Here you can find an example, the key - using map.entries

class Person {
  final String name;
  final int age;

  Person(this.name, this.age);
}

void test() {
  final map = <String, int>{"Jack": 23, "Adam": 27, "Katherin": 25};

  final list = map.entries.map((entry) => Person(entry.key, entry.value)).toList();
}

If you don't want to use Person class, you can use the package with tuple https://pub.dev/packages/tuple
