react-native-svg crashing in release in TesterApp about repack

[jbinda]

Hey @zamotany and @oblador

We did some investigation with @lukewalczak and we've noticed that disabling hermes prevents app crash in production.

We also get report that it occurs in TesterApp based on V3 of Re.Pack and RN 0.68 🤔 - however weren't able to reproduce it.

Any ideas what can cause a conflict with enabling hermes ?

For me at least it works if I run #106 instead of main branch (also works after rebase).

After investigating the issue, the crash is caused by react-native-svg itself in release mode. Debug works just fine.
Adding missing proguard rule and marking react-native-svg as nohoist doesn't solve the issue.
What's more interesting is that with Metro, react-native-svg doesn't crash but also doesn't render anything.

react-native-svg throws the same error with RN 0.66 (tested on #106).

I observed exactly the same behaviour when I disabled hermes with react-native version 0.72. Curious to understand what is hermes' implication here 🤔
