int duration

Duration expressed in number of frames.

Implementation

int get duration => _duration;
void duration=(int value)

Change the _duration field value. durationChanged will be invoked only if the field's value has changed.

Implementation

set duration(int value) {
  if (_duration == value) {
    return;
  }
  int from = _duration;
  _duration = value;
  if (hasValidated) {
    durationChanged(from, value);
  }
}
