Description:

task util

This is a library for concurrent task processing, specializing in various concurrent scenarios.
Features #

Single task mutually exclusive.
Multitasking

Getting started #
start using the package.
Usage #
import 'package:task_util/task_util.dart';

void main() async {
/// Individual task management.
SingleTaskPool singleTaskPool = SingleTaskPool.builder();
List<String> result = [];
String firstTaskPrint = "foo";
String secondTaskPrint = "bar";
DateTime startTime = DateTime.now();
await Future.wait([
singleTaskPool.start(() async {
await Future.delayed(Duration(seconds: 1));
result.add(firstTaskPrint);
}),
singleTaskPool.start(() async {
await Future.delayed(Duration(seconds: 1));
result.add(secondTaskPrint);
}),
]);

/// Took more than 2 seconds.Even though the execution is concurrent, it still becomes a serial execution
print(DateTime.now().microsecondsSinceEpoch - startTime.microsecondsSinceEpoch);

/// Multiple task result reuse
final multiplexTaskPool = MultiplexTaskPool.builder();
List<String> multipleResult = await Future.wait([
multiplexTaskPool.start<String>(() async {
return "1";
}),
multiplexTaskPool.start<String>(() async {
return "2";
}),
multiplexTaskPool.start<String>(() async {
return "3";
}),
]);

/// print: ['1', '1', '1']。
/// Although 3 tasks are concurrent, only the first task is executed and the result is returned to the task to be executed later.
print(multipleResult);
