Recurrent event has error on samsung/huawei

Describe the bug can't create forever recurrent event on samsung s10, also failed on huawei mate30.

To Reproduce on samsung s10, I add a recurrent event, with following Event param:

    var calendarEvent = Event(
      "calendarId",
      reminders: [Reminder(minutes: 0)],
      title: "title",
      description: "description",
      start: startTime,
      end: endTime,
      recurrenceRule: RecurrenceRule(
        RecurrenceFrequency.Daily,
        interval: 1,
      ),
    );

but, it only create serveral events, not forever.

Expected behavior create forever recurrent event.

Device(s) tested This can be very important as not all device vendors do calendar in the same way.

Additional context I checked the plugins source code, maybe the following function caused it?

private fun buildEventContentValues(event: Event, calendarId: String): ContentValues {
        val values = ContentValues()
        val duration: String? = null
        values.put(Events.ALL_DAY, event.eventAllDay)
        values.put(Events.DTSTART, event.eventStartDate!!)
        values.put(Events.EVENT_TIMEZONE, getTimeZone(event.eventStartTimeZone).id)
        values.put(Events.DTEND, event.eventEndDate!!)
        values.put(Events.EVENT_END_TIMEZONE, getTimeZone(event.eventEndTimeZone).id)
        values.put(Events.TITLE, event.eventTitle)
        values.put(Events.DESCRIPTION, event.eventDescription)
        values.put(Events.EVENT_LOCATION, event.eventLocation)
        values.put(Events.CUSTOM_APP_URI, event.eventURL)
        values.put(Events.CALENDAR_ID, calendarId)
        values.put(Events.DURATION, duration)
        values.put(Events.AVAILABILITY, getAvailability(event.availability))

        if (event.recurrenceRule != null) {
            val recurrenceRuleParams = buildRecurrenceRuleParams(event.recurrenceRule!!)
            values.put(Events.RRULE, recurrenceRuleParams)
        }
        return values
    }

because I found the description on android doc of android CalendarContract.Events:

Insert

When inserting a new event the following fields must be included:

dtstart
dtend if the event is non-recurring
duration if the event is recurring
rrule or rdate if the event is recurring
eventTimezone
a calendar_id

as above source code, the plugin only set DTEND, and set DURATION null.

and I also test android api, and set ContentValue that 1.no Events.DTEND 2.Events.DURATION = "PT1H" and it can create recurrent event succesfully.
