💪 this is not connected to this topic . I made a custom widget. now in the home screen I used it. The custom widget is made of a container. is there a way for me to change the properties of the container from the home screen?

Hey, I want to make a piano/xylophone app/game... How can I change the button (or any widget) so that I can glide/slide my finger and play the key, not waiting for the release of touch? Everything else is done. Thanks

[@skondgekar]

I think you can use gesture detector.

With newer Flutter sdk version you get the error:
AnimationController _animationController; --> Non-nullable instance field '_animationController' must be initialized.

[@nickmead8146]

You can declare the controller as type AnimationController? just make sure you assert that its not null when you use it with _animationController!

Galaxy was rotating in wrong direction.🧐

[@ValdaXD]

You can reverse the animation. Or the animation playback.
Heck you can even merge animationControllers .

[@Jango114]

and nearest stars to the center should rotate faster too...
