draw_your_image | Flutter package A Flutter package which enables users to draw with fingers in your designed UI.

Thank you for using draw_your_image, and feel free to send me any feedback! #FlutterDev pub.dev/packages/dra...

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

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

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

Yeah, see you there!

My talk is now introduced on #ftcon25eu website! My topic is, of course, my animated_to package! And also I'll cover how RenderObject works under our widgets. #FlutterDev www.fluttercon.dev/speakers/tsu...

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

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

I've published another article about the "explicit" animations of Flutter! Open the link below if you are interested in physics-based animation as well as the basics of AnimationController without using any packages! chooyan.hashnode.dev/all-i-know-a... #FlutterDev

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

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

I've published my resume page using Flutter web on GitHub Pages! Flutter web enables me to embed the demo section for my #FlutterDev packages. Visit there and try them. Also, feel free to contact me if I have chance to join any projects as a freelancer. chooyan-eng.github.io/chooyan_resu...

@i.madethese.works By the way, how do you make your GIF file on your heroine’s readme? I’m wondering how I can make such a smoothly animating GIF files.

Thanks so much! I’ll check the issue.

All I Know about Something - Chooyan's Flutter This series shows my understanding of a certain topic. The articles describe the topic as much as topics in a random order.

During the New Year holidays, I've published multiple articles to my "All I Know about Something" series on @hashnode.bsky.social. The knowledge about BuildContext, GlobalKey, and Layout calculation will make your #FlutterDev more enjoyable in 2025! chooyan.hashnode.dev/series/all-i...

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.

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!

Thanks! and I’ve published another one. 💪
