getBusTimeTable method

Implementation

Future<Map<String, List<BusTimeTable>>> getBusTimeTable() async {
  var response = await fetch("busTimetable");
  Map<String, List<BusTimeTable>> retmap = {};
  Map<String, dynamic> tablemap = response != null
      ? (json.decode(response.body) as Map<String, dynamic>)
      : [];
  tablemap.forEach((key, value) {
    List<dynamic> b = value["stops"];
    List<BusTimeTable> bl =
        b.map((element) => BusTimeTable.fromJson(element)).toList();
    retmap[key] = bl;
  });
  return retmap;
}
