Flutter ListTile Leading Height
The ListTile
widget in Flutter allows you to create a row-based layout commonly used in lists, grids, and other types of data displays. The leading
property of the ListTile
widget is used to set the widget that appears before the title in the row.
To specify the height of the leading
widget in a ListTile
, you can wrap the widget with a Container
and set its height property. Here’s an example:
ListTile(
leading: Container(
height: 48, // Specify the desired height here
child: Icon(Icons.person),
),
title: Text('John Doe'),
subtitle: Text('johndoe@example.com'),
)
In this example, we have set the height of the Container
to 48 pixels. You can adjust this value based on your design requirements. The leading
widget, which is an Icon
in this case, will be constrained to the specified height.
Additionally, if you want to maintain the aspect ratio of the leading widget and automatically adjust its width based on the specified height, you can use the AspectRatio
widget. Here’s an example:
ListTile(
leading: AspectRatio(
aspectRatio: 1/1, // Set the desired aspect ratio here
child: Icon(Icons.person),
),
title: Text('John Doe'),
subtitle: Text('johndoe@example.com'),
)
In this example, we have set the aspect ratio to 1/1
, which means the width will be the same as the height. This can be particularly useful when using images as the leading widget.
Remember to import the necessary dependencies for the ListTile
, Container
, Icon
, and AspectRatio
widgets.
