[iOS17] call to Add2Calendar.addEvent2Cal never returns

[sperochon]

Hello,

Using:
Flutter 3.16.5
add_2_calendar 3.0.1
Testing on iPhone with iOS 17
And compiling with Xcode 15 + sdk iOS 17

The issue is:
the call to addEvent2Cal never returns. It is stuck (= the second line return isNativeCalendarShown; is never executed)

final isNativeCalendarShown = await Add2Calendar.addEvent2Cal(event);
return isNativeCalendarShown;

After spending a few hours, I've finally found the cause of this bug which is only 1 missing line 🤯😭. The fix #136 forgot to call completion callback completion?(true) line 105 of file Add2CalendarPlugin.swift

if #available(iOS 17, *) {
    OperationQueue.main.addOperation {
        self.presentEventCalendarDetailModal(event: event, eventStore: eventStore)
    }
}

should be

if #available(iOS 17, *) {
    OperationQueue.main.addOperation {
        self.presentEventCalendarDetailModal(event: event, eventStore: eventStore)
    }
    completion?(true)
}

Thanks

It seems that the PR #150 will indirectly fix this issue too when it will be merged on master...
