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)); });
