Making Calls in Flutter

Making calls in Flutter refers to the process of integrating phone call functionality into a Flutter application, allowing users to initiate phone calls directly from within the app. This functionality is achieved by leveraging the device’s default phone app through the use of Uniform Resource Identifiers (URIs) with the tel scheme. By launching a tel URI with the desired phone number, Flutter apps can trigger the system to open the phone app with the provided number pre-filled, enabling users to confirm and initiate the call.

In the below PDF we discuss about Making Calls in Flutter in detail in simple language, Hope this will help in better understanding.

Steps to Making Calls in Flutter:

Here are the steps to making calls in a Flutter application:

1. Add Permission:
Before making calls, your Flutter app needs permission to access the device’s phone functionality. For Android, add the CALL_PHONE permission to your AndroidManifest.xml file. For iOS, add the NSAllowsLocalNetworking key to your Info.plist file.

2. Integrate the URL Launcher Plugin:
Flutter provides the url_launcher plugin, which allows you to open URLs in the device’s default browser, email app, or phone app. Add this plugin to your pubspec.yaml file and import it into your Dart code.

sdk: flutter
url_launcher: ^6.0.4

3. Implement the Call Functionality:
Create a function to initiate phone calls using the tel URI scheme. Check if the device can launch the URL and then launch the phone app with the provided number.

import 'package:url_launcher/url_launcher.dart';

void makePhoneCall(String phoneNumber) async {
final url = 'tel:$phoneNumber';
if (await canLaunch(url)) {
await launch(url);
} else {
throw 'Could not launch $url';

4. UI Integration:
Integrate the makePhoneCall function into your app’s user interface, such as a button labeled “Call Support” or “Contact Us.” When the user taps the button, invoke the makePhoneCall function with the appropriate phone number.

onPressed: () {
child: Text('Call Support'),

5. Testing and Error Handling:
Thoroughly test the call functionality on different devices and scenarios to ensure compatibility and reliability. Handle errors gracefully, providing clear feedback to the user if the call cannot be initiated.

By following these steps, you can seamlessly integrate phone call functionality into your Flutter application, enhancing its usability and user experience.


In conclusion, Integrating phone call functionality into your Flutter app can greatly enhance its usability and user experience. By following the steps outlined in this guide and adhering to best practices, you can seamlessly incorporate this feature into your application, providing users with a convenient way to connect with your business or service.
