How to add border to ListTile in Flutter

You can add border to ListTile in Flutter by adding a shape to it. While providing the shape parameter, you can add various shapes such as RoundedRectangleBorder, StadiumBorder, and BeveledRectangleBorder.

To add border to ListTile in Flutter:

1. Locate the file where you have placed the ListTile widget.
2. Add the shape parameter and assign either RoundedRectangleBorder, StadiumBorder, or BeveledRectangleBorder.
3. For example, if you have added RoundedRectangleBorder, then, Inside the RoundedRectangleBorder widget, add the side property and assign the BorderSide(width: 2) widget.
4. Also, add the borderRadius property and assign the BorderRadius.circular(20).

Code Example

final List<String> items = List<String>.generate(10, (i) => '$i');
ListTile(
  shape: RoundedRectangleBorder( //<-- SEE HERE
    side: BorderSide(width: 2),
    borderRadius: BorderRadius.circular(20),
  ),
  leading: CircleAvatar(
    backgroundColor: const Color(0xff6ae792),
    child: Text(
      items[index],
      style: TextStyle(color: Colors.black),
    ),
  ),
  title: Text(
    'Item ${items[index]}',
  ),
  subtitle: Text('Item description'),
  trailing: Icon(Icons.more_vert),
);

Output

How to add ListTile border radius or rounded border

To add a border radius or create a rounded border around the ListTile, you can define the shape parameter with the RoundedRectangleBorder widget. Inside the RoundedRectangleBorder you can add side parameter with BorderSide(width: 2) and borderRadius with BorderRadius.circular(50). 

Code Example

ListTile(
  shape: RoundedRectangleBorder(
    side: BorderSide(width: 2),
    borderRadius: BorderRadius.circular(50), //<-- SEE HERE
  ),
...
);

Output

Changing ListTile border color

To add or change the ListTile border color, add the shape parameter with RoundedRectangleBorder() inside the ListTile widget. Inside the RoundedRectangleBorder widget, add the side property and assign the BorderSide(width: 2, color: Colors.amberAccent). Change the color parameter to the parameter of your choice.

Code Example

ListTile(
  shape: RoundedRectangleBorder(
    side: BorderSide(width: 2, color: Colors.amberAccent),
    borderRadius: BorderRadius.circular(10),
  ),
...
);

Output

Adding ListTile bottom or top border

To add ListTile bottom or top border, you can wrap the ListTile widget inside the Container and add the decoration. Inside the decoration parameter, add the Boxdecoration widget with border parameter and assign it to either Border(bottom: new BorderSide()) or Border(bottom: new BorderSide()).

NOTE: If you want to add something like a divider between the ListTile item, there is a better solution. Please check here.

Code Example

//Bottom
Container(
  decoration: BoxDecoration(border: Border(bottom: BorderSide())),
  child: ListTile(
    leading: CircleAvatar(
      backgroundColor: const Color(0xff6ae792),
      child: Text(
        items[index],
        style: TextStyle(color: Colors.black),
      ),
    ),
    ...
  ),
);
//Top
Container(
  decoration: BoxDecoration(border: Border(top: BorderSide())),
  child: ListTile(
    leading: CircleAvatar(
      backgroundColor: const Color(0xff6ae792),
      child: Text(
        items[index],
        style: TextStyle(color: Colors.black),
      ),
    ),
    ...
  ),
);

Output

Problem: This approach creates a blank border at the top or bottom side. To overcome this, you can add the divider between ListTile.

ListTile shape border

You can add different shape borders to the ListTile by adding shape widgets such as RoundedRectangleBorder, StadiumBorder, and BeveledRectangleBorderto the shape parameter inside the ListTile widget.

Code Example

ListTile(
  shape: BeveledRectangleBorder( //<-- SEE HERE
    side: BorderSide(width: 2),
    borderRadius: BorderRadius.circular(20),
  ),
  ...
);

Output

Adding divider between ListTiles

To add a divider between ListTiles, you can use the ListView.separated widget. Inside the ListView.separated, add the itemCount and itemBuilder as usual. And then, add the separatorBuilder that returns the Divider widget.

Code Example

ListView.separated( //<-- SEE HERE
  itemCount: items.length,
  itemBuilder: (context, index) {
    return ListTile(
      leading: CircleAvatar(
        backgroundColor: const Color(0xff6ae792),
        child: Text(
          items[index],
          style: TextStyle(color: Colors.black),
        ),
      ),
      title: Text(
        'Item ${items[index]}',
      ),
      subtitle: Text('Item description'),
      trailing: Icon(Icons.more_vert),
    );
  },
  separatorBuilder: (context, index) {//<-- SEE HERE
    return Divider(
      thickness: 2,
    );
  },
)

Output
