Functions
-
debounce<T>(GetListenable<T> listener, WorkerCallback<T> callback, {Duration? time, Function? onError, void onDone()?, bool? cancelOnError})
→ Worker
-
debounce is similar to interval, but sends the last value.
Useful for Anti DDos, every time the user stops typing for 1 second,
for instance.
When
listener emits the last "value", when time hits,
it calls callback with the last "value" emitted.
-
ever<T>(GetListenable<T> listener, WorkerCallback<T> callback, {dynamic condition = true, Function? onError, void onDone()?, bool? cancelOnError})
→ Worker
-
Called every time
listener changes. As long as the condition
returns true.
-
everAll(List<RxInterface> listeners, WorkerCallback callback, {dynamic condition = true, Function? onError, void onDone()?, bool? cancelOnError})
→ Worker
-
Similar to ever, but takes a list of
listeners, the condition
for the callback is common to all listeners,
and the callback is executed to each one of them. The Worker is
common to all, so worker.dispose() will cancel all streams.
-
interval<T>(GetListenable<T> listener, WorkerCallback<T> callback, {Duration time = const Duration(seconds: 1), dynamic condition = true, Function? onError, void onDone()?, bool? cancelOnError})
→ Worker
-
Ignore all changes in
listener during time (1 sec by default) or until
condition is met (can be a bool expression or a bool Function()),
It brings the 1st "value" since the period of time, so
if you click a counter button 3 times in 1 sec, it will show you "1"
(after 1 sec of the first press)
click counter 3 times in 1 sec, it will show you "4" (after 1 sec)
click counter 2 times in 1 sec, it will show you "7" (after 1 sec).
-
once<T>(GetListenable<T> listener, WorkerCallback<T> callback, {dynamic condition = true, Function? onError, void onDone()?, bool? cancelOnError})
→ Worker
-
once() will execute only 1 time when condition is met and cancel
the subscription to the listener stream right after that.
condition defines when callback is called, and
can be a bool or a bool Function().
