Also you can import it and then use
<pre><code>import 'package:url_launcher/url_launcher.dart' as UrlLauncher;
UrlLauncher.launch(&quot;tel://21213123123&quot;)

Be sure to include an entry for it in the pubspec.yaml file, in the dependencies section:
<pre><code>url_launcher: ^1.0.2

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 =)

Then, after running this app and click the &quot;Dial a number&quot;, the System Phone App will bring up and make a call. (Unlike url_launcher, you don't need to press the Green Call button in the System Phone App)

You can do it by two ways:-
<ul>
<li>url_launcher package will be used to implement phone call using the default app of your mobile phone. This package will auto direct the phone to the default phone call making app and open the dialer screen to make the call.
</li>
<li>flutter_phone_direct_caller package is not the best package but we can implement direct phone calls directly from our phone without the intermediate dialer.
</li>
</ul>
Install the following dependencies inside your pubspec.yaml file:
<pre><code>dependencies:
 flutter:
 sdk: flutter
 cupertino_icons: ^1.0.0
 flutter_phone_direct_caller: ^1.0.1
 url_launcher: ^5.7.10
</code></pre>
Making Phone Calls using the &quot;flutter_phone_direct_caller&quot; : plugin
To implement the phone call using this plugin is really very easy. This package provides us FlutterPhoneDirectCaller class that provides us callNumber() method that takes a phone number.
<pre><code>_callNumber(String phoneNumber) async {
 String number = phoneNumber;
 await FlutterPhoneDirectCaller.callNumber(number);
}
</code></pre>
You can implement it in your button as follows
<pre><code>RaisedButton(
 child: Text(&quot;Call&quot;),
 onPressed: () {
 _callNumber(textEditingController.text);
 },

)
</code></pre>
Making Phone Calls using the &quot;url_launcher&quot;: plugin
This package provides us launch(URL) method that takes an URL with schema. Scheme is very essential as it directs the URL. In the case of phone calls, we use ‘tel:’ schema.
<pre><code>_launchPhoneURL(String phoneNumber) async {
 String url = 'tel:' + phoneNumber;
 if (await canLaunch(url)) {
 await launch(url);
 } else {
 throw 'Could not launch $url';
 }
}
</code></pre>
and to raised button:-
<pre><code>RaisedButton(
 child: Text(&quot;Call&quot;),
 onPressed: () {
 _launchPhoneURL(textEditingController.text);
 },
)
</code></pre>
IF you need advanced features you can use &quot;flutter_voip_kit&quot;, it is very new library, I have also not used it but it looks promising at first galance..

As on 13th August 2022, these are the latest updates :
This will work for Calls, SMS, Emails and Websites
Step 1:
Go to pubspec.yaml under Project
<blockquote>
pubspec.yaml
</blockquote>
and paste url_launcher : ^6.1.5 under dependencies:
( Click on <a href="https://pub.dev/packages/url_launcher" rel="noreferrer">https://pub.dev/packages/url_launcher</a> to get the latest version)
<pre><code>&gt; dependencies: 
 flutter:
&gt; sdk: flutter
&gt; 
&gt; url_launcher: ^6.1.5
</code></pre>
Then Run -
<blockquote>
Pub Get
</blockquote>
Go to AndroidManifest.xml under android/app/src/main/AndroidManifest.xml
<blockquote>
AndroidManifest.xml
</blockquote>
And paste the following codes for Phone calls, Sms, Email and Website under package=&quot;com.example......&quot; like so -
<pre><code>&lt;manifest xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
 package=&quot;com.codoweb.your project name&quot;&gt;




 &lt;!-- Provide required visibility configuration for API level 30 and above --&gt;
 &lt;queries&gt;
 &lt;!-- If your app opens https URLs --&gt;
 &lt;intent&gt;
 &lt;action android:name=&quot;android.intent.action.VIEW&quot; /&gt;
 &lt;data android:scheme=&quot;https&quot; /&gt;
 &lt;/intent&gt;
 &lt;!-- If your app sends emails --&gt;
 &lt;intent&gt;
 &lt;action android:name=&quot;android.intent.action.SEND&quot; /&gt;
 &lt;data android:mimeType=&quot;*/*&quot; /&gt;
 &lt;/intent&gt;
 &lt;!-- If your app checks for SMS support --&gt;
 &lt;intent&gt;
 &lt;action android:name=&quot;android.intent.action.VIEW&quot; /&gt;
 &lt;data android:scheme=&quot;sms&quot; /&gt;
 &lt;/intent&gt;

 &lt;data android:scheme=&quot;tel&quot; /&gt;
 &lt;/intent&gt;
 &lt;/queries&gt;
</code></pre>
Now use the following codes for activating :
<pre><code> import 'package:flutter/material.dart';
 import 'package:url_launcher/url_launcher.dart';
 
 void main() {
 runApp(const MyApp());
 }
 
 class MyApp extends StatelessWidget {
 const MyApp({Key? key}) : super(key: key);
 
 @override
 Widget build(BuildContext context) {
 return MaterialApp(

 }
 }
 
 class MyHomePage extends StatelessWidget {
 const MyHomePage({Key? key}) : super(key: key);
 
 @override
 Widget build(BuildContext context) {
 return Scaffold(
 appBar: AppBar(
 backgroundColor: Colors.black,
 centerTitle: true,

canLaunch() 
launch()

I try to make a phone call from my Flutter app. With the following code:
<pre><code>UrlLauncher.launch('tel: xxxxxxxx');
</code></pre>
I found this Function on the GitHub flutter repo: <a href="https://github.com/flutter/flutter/issues/4856" rel="noreferrer">https://github.com/flutter/flutter/issues/4856</a>
But this doesn't work for me. Is this Function still in Flutter and in which package? Or is there a better option to do a phone call from my app?
