc whose state will be listened to. Whenever the bloc's state changes, listener will be invoked.
finalinherited
child → Widget?: The widget which will be rendered as a descendant of the BlocListenerBase.
finalinherited
hashCode → int: The hash code for this object.
no setterinherited
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
listener → BlocWidgetListener<BlocState>: The BlocWidgetListener which will be called on every state change. This listener should be used for any code which needs to execute in response to a state change.
finalinherited
listenWhen → BlocListenerCondition<BlocState>?: An optional listenWhen can be implemented for more granular control over when listener is called. listenWhen will be invoked on each bloc state change. listenWhen takes the previous state and current state and must return a bool which determines whether or not the listener function will be invoked. The previous state will be initialized to the state of the bloc when the BlocListener is initialized. listenWhen is optional and if omitted, it will default to true.
finalinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

createElement() → SingleChildStatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → SingleChildState<BlocListenerBase<T, BlocState>>: Creates the mutable state for this widget at a given location in the tree.
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}) → 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.
