AnimatedWidgetBuilder<T> typedef

AnimatedWidgetBuilder<T> = Widget Function(BuildContext context, Widget? child, T value)

Builder function used by widgets to update your scene when animating.

It has the pattern context, child and value.

context is your Flutter BuildContext.

child is any widget that is not effected by the animation. Flutter doesn't need to rebuild that widget when the animation updates. This way you can improve the performance of your animation.

value is current value of your animated property.

Implementation

typedef AnimatedWidgetBuilder<T> = Widget Function(
    BuildContext context, Widget? child, T value);
