I'm getting an error when I want to export a default realm configuration useRealm so that I will be able to use it other files
import Realm from "realm";
import { getRealmApp } from "../functions/realmConfig";
import { ItemSchema } from "./itemSchema";
export const app = getRealmApp();
export const useRealmApp = getRealmApp();
export const user = useRealmApp.currentUser;
export const partitionValue = useRealmApp.currentUser.id;
export const config = {
schema: [ItemSchema], //other schema will be added in the future
sync: {
user: user,
partitionValue: partitionValue, //app.currentUser.id,
},
};
export const useRealm = new Realm(config);
expected results is, if the user is not logged in it should show a login screen. But it throws this error and doesn't give me a chance to log in:
index.ts?77fd:9 Uncaught TypeError: Cannot read property 'id' of null
at eval (index.ts?77fd:9)

probably use (add question marks)
useRealmApp?.currentUser?.id
Because if you are not logged in, useRealmApp.currentUser is undefined/null, hence you cannot read .id.
Though, it doesn't seems to be the right way to work with react native, you should probably create a store (redux/useContext), then monitor your user login/logout, and update your user/partition states.
Try this, but not sure if it will work
const user: any = Realm.User;
export const useRealm = Realm.open({
schema: [ItemSchema],
sync: {
user: user.prototype,
partitionValue: app.currentUser?.id!,
error: (e) => {
console.log(e);
},
},
});
