dispose method

void dispose([ bool evict = false ])

Implementation

void dispose([bool evict = false]) {
  if (evict) {
    try {
      // ignore: return_type_invalid_for_catch_error
      imageProvider.evict().catchError(print);
    } catch (e) {
      // this may be never called because catchError will handle errors, however
      // we want to avoid random crashes like in #444 / #536
      print(e);
    }
  }

  animationController?.removeStatusListener(_onAnimateEnd);
  animationController?.dispose();
