  1. ViewModel HsViewModel
Inheritance
Mixed-in types
Available extensions

Constructors

HsViewModel.new()

Properties

hashCode → int
The hash code for this object.
no setterinherited
initValue → M?
initValue 初始值 如果不想设置初始值, 请return null; 如果要需要异步初始化, 请return null, 并覆写onCreate 函数
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stream → Stream<M>
no setterinherited
subject → StreamController<M>
no setterinherited
value → M
no setterinherited
valueOrNull → M?
如果没有初始值, 则value可能为null,使用valueOrNull避免抛出异常
no setterinherited

Methods

combineStream(List<BaseHiveState>? combines) → CombineLatestStream<dynamic, List>
合并多个HiveState, 任意一个HiveState更新,都会产生新的event 返回值: List, 按顺序返回每一个Stream的最新的值; 由于每个Stream的类型可能不同, 所以类型为List
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.
override
dispose() → void
============== 以下是高级功能, 一般情况下无需使用 ============== 释放内存
inherited
logger(String message, {DateTime? time, int? sequenceNumber, int level = 0, String? name, Zone? zone, Object? error, StackTrace? stackTrace}) → dynamic
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onCreate({M? initValue}) → StreamController<M>
通过覆写onCreate,可以实现在首次创建subject时设置初始数据T实例 但如果初始值不是固定值, 则需要通过BaseHiveState.init设置初始值T实例 注意: 一般情况下, 是在Widget的initState方法中调用 put 值进行初始化;
inherited
put(M value) → BaseHiveState<M>
inherited
putError(Object e, [StackTrace? s]) → BaseHiveState<M>
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
toProvider({Key? key, dynamic onCreated(VM vm)?, Dispose<VM>? dispose, bool? lazy, TransitionBuilder? builder, Widget? child}) → dynamic

Available on HsViewModel<HsModel>, provided by the HsViewModelX extension

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 brief description of this object, usually just the runtimeType and the hashCode.
inherited
update(FutureOr<M> update(M old), {dynamic onError(Object e, StackTrace s)?}) → Future<void>
执行一个异步操作, 并更新状态 不建议对本方法进行二次包装, 因此返回值强制为 void
inherited
updateOrNull(FutureOr<M> update(M? old), {dynamic onError(Object e, StackTrace s)?}) → Future<void>
if State init value is null, you can use updateOrNull
inherited
valueToString(M? value) → String
putError中, 将会打印model值value 覆写本函数, 返回需要打印的内容
inherited

Operators

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