Extension on List to directly map a list, without calling toList.

Extension on List to directly map a list, without calling toList.

Getting started

Always chaining map and toList when you want to map a List is tiring, especially in a Flutter app development. Most of the time, we know we just want to map our list into another list, not into a lazy Iterable.

This simple extension simplify the process.

Usage

Add package map_to_list into project dependencies:

dart pub add map_to_list

And import the package into your project file:

import 'package:map_to_list/map_to_list.dart';

Then you could call a single mapToList:

final list = [1, 2, 3, 4, 5];
final mapped = list.mapToList((value) => value * value);

Instead of always chaining map and toList:

final list = [1, 2, 3, 4, 5];
final squared = list.map((value) => value * value).toList();
