Installation

Terminal

If you're installing this in a bare React Native app, you should also follow these additional installation instructions.

Configuration

You must add the following permissions to your app.json.

  • Android requires READ_CALENDAR & WRITE_CALENDAR inside the expo.android.permissions array.
  • iOS requires the NSRemindersUsageDescription key be added to expo.ios.infoPlist with a string value describing the reason for the permission request.
