how to handle multiple dynamic checkbox in datatable in flutter?

i'm building an app in which data like docket number, booking date, etc. coming from the api in the data table. so how can i handle the dynamic checkbox here and by clicking on the checkbox that row got selected and after that i want to post that row or multiple row data to the api.

class _ChallanEntry13State extends State<ChallanEntry1> {
  TextEditingController _number = new TextEditingController();
  TextEditingController _message = new TextEditingController();
  Map<String, dynamic> _categories = {
    "responseCode": "1",
    "responseText": "List categories.",
    "responseBody": [
      {"category_id": "5"},
    ],
  };
  void _onCategorySelected(bool selected, category_id) {
    if (selected == true) {
      setState(() {
        _selecteCategorys.add(category_id);
      });
    } else {
      setState(() {
        _selecteCategorys.remove(category_id);
      });
    }
  }
  var finaldate;
  var finaldate1;
  var responseResult;
  bool enable=false;
  List _selecteCategorys = List();
