Panic a flutter app when you really need it.

  static Future<Result<DiscoverResponse?, NetworkError>> fetchDiscover() async {
    final response = await _client.get(
      Uri.parse('$baseUrl/discover/movie?api_key=$themoviedbApiKey&page=1'),
    );

    if (response.statusCode == 200) {
      // Panic app if some important parameters are missed e.g.,
      // some field in a Header or in a Body.
      if (!response.headers.containsKey('MY MISSING KEY')) {
        panic.app();
      }
      return Success(DiscoverResponse.fromJson(response.body));
    } else {
      throw NetworkError(response.statusCode);
    }
  }
