How to make a phone call from a flutter app

This worked for me

use this plugin

import 'package:flutter/material.dart';
    import 'dart:async';
    
    import 'package:flutter/services.dart';
    import 'package:flutter_phone_direct_caller/flutter_phone_direct_caller.dart';
    
    void main() => runApp(new MyApp());
    
    class MyApp extends StatefulWidget {
      @override
      _MyAppState createState() => new _MyAppState();
    }
    
    class _MyAppState extends State<MyApp> {
      TextEditingController _numberCtrl = new TextEditingController();
    
      @override
      void initState() {
        super.initState();
        _numberCtrl.text = "085921191121";
      }
    
      @override
      Widget build(BuildContext context) {
        return new MaterialApp(
          home: new Scaffold(
            appBar: new AppBar(
              title: const Text('Plugin example app'),
            ),
            body: new Column(
              children:<Widget>[
                Padding(
                  padding: EdgeInsets.all(8.0),
                  child: TextField(
                    controller: _numberCtrl,
                    decoration: InputDecoration(
                      labelText: "Phone Number"
                    ),
                    keyboardType: TextInputType.number,
                  ),
                ),
                RaisedButton(
                  child: Text("Test Call"),
                  onPressed: () async{
                    FlutterPhoneDirectCaller.callNumber(_numberCtrl.text);
                  },
                )
              ]
            ),
          ),
        );
      }
    }

You should add this in your pubspec.yaml => url_launcher: ^5.0.2 then you click Packages get .

in your code you add the import : import 'package:url_launcher/url_launcher.dart' as UrlLauncher; Hope it works =)

import 'package:url_launcher/url_launcher.dart' as UrlLauncher;


    UrlLauncher.launch('tel:+${p.phone.toString()}')

        //if mail 
     UrlLauncher.launch('mailto:${p.email}'),

url_launcher is universal package for launching url, dialing number and sending mail.

1. Add url_launcher: ^5.5.2 to pubspec.yaml file and run flutter pub get
2. Import package import 'package:url_launcher/url_launcher.dart';
3. Define function:

void launchUrl(String url) async {
  if (await canLaunch(url)) {
    launch(url);
  } else {
    throw "Could not launch $url";
  }
}

4. Call your universal function for different purposes:

//for launching url
launchUrl("HTTP://example.com");

// for dial phone number
launchUrl("tel:+99364921507"); 

// for sending email
launchUrl("mailto:[email protected]?subject=Meeting&body=Can we meet via Google Meet"); 

Call the launch method from url_launcher package:

launch("tel://214324234");

Here's the complete code:

import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter Demo',
      home: new Home(),
    );
  }
}

class Home extends StatelessWidget {
  Home({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) => new Scaffold(
        appBar: new AppBar(
          title: new Text("View"),
        ),
        body: new Center(
          child: new FlatButton(
              onPressed: () => launch("tel://21213123123"),
              child: new Text("Call me")),
        ),
      );
}

void main() {
  runApp(
    new MyApp(),
  );
}

Also you can import it and then use

import 'package:url_launcher/url_launcher.dart' as UrlLauncher;
UrlLauncher.launch("tel://21213123123")

Be sure to include an entry for it in the pubspec.yaml file, in the dependencies section:

url_launcher: ^1.0.2
