Re-evaluate the possibility to use private methods (and @babel/plugin-proposal-private-methods) in the codebase again

[NqCompiler]

Hi,

thank you for fixing this project!

How to reproduce this error:
Just use FlatList and this project with the recommended plugin @babel/plugin-proposal-private-methods.
Here are two issues from stackoverflow (FYI: I am not using Expo):

https://stackoverflow.com/questions/69922302/react-native-flatlist-undefined-is-not-an-object-evaluating-props-getitem

Is this a possible solution?

1. make all private functions public by removing the hashtag prefix in src/index.ts
2. remove @babel/plugin-proposal-private-methods

Ok, whatever, I just released v0.6.0-alpha.4 which gets rid of the private class features for now.

It turns out (facebook/react-native#36828 (comment)) adding @babel/plugin-transform-flow-strip-types allows to avoid problems with <FlatList> when using private methods. Perhaps, with this in mind we can use them again.
