map<TResult extends Object?> method

@optionalTypeArgs TResult map<TResult extends Object?>({ required TResult invalidPath(HaudiotaggerError_InvalidPath value), required TResult noTags(HaudiotaggerError_NoTags value), required TResult openFile(HaudiotaggerError_OpenFile value), required TResult write(HaudiotaggerError_Write 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(HaudiotaggerError_InvalidPath value) invalidPath,
  required TResult Function(HaudiotaggerError_NoTags value) noTags,
  required TResult Function(HaudiotaggerError_OpenFile value) openFile,
  required TResult Function(HaudiotaggerError_Write value) write,
}) {
  final _that = this;
  switch (_that) {
    case HaudiotaggerError_InvalidPath():
      return invalidPath(_that);
    case HaudiotaggerError_NoTags():
      return noTags(_that);
    case HaudiotaggerError_OpenFile():
      return openFile(_that);
    case HaudiotaggerError_Write():
      return write(_that);
  }
