Methods
-
createBoxPainter(
[VoidCallback? onChanged]) → _TriangleDecorationPainter -
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.
override
-
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.
override
-
lerpFrom(
Decoration? a, double t) → TriangleIndicator? -
Linearly interpolates from another Decoration (which may be of a
different class) to
this.override -
lerpTo(
Decoration? b, double t) → TriangleIndicator? -
Linearly interpolates from
thisto another Decoration (which may be of a different class).override -
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.
inherited
Operators
-
operator ==(
dynamic other) → bool -
The equality operator.
override
Static Methods
-
lerp(
TriangleIndicator? a, TriangleIndicator? b, double t) → TriangleIndicator? -
Linearly interpolates between two Decorations.
