Reload Page and Filter data After selecting item in DropDownButton in Flutter?

Question

I have a page that displays all products from a rest Api. On the same page I have a DropDownButton which is populated with the various categories. My question is how can I filter the data after selecting an item from the dropdown button and also reload the page with the filtered data?

Was able to work it out like this for anyone who it may help.

InkWell(
                                      onTap: () {
                                        clearimage();
                                      },
                                      child: Row(
                                        children: <Widget>[
                                          Icon(
                                            Icons.cancel,
                                            color: red,
                                            size: 13.0,
                                          ),
                                          Padding(
                                            padding: const EdgeInsets.only(
                                                left: 15.0),
                                            child: Text(
                                              "Remove",
                                              style: TextStyle(fontSize: 10),
                                            ),
                                          ),
                                        ],
                                      ),
                                    ),

i called a method clearimage(); i had to File _mage back to null

  clearimage() {
    setState(() {
      _image = null;
    });
  }
