What is Flutter Container Border Radius?
Flutter container border radius can be used to shape the Flutter container widget. By using the border radius, we can change the edge shapes of the Flutter container widget. We will first see what the default Flutter container border radius is then we will change the border radius using multiple ways.
Default Flutter Container Border Radius
To see the default border radius of container, we have to define a simple Flutter container.
For demonstration, we have give our container a height, width, color and a Flutter text widget. See the below code:
Container( width: 240, height: 60, color: Colors.blue, alignment: Alignment.center, child: Text( 'Flutter Container Default Border radius', style: TextStyle(color: Colors.white, fontSize: 15), ), )

Change Flutter Container Border Radius(Multiple Ways)
To change the border radius, we have to use the decoration constructor of the container class and pass it box decoration. Then by using the border radius constructor, we can easily change the shape of Flutter container.
We will be using multiple ways to customize the Flutter container border radius. See below:
- Border Radius Circular
- Border Radius Only
Border Radius Circular
Border radius circular is used when you want to give the same circular value to each edge of the Flutter container. See below code:
borderRadius: BorderRadius.circular(10)

You can see the custom border radius shape of Flutter container in the above image. If you still want to give a different value to one or many edges then use the copy with. See the below code:
borderRadius: BorderRadius.circular(10).copyWith(topRight: Radius.circular(0))

Border Radius Only
It is used when you want to give each edge a different value. See the below code:
borderRadius: BorderRadius.only( topLeft: Radius.circular(3), topRight: Radius.circular(30), bottomLeft: Radius.circular(10), bottomRight: Radius.circular(0))

borderRadius: BorderRadius.only( topLeft: Radius.circular(3), bottomLeft: Radius.circular(10), bottomRight: Radius.circular(0)),

You now have a proper implementing knowledge of how to use and customize Flutter container border radius with multiple ways. Don’t hesitate to hold back your words if you still have any questions related to the customization of Flutter container border radius. I would love to answer all.
