How to get the Default Calendar in Android using the Expo SDK Calendar API?

SOLVED: Used await and a variable to store the promise.

I am trying to insert an event into the default calendar on an android device using react-native and expo sdk. Previously, one could create an event using the createEventAsync() method with the 1st argument as Calendar.DEFAULT but that is no longer supported. I can use the getCalendarsAsync() method to get all calenders but the object I am getting back is making no sense. Some code: 

async addReservationToCalendar(date) {
    await this.obtainCalendarPermission();
    console.log(Calendar.getCalendarsAsync());
}

Someone had suggested that I could iterate through the responses to find a calendar with the isPrimary attribute set to true but I don't see how I achieve this. I have already gotten the permission and I am receiving the following promise as a response. Promise { "_40": 0, "_55": null, "_65": 0, "_72": null, }.
What do I need to do to set a calendar event on an android device using the expo Calendar API ?

Solution

  • Because that's a promise, you need to do like this

    Calendar.getCalendarsAsync().then(calendars => console.log(calendars))
