Circle class

Defines a mathematical circle strictly via a radius.

Implemented types

Constructors

Circle({required double radius, Point<num>? center})
Creates a Circle with the given radius and center.

Properties

area → double
The total surface area of the shape.
no setteroverride
boundingBox → Rectangle
The smallest axis-aligned rectangle that completely encloses the shape.
no setteroverride
center → Point<num>
The center point of the circle in 2D space.
no setter
centroid → Point<double>
The mathematical center of mass of the shape.
no setteroverride
hashCode → int
The hash code for this object.
no setterinherited
perimeter → double
The total length of the shape's boundary.
no setteroverride
radius → double
The radius of the circle.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
rotate(double angle, [Point<num>? origin]) → Circle
Rotates the shape by the given angle (in radians) around the origin. If origin is omitted, rotates around the shape's centroid.
override
scale(num factor) → Circle
Scales the shape uniformly by the given factor originating from centroid.
override
toString() → String
A string representation of this object.
override
translate(Point<num> offset) → Circle
Translates the shape by the given vector offset.
override

Operators

operator ==(Object other) → bool
The equality operator.
