Use a global list of clipboard listeners

[LinusU]

Summary

Before this change, if two components on the same page used the clipboard hook, one of them wouldn't properly re-render if the other one updated the clipboard content.

Test Plan

I'm working on a small example app that shows two components that uses the clipboard at the same time, and demonstrates that it now works.

Here is a snack that demonstrates the working behaviour:

What are the steps to reproduce (after prerequisites)?

@pvinis hmm, is the checklist up to date? I went to add my changes to the changelog but it seems like it's generated automatically?

[pvinis]

Indeed. we need to revisit that.

[LinusU]

Ahh, it comes from here:

https://github.com/react-native-community/.github/blob/master/.github/PULL_REQUEST_TEMPLATE.md

Hmm, maybe we can just override it by adding our own version 🤔

[LinusU]

I've added a snack to test this out here:
https://snack.expo.io/@linusu/hooks-pr-76

🎉

[pvinis]

for sure. today and tomorrow I'm not easily next to my laptop, I could check later, or if you do something we check it.

Did it here: #77

This PR should be ready for review now, I've tested it on my iPhone and on the Web. Should be super easy for anyone to test out the snack ☺️

[pvinis]

having the snack is awesome! maybe we can add this in the template as a suggestion? 🤔

[pvinis]

I also plan to add some tests so people can copy paste and use them too.

Hehe, already did it in #77 😉

I also plan to add some tests so people can copy paste and use them too.

Maybe we could have an official snack which uses all the hooks. Then people can just fork that one and add whatever is specific to their PR? 🤔

Since each PR gets deployed with a canary version it's super easy to use them in the snacks 🙌

[pvinis]

yuuuuuuuuuusssssss!!! awesome idea.

[LinusU]

ping @pvinis, can we merge this? ☺️

[pvinis]

uup, forgot that. No one reviewed, lemme give it a look.
