    http.Response response = await http.get(Uri.parse(url), headers: headers);

    // Check if the response status code is 200 (OK).
    if (response.statusCode == 200) {
      // If successful, decode the JSON response and return the data.
      return json.decode(response.body);
    } else {
      // If not successful, throw an exception with an informative error message.
      throw Exception(
