map<TResult extends Object?> method

@optionalTypeArgs TResult map<TResult extends Object?>({ required TResult bytes(BytesModel value), required TResult kb(KbModel value), required TResult mb(MbModel value), required TResult gb(GbModel value), required TResult tb(TbModel value), })

A switch-like method, using callbacks.

Callbacks receives the raw object, upcasted. It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case final Subclass2 value:
    return ...;
}

Implementation

@optionalTypeArgs
TResult map<TResult extends Object?>({
  required TResult Function(BytesModel value) bytes,
  required TResult Function(KbModel value) kb,
  required TResult Function(MbModel value) mb,
  required TResult Function(GbModel value) gb,
  required TResult Function(TbModel value) tb,
}) {
  final _that = this;
  switch (_that) {
    case BytesModel():
      return bytes(_that);
    case KbModel():
      return kb(_that);
    case MbModel():
      return mb(_that);
    case GbModel():
      return gb(_that);
    case TbModel():
      return tb(_that);
  }
}
