FlDotCirclePainter class
This class is an implementation of a FlDotPainter that draws a circled shape
- Inheritance
-
- Object
- FlDotPainter
- FlDotCirclePainter
Constructors
- FlDotCirclePainter({Color color = Colors.green, double? radius, Color strokeColor = const Color.fromRGBO(76, 175, 80, 1), double strokeWidth = 0.0})
-
The color of the circle is determined determined by
color
,radius
determines the radius of the circle. You can have a stroke line around the circle, by setting the thickness withstrokeWidth
, and you can change the color of of the stroke withstrokeColor
.
Properties
- color ↔ Color
-
The fill color to use for the circle
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- mainColor → Color
-
Used to show default UIs, for example defaultScatterTooltipItem
no setteroverride
-
props
→ List<
Object?> -
Used for equality check, see
EquatableMixin
.no setter - radius ↔ double
-
Customizes the radius of the circle
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- stringify → bool?
-
If set to
true
, the toString method will be overridden to output this instance's props.no setterinherited - strokeColor ↔ Color
-
The stroke color to use for the circle
getter/setter pair
- strokeWidth ↔ double
-
The stroke width to use for the circle
getter/setter pair
Methods
-
draw(
Canvas canvas, FlSpot spot, Offset offsetInCanvas) → void -
Implementation of the parent class to draw the circle
override
-
getSize(
FlSpot spot) → Size -
Implementation of the parent class to get the size of the circle
override
-
hitTest(
FlSpot spot, Offset touched, Offset center, double extraThreshold) → bool -
Used to implement touch behaviour of this dot, for example,
it behaves like a square of getSize
Check FlDotCirclePainter.hitTest for an example of an implementation
override
-
lerp(
FlDotPainter a, FlDotPainter b, double t) → FlDotPainter -
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
