Pinned class

Pinned attempts to fill as much space as is available, and position its child within that space based on specified edge positions. It mirrors the Adobe XD responsive layout model, but can be used independently. Please see the README for additional information and examples.

Constructors

Pinned({Key? key, double? left, double? leftFraction, double? right, double? rightFraction, double? width, double? horizontalMiddle, double? top, double? topFraction, double? bottom, double? bottomFraction, double? height, double? verticalMiddle, required Widget child})
Constructs a Pinned instance by building horizontal & vertical Pin instances from semantic parameters. For example, providing left & width parameters would result in a hPin having start and size values.
Pinned.fromPins(Pin hPin, Pin vPin, {required Widget child, Key? key})
Positions and sizes a single child based on settings defined in horizontal and vertical Pin instances. See the Pin documentation for details.
Pinned.fromSize({Key? key, required Rect bounds, required Size size, bool pinLeft = false, bool pinRight = false, bool pinTop = false, bool pinBottom = false, bool fixedWidth = false, bool fixedHeight = false, required Widget child})
Constructs a Pinned instance based on parameters that reflect the layout UI in Adobe XD:

Methods

createElement() → SingleChildRenderObjectElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
createRenderObject(BuildContext context) → RenderShiftedBox
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
A render object previously associated with this widget has been removed from the tree. The given RenderObject will be of the same type as returned by this object's createRenderObject.
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.
override
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → 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 RenderPinned 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.
override

Operators

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