TriangleDecoration class
Decoration that can be used to render a triangle in the bottom-right corner of a container

Constructors
- TriangleDecoration({required Color color, required double size})
- Constructor
Properties
- color → Color
-
Color of the triangle
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- isComplex → bool
-
Whether this decoration is complex enough to benefit from caching its painting.
no setterinherited
- padding → EdgeInsetsGeometry
-
Returns the insets to apply when using this decoration on a box
that has contents, so that the contents do not overlap the edges
of the decoration. For example, if the decoration draws a frame
around its edge, the padding would return the distance by which
to inset the children so as to not overlap the frame.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- size → double
-
Width and height of the triangle
final
Methods
-
createBoxPainter(
[VoidCallback? onChanged]) → BoxPainter -
Returns a BoxPainter that will paint this decoration.
override
-
debugAssertIsValid(
) → bool -
In debug mode, throws an exception if the object is not in a
valid configuration. Otherwise, returns true.
inherited
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
inherited
-
getClipPath(
Rect rect, TextDirection textDirection) → Path -
Returns a closed Path that describes the outer edge of this decoration.
inherited
-
hitTest(
Size size, Offset position, {TextDirection? textDirection}) → bool -
Tests whether the given point, on a rectangle of a given size,
would be considered to hit the decoration or not. For example,
if the decoration only draws a circle, this function might
return true if the point was inside the circle and false
otherwise.
inherited
-
lerpFrom(
Decoration? a, double t) → Decoration? -
Linearly interpolates from another Decoration (which may be of a
different class) to
this.inherited -
lerpTo(
Decoration? b, double t) → Decoration? -
Linearly interpolates from
thisto another Decoration (which may be of a different class).inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString(
{DiagnosticLevel minLevel = DiagnosticLevel.info}) → String -
A string representation of this object.
inherited
-
toStringShort(
) → String -
A brief description of this object, usually just the runtimeType and the
hashCode.

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