maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>({
  1. TResult refVariant(
    1. LexRefVariant data
    )?,
  2. TResult object(
    1. LexObject data
    )?,
  3. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>({TResult Function( LexRefVariant data)?  refVariant,TResult Function( LexObject data)?  object,required TResult orElse(),}) {final _that = this;
switch (_that) {
case ULexXrpcSchemaRefVariant() when refVariant != null:
return refVariant(_that.data);case ULexXrpcSchemaObject() when object != null:
return object(_that.data);case _:
  return orElse();

}
