I solved the json thing here the code

  Future getData() async {
      _events = {};
      final response = await http.get("http://muditacenter.com/aplikasi/get_data.php");
      var jsonData = json.decode(response.body);
      for(var i = 0; i < jsonData.length; i++) {
        _events[DateTime.parse(jsonData[i]['tanggal'])] = jsonData[i]['judul'];
       }
  }

JSON EXAMPLE :

[{"tanggal":"2019-04-07","judul":["Cheng Beng"]},{"tanggal":"2019-04-21","judul":["Asthasila222 (八關齋戒).\r\n","Kegitan lainnya","Kegitan lainnya 2"]}]
