I found an open issue on the react-native github which seems
related https://github.com/facebook/react-native/issues/31523
but after following all of their suggestions I still have the
same error. I tried:
- Removing @babel/plugin-proposal-class-properties & @babel/plugin-transform-flow-strip-types
- Adding @babel/plugin-transform-flow-strip-types
I tried out a bunch of formulas as well as
having them as options, and I ended up liking
the Brzycki formula the most.
https://en.wikipedia.org/wiki/One-repetition_maximum#Brzycki
All of them produced similar trends (for me) and the one using
exponents wouldn't work with the SQLite version on android
(can't use POWER function). Also having all the options looked
kind of cluttered. If people ask for it I'll add the other ones
later.
