I haven't posted anything to Bluesky for a while, but now let me ask who has tried my package animated_to. It's so simple that the widget named AnimatedTo lets any widgets animate when they update their position; simple but so powerful, isn't it? pub.dev/packages/ani... #FlutterDev

My animated_to package now introduces “spring simulation” version of AnimatedTo widget, AnimatedTo.spring()! This enables physics-based animation when child updates its position, which means so smooth and natural! Try this by importing the latest version of 0.3.1! pub.dev/packages/ani... #FlutterDev
