ProviderSidecar<EX> class
abstract
对ChangeNotifier进行包装 EX 抛出的异常类型, 便于UI代码展示错误信息
- Inheritance
-
- Object
- ChangeNotifier
- ProviderSidecar
Constructors
- ProviderSidecar({SidecarState state = SidecarState.uninitialized, String msg = 'Init with Constructor', EX onCatch(dynamic e, StackTrace s)?})
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- msg ↔ String
-
getter/setter pair
- onCatch → (EX Function(dynamic e, StackTrace s)?)
-
0.1
构造方法final - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- state ↔ SidecarState
-
0.2 配置核心
状态变量或get方法getter/setter pair
Methods
-
actInitializing(
{String m = "初始化...", dynamic onInitializing()?}) → Future< EX?> -
0.4 配置
actXxx方法 act ---------------------------------------------------------------------- 状态设为 正在初始化 onInitializing 函数内应当执行耗时的初始化代码 -
actWrapper(
[Function? action]) → Future< EX?> - 统一处理异常
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
onInitializing(
) → dynamic - 完成后需要手动调用 setInitialized
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
reqWrapper<
T> (T? onAccess(), {List< SidecarState> ? accContain, List<SidecarState> ? rejContain, bool accCustom()?, T? onReject()?}) → T? - 处理前置触发条件, 防抖节流等 可选条件参数最多使用1个, 如果使用多个,则只有首个非空参数逻辑生效 如果不适用任何参数,则默认通过
-
setInitialized<
T> ([String m = "初始化完成", T before()?]) → T? -
setInitializing<
T> ([String m = "初始化...", T before()?]) → T? -
setUninitialized<
T> ([String m = "未初始化", T before()?]) → T? -
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Properties
- log → dynamic
-
no setter
Static Methods
-
setLogger(
dynamic log(Object? message, [Object? error, StackTrace? stackTrace])) → dynamic
