MagnifierDecoration class

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).

Properties

color → Color?
The color to fill in the background of the shape.
finalinherited
gradient → Gradient?
A gradient to use when filling the shape.
finalinherited
hashCode → int
The hash code for this object.
read-onlyoverride
image → DecorationImage?
An image to paint inside the shape (clipped to its outline).
finalinherited
isComplex → bool
Whether this decoration is complex enough to benefit from caching its painting.
read-onlyinherited
opacity → double
The magnifier's opacity.
final
padding → EdgeInsetsGeometry
The inset space occupied by the shape's border.
read-onlyinherited
runtimeType → Type
A representation of the runtime type of the object.
read-onlyinherited
shadows → List<BoxShadow>?
A list of shadows cast by the shape.
finalinherited
shape → ShapeBorder

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