Error: Realm at path ‘/data/user/0/com.drug/files/drugApp.realm’ already opened on current thread with different schema.
To solve this error you need to close Realm instance like below code example:-
export const insertNewContact = newcontact => new Promise((resolve,reject) => {
Realm.open(databaseOptions).then(realm=>{
realm.write(() => {
console.log(newcontact);
realm.create(CONTACT_SCHEMA, newcontact);
resolve(newcontact);
realm.close();
});
}).catch((error) => reject(error));
});
