ContinuousRectangleBorder creates a rectangular border with smooth continuous transitions between the straight sides and the rounded corners.

- RoundedRectangleBorder
- ShapeBorder
- StadiumBorder
- UnderlineInputBorder
ContinuousRectangleBorder constructor
const ContinuousRectangleBorder(
{BorderSide side: BorderSide.none,
BorderRadiusGeometry borderRadius: BorderRadius.zero}
)
Basically, ContinuousRectangleBorder's usage is the same as RoundedRectangleBorder. They all create a rectangular border with rounded corners. However, the rounded corners created by ContinuousRectangleBorder are smoother.
For example: Use ContinuousRectangleBorder for a Container:
(ex1)
Container(
width: 300,
height: 150,
decoration: ShapeDecoration(
color: Colors.white,
shape: ContinuousRectangleBorder (
borderRadius: BorderRadius.circular(32.0),
side: BorderSide(
width: 10,
color: Colors.blue
)
)
),
child: Center(
child: Text(
"Flutter",
style: TextStyle(fontSize: 50)
)
),
)
Use addition operator (+) to add 2 ShapeBorder in order to create an associative border:
(ex2)
Container(
width: 300,
height: 150,
decoration: ShapeDecoration(
color: Colors.white,
shape: ContinuousRectangleBorder (
borderRadius: BorderRadius.circular(16.0),
side: BorderSide(
width: 10,
color: Colors.blue
)
) + ContinuousRectangleBorder (
borderRadius: BorderRadius.circular(32.0),
side: BorderSide(
width: 20,
color: Colors.green
)
)
),
child: Center(
child: Text(
"Flutter",
style: TextStyle(fontSize: 50)
)
),
)
side - Provides parameters related to border such as color, width, style.
BorderSide side: BorderSide.none
BorderSide constructor
const BorderSide (
{Color color: const Color(0xFF000000),
double width: 1.0,
BorderStyle style: BorderStyle.solid}
)

Note: ContinuousRectangleBorder.side property does not work with ElevatedButton, TextButton and OutlinedButton. It is overridden by ButtonStyle.side.
borderRadius - Provides 4 corner radius value of the rectangle.
BorderRadiusGeometry borderRadius: BorderRadius.zero

decoration: ShapeDecoration(
color: Colors.white,
shape: ContinuousRectangleBorder (
borderRadius: BorderRadius.only(
bottomLeft: Radius.zero,
topLeft: Radius.zero,
bottomRight: Radius.circular(20),
topRight: Radius.circular(45)
),
side: BorderSide(
width: 10,
color: Colors.blue
)
)
),
child: Center(
child: Text(
