[@LeoTechy]

How do you create an instance of that class with no initialization. class with required fields before it used to be ClassName name = new ClassName(); but now it doesn't work

[@Codemycom]

Don't use the constructor, instead build a method to assign the things later.

For a model/data class, I'd rather do this; enum Sex {male, female} class Person{ final String name; final Sex sex; final int age; const Person({required this.name, required this.sex, required this. age}); /// Create copyWith() method here /// Create toMap() method here /// Create factory Person.fromMap() @override String toString() => 'Person(name: $name, sex: $sex, age: $age)'; } final person = Person(name: 'John', sex: Sex.male, age: 44); print(person); Dart should figure out what type the variable "person" is.

Why is String with uppercase S but all other types are lower case?

[@MTPMCMEDIA]

Basically, if you watch closely, you will notice that all the iterables start with a cap. Like List, Map, String, etc.
