If you are interested in draw_your_image, just pub add it to your sample project and ask your AI agent to build a fancy drawing page. Providing AI_GUIDE.md, published on the GitHub repo, to AI will help it generate more accurate source code. #FlutterDev github.com/chooyan-eng/...

Tbh, I don't think draw_your_image is "handy"; you have to manage strokes state by yourself or implement clear/undo/redo by yourself by writing more lines of code than other packages. However, you can flexibly build any behavior and UX integrating with your app. #FlutterDev

3. Cusomizable: For advanced usage, most of the behaviors or algorithms, such as input device-based behavior, smoothing, or intersection detection, can be customized. The "best" logic should be different for each app, I believe, so make and apply yours if necessary. #FlutterDev

Tsuyoshi Chujo @chooyan.bsky.social · 02/02/2026

2. All the data is on your side: Because Draw behaves just as a "renderer" of the given strokes, it never preserves them internally. This approach is useful when you want to modify, save, or clear the data depending on your requirements. #FlutterDev

1. Decralative: draw_your_image is “controller”-free; you don't need to create, attach, or dispose of any controller. Like the Slider widget, all the user interactions and created data are notified via callback, and they are rendered by giving it back as "strokes". #FlutterDev

I’ve recently published multiple updates of my drawing package, draw_your_image. I’ve put lots of my ideas to differentiate it from other similar packages, and now it must be a good alternative for more advanced use cases. In this thread, let me explain why!🧵 #FlutterDev

As it's almost stable, I won't change the API a lot anymore, so just feel free to try it out 👍

Tsuyoshi Chujo @chooyan.bsky.social · 14/07/2025

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

Making sliver version of AnimatedTo would be my next challenge. I’m sure it will be tough…!

Tsuyoshi Chujo @chooyan.bsky.social · 20/03/2025

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

Thanks! What AnimateTo widget does is overriding paint() method of its RenderObject so that it cancels the default behavior and continuously calls paintChild() using AnimationController. It doesn’t require any additional widget to display animation, but the target widget itself is animating.

Tsuyoshi Chujo @chooyan.bsky.social · 18/12/2024

Actually, my original challenge was to make that kind of UI in my app. This package was made after breaking down what I must do. I hope this will help your development!
