[Dart] final vs const

Posted 2022-08-05 answer1215

void main() 
  var a = 1;
  print(a);

  int b = 2;
  print(b);

  final c = ‘Hello‘;
  // c = ‘Hello again‘; // Uncomment to throw
  print(c);

  const d = ‘World‘;
  print(d);

 

If we attempt to reset ‘final‘ to a different value, we will get an error. The difference in practice between const and final is you use final when certain instance variables belong into classes.
