はじめまして。ValueTreeを使用したTimelineを開発したいのですが、良いサンプルやチュートリアルはありますでしょうか?

hey, don’t wanna be rude or anything, but you are more likely to get support in english

@Mrugalla Thank you for you advise.

I would like to develop a timeline with ValueTree. Are There tutorials or a samples about that ?

a timeline, like this?

https://www.google.com/search?q=timeline&client=ms-android-oneplus&prmd=imvxn&sxsrf=AOaemvIfK2nnpVdv31Fnq3bP1BqS9eNLhA:1632645410279&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiqw-SNnpzzAhX7hv0HHXPfCSgQ_AUoAXoECAIQAQ&biw=360&bih=560&dpr=3#imgrc=y7cLbxoGA0_YkM

in ValueTree i’d think this would just be a bunch of children for each point in time with its time value, and each of these children would have a property for the text description

I am assume the timeline like this.
