Strikethrough Animation

Hi, I'm Yashas this will be my first contribution.

I had a pretty cool idea when I was working on a todo app, I wanted to mark the task as done and strikethrough the text but there was no option to do so with an animation. I looked through various libraries but wasn't able to find a good one.

I have been using animated text kit for some time a now and thought of contributing to the library by adding a strike through animation.

Is anyone working on this? If not, may I contribute to this?

Look at existing animations in the lib/ directory to understand the pattern. The new strikethrough animation will need to extend or follow the same structure. Check how text styling and animations are combined in the package. Test the new animation in the example app to ensure it works as expected.
