How to construct a class with named args from a map?
By creating a constructor for that matter:
class Person { final int age; final String name; const Person({ @required this.age, @required this.name, }); Person.fromMap(Map<String, dynamic> map) : age = map['age'], name = map['name'];}You can also assign in the constructor body if you prefer, that makes it more clear if you have more fields.
