Flutter Telephony not recieving sms in real hardware except emulator - flutter

Question

I am using telephony dependencies for receive_sms.
It is working fine in the emulator and I receive every message sent, but it is not working on a real hardware phone.
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:telephony/telephony.dart';
onBackgroundMessage(SmsMessage message) {
debugPrint("onBackgroundMessage called");
}
void main() {
runApp(MyApp());
}
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
String _message = "";
final telephony = Telephony.instance;
#override
void initState() {
super.initState();
initPlatformState();
}
onMessage(SmsMessage message) async {
setState(() {
_message = message.body ?? "Error reading message body.";
});
}
onSendStatus(SendStatus status) {
setState(() {
_message = status == SendStatus.SENT ? "sent" : "delivered";
});
}
// Platform messages are asynchronous, so we initialize in an async method.
Future<void> initPlatformState() async {
// Platform messages may fail, so we use a try/catch PlatformException.
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
final bool? result = await telephony.requestPhoneAndSmsPermissions;
if (result != null && result) {
telephony.listenIncomingSms(
onNewMessage: onMessage, onBackgroundMessage: onBackgroundMessage);
}
if (!mounted) return;
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Center(child: Text("Latest received SMS: $_message")),
TextButton(
onPressed: () async {
await telephony.openDialer("123413453");
},
child: Text('Open Dialer'))
],
),
));
}
}
I made sure the correct permissions are added in the Android Manifest file. I asked for the RECEIVE_SMS and BROADCAST_SMS permissions and it appears to be working since I can receive messages in the emulator.
What am I doing wrong?

Answer 1

Try asking for permission before you start listening to the message.
bool permissionsGranted = await telephony.requestPhoneAndSmsPermissions;
here are listed permission required and how to ask.

Answer 2

Make sure you added these permission in manifest.
<manifest>
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<application>
...
...
<receiver android:name="com.shounakmulay.telephony.sms.IncomingSmsReceiver"
android:permission="android.permission.BROADCAST_SMS" android:exported="true">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
</application>
</manifest>
