StreamLazyMixin<T> mixin

pause的对象不会立即进入dirty状态,会在一个新的数据被添加进来后, 设为dirty状态,只有在dirty状态下，resume才有可能调用_childResume, 获取新数据

add(T data) → void
addError(Object error, StackTrace stackTrace) → void
close() → void
dispose() → void: 没有监听者调用一次
listen(void onData(T event)?, {Function? onError, void onDone()?, bool? cancelOnError, bool async = false}) → StreamSubscription<T>
moveToDirty() → void
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

notifyClient() → void
onListen(StreamSubscriptionUnit<T> child) → void
resetDispose() → void
toString() → String: A string representation of this object.

trigger({StreamSubscriptionUnit<T>? self}) → void: 如果isPaused状态没有改变,resume时有可能发生这种情况手动为self更新数据
