How to add Border Radius/Make Circular Image in Flutter
Introduction
In mobile app development, visuals play a crucial role in enhancing user experience. Flutter, being a popular framework for building cross-platform applications, provides various ways to customize the appearance of widgets. One such customization is adding a border radius to images or making them circular. In this article, we will explore how to achieve this in Flutter.
Understanding Border Radius
Border radius is a property that allows you to add rounded corners to widgets, including images. This can be particularly useful when you want to display profile pictures or thumbnails with a rounded appearance.
Adding Border Radius to Images
To add a border radius to an image in Flutter, you can use the `ClipRRect` widget or the `Container` widget with the `decoration` property. Here’s an example of how to use `ClipRRect`:
“`dart
ClipRRect(
borderRadius: BorderRadius.circular(10.0),
child: Image.asset(‘image_path’),
)
“`
Alternatively, you can use the `Container` widget:
“`dart
Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10.0),
image: DecorationImage(
image: AssetImage(‘image_path’),
fit: BoxFit.cover,
),
),
)
“`
Making Circular Images
To make a circular image, you can use the `CircleAvatar` widget or the `ClipOval` widget. Here’s an example of how to use `CircleAvatar`:
“`dart
CircleAvatar(
backgroundImage: AssetImage(‘image_path’),
radius: 50.0,
)
“`
Alternatively, you can use the `ClipOval` widget:
“`dart
ClipOval(
child: Image.asset(‘image_path’),
)
“`
Customizing the Appearance
You can further customize the appearance of your images by adding a border, shadow, or overlay. For example, you can add a border to your circular image using the `CircleAvatar` widget’s `backgroundColor` and `foregroundColor` properties.
“`dart
CircleAvatar(
backgroundImage: AssetImage(‘image_path’),
radius: 50.0,
backgroundColor: Colors.white,
foregroundColor: Colors.black,
)
“`
