Hi the enum concept is introduced in Switch condition.
The example enum:

enum Weather {
  sunny,
  snowy,
  cloudy,
  rainy,
}

has to be declared outside main function. It has error if I put it inside main function, is there a simple reason to explain this?

In Dart, a class cannot be defined in a function. An enum is a class.
