Example causes CPU to go to max

See original GitHub issue

Issue Description

Hey y’all. Really appreciate these libraries!

I’ve been trying to get the example to work but unfortunately when I run it it causes the CPU to go to 200% in the simulator. To try to isolate the issue I’ve created a brand new expo project and copied the example, but it still causes the CPU to spike after swiping the first item.

I’ve included the project.json and a video showing the behavior below.

Any guidance on how to understand what’s happening here? Thanks

I can confirm it is working on 2.0.6! But I have the same issue with 2.0.7

The issue seems to be caused by this function:

if (open) { [...itemRefs.current.entries()].forEach(([id, ref]) => { if (id !== && ref) ref.close(); });

@jmif If you can provide a repro via an expo snack I’ll take a look.
