FallbackGlassSurface class

Last-resort glass: a plain blur with a tint and a hairline rim.

Used on Skia and web, where backdrop shaders are unavailable, and whenever the shader fails to compile.

Inheritance

Constructors

FallbackGlassSurface({required Glass glass, required GlassShape shape, required Widget child, double intensity = 1.0, double blurSigma = 18, Key? key}): Creates a blur-and-tint surface. blurSigma defaults higher than the shader path's: without refraction the edge does no work, so the material has to separate from the backdrop by blur alone.
const

blurSigma → double: Gaussian sigma, in logical pixels.
final
child → Widget: Content composited above the material.
final
glass → Glass: The material. Glass.identity renders child untouched; GlassVariant.clear drops the fill's opacity to roughly half of regular's.
final
hashCode → int: The hash code for this object.
no setterinherited
intensity → double: System glass intensity, 0–1. Scales both the blur and the tint.
final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
shape → GlassShape: Outline the surface is clipped to.
final

build(BuildContext context) → Widget: Describes the part of the user interface represented by this widget.
override
createElement() → StatelessElement: Creates a StatelessElement to manage this widget's location in the tree.
inherited
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
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
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.
