It looks like you might have been able to bypass this in your app, but if not, how did you approach that aspect of it?
I do very much like Redux, but definitely that whole data flow layer can be intimidating. Wes Bos has a great free course on react / redux ( https://learnredux.com/ ) that can help that learning process, and there is the excellent courses on https://reacttraining.com/ if you are willing to invest a little bit of money on learning.
With all that said, you don't _need_ to use Redux or anything else to work with storing data. It might be a good idea to try manually storing with the aforementioned storage library just so you can get something working and feel like you're making progress; and then spending some time with Redux and (https://github.com/michaelcontento/redux-storage provides support for storing data with react native). Good luck!
The simplest option is just to read and write a blob of JSON using the AsyncStorage API: https://facebook.github.io/react-native/docs/asyncstorage.ht...
Another option you could try is Realm, which is commercial but has a free tier (even for commercial apps) and has a pretty simple API: https://news.realm.io/news/introducing-realm-react-native/
Another is the SQLite module which comes with Expo:
Docs: https://docs.expo.io/versions/v16.0.0/sdk/sqlite.html Example: https://github.com/expo/sqlite-example/blob/master/main.js
Even using React Native is more than I'd normally do, but I don't see a better cross-platform option right now.
It'd be really nice if I get away without Redux. It was the main pain point I had with it, everything else was fairly smooth.
