batMobile function

void batMobile(
  1. dynamic batman,
  2. dynamic robin,
  3. dynamic joker
)

Maybe some class, which includes these 3 methods. Mobile must be... but what would it do ?

Implementation

void batMobile(var batman, var robin, var joker) {
  batman();
  robin();
  joker();
  print('----------  batMobile might say no to 3.  Joker');
}
