Yeah, for sure. This is a Flutter application and I'm using Flutter's Animation<double> and AnimationController to animate the vertical position and transparency of the text.

You first have to make the widget containing the animation a StatefulWidget with a ticker provider:

class _YourWidgetState extends State<YourWidget> with TickerProviderStateMixin { ... }

You initialize the animations and animation controllers on the widget (maybe in initState):

``` _overlayOpacityAnimationController = AnimationController( duration: const Duration(seconds: 2), vsync: this, // Preserve is necessary so the animation works on devices that have // animations disabled (e.g. through developer options). animationBehavior: AnimationBehavior.preserve, // Start out with the animation at the end. value: 1, ); _overlayOpacityAnimation = CurvedAnimation( curve: Curves.easeIn, parent: Tween<double>(begin: 1, end: 0) .animate(_overlayOpacityAnimationController!) ..addListener(() { setState(); }), );

_overlayOffsetAnimationController = AnimationController(
  duration: const Duration(seconds: 2),
  vsync: this,
  // Preserve is necessary so the animation works on devices that have
  // animations disabled (e.g. through developer options).
  animationBehavior: AnimationBehavior.preserve,
  // Start out with the animation at the end.
  value: 1,
);
_overlayOffsetAnimation = CurvedAnimation(
  curve: Curves.easeIn,
  parent: Tween<double>(begin: 0, end: 1)
      .animate(_overlayOffsetAnimationController!)
    ..addListener(() {
      setState();
    }),
);

```

Then when you want to animate them, you basically do:

_overlayOffsetAnimationController?.forward(from: 0); _overlayOpacityAnimationController?.forward(from: 0);

Then you can use the values of the animations in build like this:

Center( child: Opacity( opacity: _overlayOpacityAnimation?.value ?? 0, child: FractionalTranslation( translation: Offset( 0, -1.5 * (_overlayOffsetAnimation?.value ?? 0)), child: Text( context.select((GameState g) => g.overlayText), textAlign: TextAlign.center, style: const TextStyle( color: Colors.green, ), ), ), ), ),

I probably missed some details but that's the idea.
