SignedSpacingFlex class

A widget that displays its children in a one-dimensional array.

The SignedSpacingFlex widget allows you to control the axis along which the children are placed (horizontal or vertical). This is referred to as the main axis. If you know the main axis in advance, then consider using a SignedSpacingRow (if it's horizontal) or SignedSpacingColumn (if it's vertical) instead, because that will be less verbose.

To cause a child to expand to fill the available space in the direction of this widget's main axis, wrap the child in an Expanded widget.

Constructors

SignedSpacingFlex({Key? key, required Axis direction, double spacing = 0.0, StackingOrder stackingOrder = StackingOrder.firstOnTop, MainAxisAlignment mainAxisAlignment = MainAxisAlignment.start, MainAxisSize mainAxisSize = MainAxisSize.max, CrossAxisAlignment crossAxisAlignment = CrossAxisAlignment.center, TextDirection? textDirection, VerticalDirection verticalDirection = VerticalDirection.down, TextBaseline? textBaseline, Clip clipBehavior = Clip.none, List<Widget> children = const []})
Creates a flex layout.

Properties

children → List<Widget>
The widgets below this widget in the tree.
finalinherited
clipBehavior → Clip
Defaults to Clip.none.
final
crossAxisAlignment → CrossAxisAlignment
How the children should be placed along the cross axis.
final
direction → Axis
The direction to use as the main axis.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
mainAxisAlignment → MainAxisAlignment
How the children should be placed along the main axis.
final
mainAxisSize → MainAxisSize
How much space should be occupied in the main axis.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
spacing → double
The space between the children.
final
stackingOrder → StackingOrder
How the children should overlap.
final
textBaseline → TextBaseline?
If aligning items according to their baseline, which baseline to use.
final
textDirection → TextDirection?
Determines the order to lay children out horizontally and how to interpret start and end in the horizontal direction.
final
verticalDirection → VerticalDirection
Determines the order to lay children out vertically and how to interpret start and end in the vertical direction.

Methods

createElement() → MultiChildRenderObjectElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
createRenderObject(BuildContext context) → RenderSignedSpacingFlex
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.
override
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
getEffectiveTextDirection(BuildContext context) → TextDirection?
The value to pass to RenderSignedSpacingFlex.textDirection.
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}) → 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 RenderSignedSpacingFlex 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.
