just_debounce_it

A simple debounce library. Supports debouncing by function and stream debouncing.

import 'package:just_debounce_it/just_debounce_it.dart';

Debounce.milliseconds(1000, print, ["Debounce World!"]);

Static methods

There are three methods available for debouncing. All methods differ only by the first parameter used to specify timeout values in different formats. The target Function provided must be the same object every time Debounce is called.

Debounce.seconds(int timeoutSeconds, 
    Function target,
    [List<dynamic> positionalArguments, 
    Map<Symbol, dynamic> namedArguments])

Debounce.milliseconds(int timeoutMs, 
    Function target,
    [List<dynamic> positionalArguments, 
    Map<Symbol, dynamic> namedArguments])

Debounce.duration(Duration timeout, 
    Function target,
    [List<dynamic> positionalArguments, 
    Map<Symbol, dynamic> namedArguments])

To immediately dispatch a target that has previously been debounced, use runAndClear. Optional args can be provided to override the debounced arguments:

Debounce.runAndClear( 
    Function target,
    [List<dynamic> positionalArguments, 
    Map<Symbol, dynamic> namedArguments])

To clear a debounced target:

Debounce.clear( 
    Function target,
    [List<dynamic> positionalArguments, 
    Map<Symbol, dynamic> namedArguments])

Stream Debouncing

Use DebounceStreamTransfomer to debounce any stream by a specified duration.

DebounceStreamTransfomer(Duration timeout)

DebounceStreamTransfomer.seconds(int timeoutSeconds)

DebounceStreamTransfomer.milliseconds(int timeoutMs)

Stream debounceStream(Stream input) => input.transform(DebounceStreamTransfomer.seconds(1));

Example

A quick demonstration can be found in the example directory. To run the example:

pub run example/main.dart
