fetchCities method

Future<List<Cities>> fetchCities(int stateId)

Fetches the list of cities for a given state ID.

Makes a GET request to https://chat.jobkar.in/cities/{stateId}. Parses the JSON response, extracts the list of city data, and converts each JSON object into an AwesomeCity model.

Returns a Future<List<AwesomeCity>> that completes with the list of cities. Throws an Exception if the request fails.

Implementation

Future<List<Cities>> fetchCities(int stateId) async {
  // Make GET request to cities endpoint with stateId path parameter
  final response = await http.get(
    Uri.parse('$baseUrl/cities/$stateId'),
    headers: {
      "Access-Control-Allow-Origin": "*",
      "Access-Control-Allow-Methods": "GET, POST, OPTIONS",
      "Content-Type": "application/json",
    },
  );

  // Check if the response was successful
  if (response.statusCode == 200) {
    // Decode JSON and convert list to AwesomeCity instances
    final List data = json.decode(response.body)['data'];
    return data.map((e) => Cities.fromJson(e)).toList();
  } else {
    // Throw error if the request failed
    throw Exception('Failed to load cities');
  }
}
