Methods
-
asStream(
) → Stream< T> -
Creates a Stream containing the result of this future.
override
-
cancel(
) → void - 取消正在进行的任务
-
catchError(
Function onError, {bool test(Object error)?}) → Future< T> -
Handles errors emitted by this Future.
override
-
message(
) → Future< String?> - 返回WorkData.message无论任务成功或失败
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
requiredResultOrThrow(
[FutureOr< void> onDo(D value)?]) → Future<D> - 获取非空结果或抛出异常
-
requiredResultOrThrowMessage(
[FutureOr< void> onDo(D value)?]) → Future<D> - 获取非空结果或抛出纯字符串异常
-
result(
) → Future< D?> - 返回任务执行结果WorkData.result,无论任务成功或失败
-
resultOrThrow(
[FutureOr< void> onDo(D? value)?]) → Future<D?> - 获取结果或抛出异常
-
resultOrThrowMessage(
[FutureOr< void> onDo(D? value)?]) → Future<D?> - 获取结果或抛出纯字符串异常
-
success(
) → Future< bool> - 返回任务执行结果的未来
-
then<
R> (FutureOr< R> onValue(T value), {Function? onError}) → Future<R> -
Register callbacks to be called when this future completes.
override
-
thenFailed<
R> (FutureOr< R> onValue(T value)) → Future<R?> -
仅当Work失败时,即WorkData.success为false时才执行
onValue
-
thenResult<
R> (FutureOr< R> onValue(D? value)) → Future<R?> -
Work.start().then((data) => data.result)
的快捷方式 它会等待Work.start完成后执行onValue
参数为WorkData.result。 -
thenSuccessful<
R> (FutureOr< R> onValue(T value)) → Future<R?> -
仅当Work成功时,即WorkData.success为true时才执行
onValue
-
timeout(
Duration timeLimit, {FutureOr< T> onTimeout()?}) → Future<T> -
Stop waiting for this future after
timeLimit
has passed.override -
toString(
) → String -
A string representation of this object.
override
-
whenComplete(
FutureOr< void> action()) → Future<T> -
Registers a function to be called when this future completes.
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
