An example memoize function implementation in Dart.
A simple usage example:
import 'package:memoize/memoize.dart';
main() {
var uniqueId = 0;
final generate = (String prefix) => ++uniqueId;
final memoizedCalc = memoize(generate);
var val1 = memoizedCalc('item');
var val2 = memoizedCalc('item');
print('equal: ${val1 == val2}'); // will be true
}
