Dynamic and responsive ListView in flutter

How to create responsive and dynamic Listview?

Step 1:

Create Listview builder

ListView.builder(
    physics: ScrollPhysics(parent: AlwaysScrollableScrollPhysics()),
    itemCount: allBillList[0].data!.length,
    scrollDirection: Axis.vertical,
    itemBuilder: (c, index1) {
      String data = mainList![index1];
      return ListItem(data);

})

Step 2:

Create separate ListItem.dart file

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

class ListItem extends StatefulWidget {
  ListItem({this.data});

  final String? data;

  @override
  _ListItemState createState() => _ListItemState();
}

class _ListItemState extends State<ListItem> {
  

  @override
  Widget build(BuildContext context) {
    // TODO: implement build

    return Column(
      children: [
        Container(margin: const EdgeInsets.all(16.0), child:Text(data)),
        BasicWidget.getDivider(),
      ],
    );
  }
  

}

So if you want to delete or add items in mainList just add setState outside delete and insert functionality
just like,

 setState(() {
    mainList =mainList.add("test");
  });
}
this will automatically refresh your listview.
