collection_ext 0.0.1

Extension functions for Dart collections.

collection_ext

A set of extension functions for Dart collections, designed in the purpose of making it easier to write functional-style, concise dart codes.

Working on an Iterable for example, with collection_ext, we can write:

iterable.forEachIndexed((i, x) => /* use index i & element x */)

instead of:

var i = 0;
for (var x in iterable) {
  // use index i & element x
  i++;
}

👉 See API Docs for more details

Usage

Import all extension functions at once:

import 'package:collection_ext/all.dart';

Column(
  children: getItems()
    .nonNull
    .mapIndexed((i, item) => Text("#$i ${item.title}"))
    .asList(),
)

Or you can import the needed module only, for example:

import 'package:collection_ext/iterables.dart';

final sum = [2, 4, 6].foldRight(0, (acc, x) => acc + x);

Available Modules

• Extensions to Iterables
