resolve method

@override Future<String> resolve()

Gets the data from the remote source and returns the raw data. The returned string will be saved in the cache and decoded using fromJson.

Implementation

@override
Future<String> resolve() async {
  try {
    final request = RepositoryHttpRequest(url: endpoint);
    final response = await client.get(request: request);

    /// If the endpoint returns a 200, add the data to the stream
    /// and cache it
    if (successfulCondition(response.statusCode, response.body)) {
      final result = response.body;

      return result;
    } else {
      Repository.logger(
        'Repository($name): Failed to resolve [$endpoint]. '
        'status code: ${response.statusCode}',
      );
      await onErrorStatusCode(response.statusCode);

      throw UnexpectedStatusCodeException(
        sent: request,
        received: response,
      );
    }
  } catch (exception) {
    /// if the user is offline, the request will fail.
    /// if [onSocketException] is not null, we call it.
    /// if [onSocketException] is null, we rethrow the exception.
    Repository.logger(
      'Repository($name): throws [${exception.runtimeType}].',
      level: RepositoryLoggingLevel.warning,
    );

    if (exception is Exception) {
      await onSocketException(exception);
    }

    rethrow;
  }
}
