A set of Future helper functions (mostly) compatible with Node.js counterpart Promise libraries such as Bluebird. Supports concurrency & cancellation.
The library exposes static methods under a single class F4 (pronounced
Future) to avoid accendential pollution of the global namespace, maybe a bit
of an anti-pattern in Dart land, then again maybe some of helpers should have
been natively supported by Dart itself.
Currently supports the following helper methods: all, map, chain, props,
one, forEach, create, and reflect.
The AbortController class exposes means for cancellation of Futures and is
compatible with its Fetch API counterpart.
PS: Not tested in production, written over a weekend for me to learn Dart, PRs are welcome.
A simple usage example:
import 'package:f4/f4.dart';
main() async
{
final r = await F4.map([1,2,3,4], (int i)=>Future.value(i), concurrency:2);
print(r); //[1,2,3,4]
}Complete usage example under /example.
