    return  http.post(
      Uri.parse('https://laravelsyd-fypfinalver.herokuapp.com/getBusService'),

      headers: <String, String>{
        'Content-Type': 'application/json; charset=UTF-8',
      },
      body: { 
        jsonEncode({'bus_stop_id': busCode})
      },
        if (response.statusCode == 200) {
          final List<dynamic> data = json.decode(response.body);
          dataList = List<Map<String, dynamic>>.from(data);
          setState(() {// Update the state to trigger a rebuild with the fetched data
             dataList = List<Map<String, dynamic>>.from(data);
          },);
        } else {
          print (response.statusCode);

        );
  }

Answer 1

Please try this code

  Future<http.Response> fetchData(String query) async {
var response = await http.post(
    "https://laravelsyd-fypfinalver.herokuapp.com/getBusService",
    headers: <String, String>{
      'Content-Type': 'application/json; charset=UTF-8',
    },
    body: jsonEncode({'bus_stop_id': busCode}));

if (response.statusCode == 200) {
  final List<dynamic> data = json.decode(response.body);
  dataList = List<Map<String, dynamic>>.from(data);
  setState(
    () {
      // Update the state to trigger a rebuild with the fetched data
      dataList = List<Map<String, dynamic>>.from(data);
    },
  );
} else {
  print(response.statusCode);
}}
