// ...
  Future<BsSelectBoxResponse> selectApi(Map<String, String> params) async {
    Uri url = Uri.http('localhost', 'api-json.php', params);
    Response response = await http.get(url);
    if(response.statusCode == 200) {
      List json = convert.jsonDecode(response.body);
      return BsSelectBoxResponse.createFromJson(json);
    }

    return BsSelectBoxResponse(options: []);
  }
// ...

Json response data

[
  {
    "value":"1",
    "text":"Tipe 01",
    "typecd":"TP01"},
  {
    "value":"2",
    "text":"Type 02",
    "typecd":"TP02"
  }
]

Note

• createFromJson is automatically put response data value, but you cant change it with define manual
• If you want to make typecd as value of option, use value parameters of createFromJson

/// ...
    if(response.statusCode == 200) {
      List json = convert.jsonDecode(response.body);
      return BsSelectBoxResponse.createFromJson(json, 
        value: (data) => data['typecd'],
      );
    }
/// ...

• If you want to make typecd as text of option, use renderText parameters of createFromJson
• renderText function need returned Widget

/// ...
    if(response.statusCode == 200) {
      List json = convert.jsonDecode(response.body);
      return BsSelectBoxResponse.createFromJson(json, 
        value: (data) => data['typecd'],
        renderText: (data) => Text(data['typecd'])
      );
    }
/// ...
