maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>({ TResult html(String html)?, TResult json(Object data)?, TResult plainText(String text)?, 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( String html)?  html,TResult Function( Object data)?  json,TResult Function( String text)?  plainText,required TResult orElse(),}) {final _that = this;
switch (_that) {
case HtmlApiResultBody() when html != null:
return html(_that.html);case JsonApiResultBody() when json != null:
return json(_that.data);case PlainTextApiResultBody() when plainText != null:
return plainText(_that.text);case _:
  return orElse();

}
