ListCallback class

ListCallback

ListCallback is a helper class to create callbacks with multiple arguments.

Converts a normal event of type List<dynamic> into its individual arguments, which it then validates each argument type before calling the callback.

final emitter = EventEmitter();

emitter.on('message', ListCallback.args2((String text, int number) {
  print('String: $text, Number: $number');
}));

emitter.emit('message', ['Hello World', 123]);
