WTF dart?

main.dart

void main() {
  // Careful with filled it will use the same object
  //final _map = List.filled(10, List.filled(10, 0));
  final _map = List.generate(10, (_) => List.generate(10, (_) => 0));
  
  _map[1][1] = 1;
  _map[0][1] = 1;
  
  print('This is madness ${_map[1][2] == 1 ? 'yes' : 'no'} '); 
  
  _map.forEach(print);
}
