AsyncMemoizer in Dart/Flutter

Question

How do you memoize your futures? I am using a FutureBuilder that gets items data by some params.

I found here a suggestion to use AsyncMemoizer, however it looks like it's missing from the dart:async package.

Are there alternatives?

`AsyncMemoizer` is part of [`package:async`](https://pub.dev/packages/async), not `dart:async`. — jamesdlin, Apr 18 '20 at 22:58

First add dependency:

dart pub add async

Then import and use it:

import 'package:async/async.dart';
...
final _memoizer = AsyncMemoizer();
