如何导入 flutter（不是飞镖）collections 库？

Question

I'm able to import

import 'dart:collection';

But that's not the same as the library with an API here: https://api.flutter.dev/flutter/package-collection_collection/package-collection_collection-library.html

I can't seem to figure out the correct uri for import this library, and can't find any thing on the web or the api about this.

Answer 1

import 'package:collection/collection.dart';
