Hi @grsoares21, thanks for the PR! This looks good to me except for a minor change.

[hshoff]

I see this is called from componentDidMount(). Ideally we could move this initial state to the constructor() because it doesn't rely on the DOM.

[grsoares21]

Sorry, it took me so long to fix this. I've moved the whole state initialization into the constructor with the id generation in there as well.

@grsoares21 I'm very sorry, Text has been refactored by hook(#946 ) that means you should rewrite this feature...... I‘m sincerely sorry about it........

Hello @susiwen8 . No problems :D. I'm glad to hear it's on hooks now. I'll try to reimplement this next weekend then.

Sorry for the delayed review, will try and review asap once I see any new commits to avoid any future conflicts 👍

[derrickbeining]

Came here for this very thing. Sad to see it has stalled. Are you planning to pick it up again @grsoares21 ?

[williaster]

If someone else wants to pick this up I'm happy to review! it shouldn't be too complicated, tho as noted @visx/text was refactored to use hooks so the approach will need to be tweaked slightly for that.
