SlideTransition class

Animates the position of a widget relative to its normal position.

The translation is expressed as an Offset scaled to the child's size. For example, an Offset with a dx of 0.25 will result in a horizontal translation of one quarter the width of the child.

By default, the offsets are applied in the coordinate system of the canvas (so positive x offsets move the child towards the right). If a textDirection is provided, then the offsets are applied in the reading direction, so in right-to-left text, positive x offsets move towards the left, and in left-to-right text, positive x offsets move towards the right.

Here's an illustration of the SlideTransition widget, with its position animated by a CurvedAnimation set to Curves.elasticIn:

The following code implements the SlideTransition as seen in the video above:

Methods

build(BuildContext context) Widget
Override this method to build widgets that depend on the state of the listenable (e.g., the current value of the animation).
override
createElement() StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() State<AnimatedWidget>
Subclasses typically do not override this method.
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}) 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.
