Properties
- alignment → IndicatorAlignment?
-
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- height → double
-
final
- image → Image
-
final
- 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.

- relativeOffsetX → double?

final
- relativeOffsetY → double?

final
- runtimeType → Type
-
A representation of the runtime type of the object.

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.

different class) to
this.inherited -

toStringShort(
) → String -

hashCode.
