Stack class

The Stack widget has limited hit test when child is overflow with Positioned. This behavior is intentional. For more detail refer to the bug report: Document that widgets in the overflow of stack do not respond to gestures.

The optional way to enable the hit test is define a new Stack and remove the size checking when the Stack instance is overflow enable.

Methods

blurred({double blur = 5, Color blurColor = Colors.white, BorderRadius? borderRadius, double colorOpacity = 0.5, Widget? overlay, AlignmentGeometry alignment = Alignment.center}) → Blur

Available on Widget, provided by the BlurExtension extension

createElement() → MultiChildRenderObjectElement

RenderObjectWidgets always inflate to a RenderObjectElement subclass.

inherited

createRenderObject(BuildContext context) → RenderStack

Creates an instance of the RenderObject class that this RenderObjectWidget represents, using the configuration described by this RenderObjectWidget.

override

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

didUnmountRenderObject(covariant RenderObject renderObject) → void

This method is called when a RenderObject that was previously associated with this widget is removed from the render tree. The provided RenderObject will be of the same type as the one created by this widget's createRenderObject method.

inherited

frosted({double blur = 5, Color frostColor = Colors.white, AlignmentGeometry alignment = Alignment.center, double? height, double? width, double frostOpacity = 0.0, BorderRadius? borderRadius, EdgeInsetsGeometry padding = EdgeInsets.zero}) → Blur

Available on Widget, provided by the FrostExtension extension

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.

inherited

updateRenderObject(BuildContext context, covariant RenderStack renderObject) → void

Copies the configuration described by this RenderObjectWidget to the given RenderObject, which will be of the same type as returned by this object's createRenderObject.
