The alarm is not working

I tried to add an calendar event with alarm: RNCalendarEvents.saveEvent(Alert for taking pills, { notes: data[1], description: data[2], startDate: start, endDate: end, recurrence: ‘daily’, calendar: [‘Calendar’], alarm: [{ date: -1 }], }) .then(id => { // we can get the event ID here if we need it }).catch(error => console.log('Save Event Error: ', error));

Then in the system calendar, I can see the event is created, however, the alert is none. Also there is no notification/alert one minus before the event starts. Am I doing something wrong in creating the event? Thanks.

From what I see from the source code, on iOS the date needs to be iso string, however on Android, the date needs to be number (which is used as minutes, e.g. given date: 2, in Android it will convert to 2 minutes before)

It’s better to do a branching on Platform, e.g.

[
        {
            date:
                Platform.OS === 'ios'
                    ? moment(startsOnDate)
                          .subtract(2, 'hours')
                          .toISOString()
                    : moment.duration(2, 'hours').asMinutes(),
        }
]
