How to listen to Phone Calls in flutter App?

I'll try to ask it in as simple a way as I can. If my app is running in foreground and, I get a phone call at that very moment, is there any way I can call a function/perform an operation when this happens?

// My App is open at any random time call received
(if call_Received) { // How do I do this bit via dart code?
 sample()
}

void sample() { // Any random function
  // Some code to perform
}

I personally use flutter_phone_state plugin and it works fine for me. But the package on the pub pub.dev is outdated and no longer maintained. So add below git url on pubspec.yaml instead.

  flutter_phone_state:
    git:
      url: https://github.com/SimformSolutionsPvtLtd/flutter_phone_state.git
      ref: feature/null-safety

Please check https://pub.dev/packages/phone_state. I believe it will work for you. If you still having an issue with that, Please let me know.

Example snippet:

import 'dart:io';
import 'package:flutter/material.dart';
import 'package:permission_handler/permission_handler.dart';
import 'package:phone_state/phone_state.dart';

main() {
  runApp(
    const MaterialApp(
      home: Example(),
    ),
  );
}

class Example extends StatefulWidget {
  const Example({Key? key}) : super(key: key);

  @override
  _ExampleState createState() => _ExampleState();
}

class _ExampleState extends State<Example> {
  PhoneStateStatus status = PhoneStateStatus.NOTHING;
  bool granted = false;

  Future<bool> requestPermission() async {
    var status = await Permission.phone.request();

    switch (status) {
      case PermissionStatus.denied:
      case PermissionStatus.restricted:
      case PermissionStatus.limited:
      case PermissionStatus.permanentlyDenied:
        return false;
      case PermissionStatus.granted:
        return true;
    }
  }

  @override
  void initState() {
    super.initState();
    if (Platform.isIOS) setStream();
  }

  void setStream() {
    PhoneState.phoneStateStream.listen((event) {
      setState(() {
        if (event != null) {
          status = event;
        }
      });
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text("Phone State"),
        centerTitle: true,
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          crossAxisAlignment: CrossAxisAlignment.center,
          children: [
            if (Platform.isAndroid)
              MaterialButton(
                child: const Text("Request permission of Phone"),
                onPressed: !granted
                    ? () async {
                        bool temp = await requestPermission();
                        setState(() {
                          granted = temp;
                          if (granted) {
                            setStream();
                          }
                        });
                      }
                    : null,
              ),
            const Text(
              "Status of call",
              style: TextStyle(fontSize: 24),
            ),
            Icon(
              getIcons(),
              color: getColor(),
              size: 80,
            )
          ],
        ),
      ),
    );
  }

  IconData getIcons() {
    switch (status) {
      case PhoneStateStatus.NOTHING:
        return Icons.clear;
      case PhoneStateStatus.CALL_INCOMING:
        return Icons.add_call;
      case PhoneStateStatus.CALL_STARTED:
        return Icons.call;
      case PhoneStateStatus.CALL_ENDED:
        return Icons.call_end;
    }
  }

  Color getColor() {
    switch (status) {
      case PhoneStateStatus.NOTHING:
      case PhoneStateStatus.CALL_ENDED:
        return Colors.red;
      case PhoneStateStatus.CALL_INCOMING:
        return Colors.green;
      case PhoneStateStatus.CALL_STARTED:
        return Colors.orange;
    }
  }
}

you can use https://pub.flutter-io.cn/packages/phone_state_i but you must customize this package because you will receive a build error when you want to build apk. so customize the package and change compileSdkVersion from 27 to 28. for more information, you can see issues part of package.

As https://pub.dev/packages/phonecallstate#-example-tab-package is not working u can use new package phone_state_i 0.0.3 with https://pub.dev/packages/phone_state_i#-readme-tab-

import 'package:phone_state_i/phone_state_i.dart';

phoneStateCallEvent.listen((PhoneStateCallEvent event) {
      print('Call is Incoming/Connected' + event.stateC);
      //event.stateC has values "true" or "false"
});
