returnUnifiedContacts property
Return unified contacts instead of raw contacts.
On both iOS and Android there is a concept of raw and unified contacts. A single person might have two raw contacts (for example from Gmail and from iCloud) but will be merged into a single view called a unified contact. In a contact app you typically want unified contacts, so this is what's returned by default. When this is false, raw contacts are returned instead.
Implementation
bool returnUnifiedContacts = true;
