easy debouncer

debouncer #
An easy-to-use method call debouncer package for Dart/Flutter.
Debouncing is needed when there is a possibility of multiple calls to a method being made within a short duration of each other, and it's desirable that only the last of those calls actually invoke the target method.
So basically each call starts a timer, and if another call happens before the timer executes, the timer is reset and starts waiting for the desired duration again. When the timer finally does time out, the target method is invoked.
Usage #
Debouncing
Use the debouncer by calling debounce:
Debouncer.debounce(
'my-debouncer', // <-- An ID for this particular debouncer
Duration(milliseconds: 500), // <-- The debounce duration
() => myMethod() // <-- The target method
);
copied to clipboard
The above call will invoke myMethod() after 500 ms, unless another call to debounce() with the same tag is made within 500 ms. A tag identifies this particular debouncer, which means you can have multiple different debouncers running concurrently and independent of each other.
Cancelling a debouncer
A debouncer which hasn't yet executed its target function can be called by calling cancel() with the debouncers tag:
Debouncer.cancel('my-debouncer');
copied to clipboard
To cancel all active debouncers, call cancelAll():
Debouncer.cancelAll();
copied to clipboard
Counting active debouncers
You can get the number of active debouncers (debouncers which haven't yet executed their target methods) by calling count():
print('Active debouncers: ${Debouncer.count()}');
copied to clipboard
Fire a debouncer target function manually
If you need to fire the target function of a debouncer before the timer executes, you can call fire():
Debouncer.fire('my-debouncer');
copied to clipboard
This will execute the debouncers target function, but the debounce timer will keep running unless you also call cancel().
