Is there any way to store values other than strings with AsyncStorage? I want to store simple boolean values for example.
Based on the AsyncStorage React-native docs, I'm afraid you can only store strings..
static setItem(key: string, value: string, callback?: ?(error: ?Error) > => void)
Sets value for key and calls callback on completion, along with an Error if there is any. Returns a Promise object.
You might want to try and have a look at third party packages. Maybe this one.
