When developing mobile applications using Flutter, a common requirement is to create a circular icon button similar to a FloatingActionButton. This guide will walk you through various methods to achieve this, leveraging different Flutter widgets and providing practical examples.
Using RawMaterialButton
The RawMaterialButton widget is a versatile option for creating a circular button. It allows for detailed customization, including shape, padding, and elevation. Here’s how you can implement it:
RawMaterialButton(
onPressed: () {},
elevation: 2.0,
fillColor: Colors.white,
constraints: BoxConstraints(minWidth: 0.0),
child: Icon(
Icons.pause,
size: 35.0,
),
padding: EdgeInsets.all(15.0),
shape: CircleBorder(),
)
This method is particularly useful if you need a button with a specific size or if you want to customize the appearance extensively.
Using ElevatedButton with Newer Customizations
The ElevatedButton is a more modern approach, especially after updates in the Flutter framework. It provides a cleaner API for styling and customization:
ElevatedButton(
onPressed: () {},
child: Icon(Icons.menu, color: Colors.white),
style: ElevatedButton.styleFrom(
shape: CircleBorder(),
padding: EdgeInsets.all(20),
backgroundColor: Colors.blue, // Button color
foregroundColor: Colors.red, // Splash color
),
)
This approach is ideal for developers who prefer using the latest Flutter widgets with built-in material design aesthetics.
Using InkWell for Touch Feedback
If you desire more control over the button’s touch feedback and appearance, consider using InkWell wrapped in ClipOval:
ClipOval(
child: Material(
color: Colors.blue, // Button color
child: InkWell(
splashColor: Colors.red, // Splash color
onTap: () {},
child: SizedBox(width: 56, height: 56, child: Icon(Icons.menu)),
),
),
)
This method provides a more traditional approach, offering flexibility for customizing the button’s interaction style.
Conclusion
Choosing the right method for creating a circle icon button in Flutter depends on your specific needs, such as the level of customization required and the desired user interaction. Each of the approaches discussed has its strengths, and you can select based on your project requirements.
