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.

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

inherited

toStringShort() → String

Static Methods

expose(BuildContext context, dynamic data) → dynamic

同种类型只能被expose一次。若多次expose, 在AppProvider.get()时默认取最早expose的数据

get<T>(BuildContext context) → T?

remove(BuildContext context, dynamic data) → dynamic

watch<T extends IController, K extends Level>(IController controller) → T?

watchLevel<T extends IController, K extends Level, J extends Level>(IController controller) → T?

T 被监听页面的IController K 被监听页面的level J 当前页面Level 即监听T页面的K Level, 若有变动，处罚当前页面的J刷新
