[Dart] #3.3 Optional Positional Parameters

String sayHello(String name, int age, [String? country = 'cuba']) => 'Hello $name, you are $age years old from $country';

void main(){
	sayHello('nico',12);
}

 

country is not required, and default value is set.

 

Nico doesn't use this a lot! like less than ten times.

 

Nico uses 'named' parameters a lot !!
