SlideTransition class Null safety

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:

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.

debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
protected">@protectedinherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
