app_contact_checker

Important Notes

• Platform-Specific Behavior:

  • On Android, the plugin checks if a specific phone number is actually registered with the corresponding app (e.g., WhatsApp, Telegram).
  • On iOS, due to privacy restrictions, the plugin only checks if the corresponding app is installed. It does not check for the presence of a specific contact.

• Testing: This plugin has been tested on Android only. The iOS implementation is provided but has not yet been tested.
