How to Add Divider Between Each Line with Different Methods in Flutter

1. ListTile.divideTiles : You can use it with a short static list.

ListView(
  children: ListTile.divideTiles( //divideTiles!!         
      context: context,
      tiles: [
        ListTile(
          title: Text('One'),
        ),
        ListTile(
          title: Text('Two'),
        ),
        ListTile(
          title: Text('Three'),
        ),
      ]
  ).toList(),
)

2.ListView.separated : You can use it with a long dynamic list.

ListView.separated(
  itemCount: 200,
  itemBuilder: (context, index) {
    return ListTile(
      title: Text('$index number'),
    );
  },
  separatorBuilder: (context, index) {
    return Divider();
  },
)

3. You can use this for adding a divider after each item:

With using Divider() :

final items = ['One', 'Two', 'Three', 'Four', 'Five'];

@override
Widget build(BuildContext context) {
  return ListView.builder(
    itemCount: items.length,
    itemBuilder: (context, index) {
      return Column(
        children: <Widget>[
          ListTile(
            title: Text(items[index]),
          ),
          Divider(), // Divider
        ],
      );
    },
  );
}

With using BoxDecoration:

final items = ['One', 'Two', 'Three', 'Four', 'Five']; 
@override
Widget build(BuildContext context) {
  return ListView.builder(
    itemCount: items.length,
    itemBuilder: (context, index) {
      return Container(
        decoration: BoxDecoration(   //BoxDecoration
          border: Border(bottom: BorderSide(  //Add border as a divider
             height:2.0,color:Colors.grey)), 
        ),
        child: ListTile(
          title: Text(items[index]),
        ),
      );
    },
  );
}

You can also use Divider() with Card widget too:

final items = ['One', 'Two', 'Three', 'Four', 'Five'];

@override
Widget build(BuildContext context) {
  return ListView.builder(
    itemCount: items.length,
    itemBuilder: (context, index) {
      return Card(      //Card
        child: ListTile(
          title: Text(items[index]),
        ),
      );
    },
  );
}
