MagnifierDecoration class Null safety

A decoration for a RawMagnifier.

MagnifierDecoration does not expose ShapeDecoration.color, ShapeDecoration.image, or ShapeDecoration.gradient, since they will be covered by the RawMagnifier's lens.

Also takes an opacity (see https://github.com/flutter/engine/pull/34435).

padding EdgeInsetsGeometry
The inset space occupied by the shape's border.
read-onlyinherited
runtimeType Type

Methods

createBoxPainter([VoidCallback? onChanged]) BoxPainter
Returns a BoxPainter that will paint this decoration.
inherited
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) ShapeDecoration?
Linearly interpolates from another Decoration (which may be of a different class) to this.
inherited
lerpTo(Decoration? b, double t) ShapeDecoration?
Linearly interpolates from this to another Decoration (which may be of a different class).
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent 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.
