findOne method

@override Future<Map<String, dynamic>> findOne([ Map<String, dynamic>? params, String errorMessage = 'No record was found matching the given query.' ])

Retrieves the first object from the result of calling index with the given params.

If the result of index is null, OR an empty Iterable, a 404 AngelHttpException will be thrown.

If the result is both non-null and NOT an Iterable, it will be returned as-is.

If the result is a non-empty Iterable, findOne will return it.first, where it is the aforementioned Iterable.

A custom errorMessage may be provided.

Implementation

@override
Future<Map<String, dynamic>> findOne(
    [Map<String, dynamic>? params,
    String errorMessage =
        'No record was found matching the given query.']) async {
  var result =
      (await store.findFirst(database, finder: _makeQuery(params)))?.value;
  if (result == null) {
    return {};
  }

  return result;
}
