IndexedStack class final

Shows the child at index and keeps the rest mounted but unpainted, so their state survives switching between them — the basis for tabbed or paged surfaces that must remember each page. Sized to the largest child; an out-of-range index shows nothing.

Methods

animate({Duration? duration, Curve? curve, Object? trigger, bool repeat = false}) → Animate

Available on Widget, provided by the AnimateExtension extension

Starts an Animate chain over this widget. duration / curve apply to the whole chain. With no trigger it plays on mount; with a non-null trigger it rests on mount and replays whenever the token changes.
createElement() → MultiChildRenderObjectElement
Creates the Element that will mount this widget into the tree.
override
createRenderObject(BuildContext context) → RenderObject
Creates the render object backing this widget. Called once when the element first mounts.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
updateRenderObject(BuildContext context, covariant RenderIndexedStack renderObject) → void
Applies any changes from a new widget instance to the existing render object. Default is a no-op; subclasses override when the widget carries layout/paint configuration.
