Exception in callNumber function when called from FCM BackgroundMessage

[tanmaysathe]

Is it supported using callNumber function in background message?

Following is the code:

import 'dart:async';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';
import 'package:firebase_messaging/firebase_messaging.dart';
import 'package:flutter_phone_direct_caller/flutter_phone_direct_caller.dart';

Future<void> _messageHandler(RemoteMessage message) async {
  await Firebase.initializeApp();
  String num = message.data['number'];
  if (num.isNotEmpty) {
    await FlutterPhoneDirectCaller.callNumber(num);
  }
}
Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  FirebaseMessaging.onBackgroundMessage(_messageHandler);
  await FirebaseMessaging.instance.subscribeToTopic('demo_topic');
}

Following is the exception message:
