How to Programmatically call a phone number in flutter

In Flutter, you can initiate a phone call by using the url_launcher package. This package allows you to open URLs, including phone numbers, in the device’s default application, which is typically the phone app for phone numbers. Here’s how you can call a phone number in Flutter:

Step 1: Add the Dependency

First, add the url_launcher dependency to your pubspec.yaml file:

    sdk: flutter
  url_launcher: ^6.0.3

Then, run flutter pub get to fetch the package.

Step 2: Import the Package

In your Dart code, import the url_launcher package:

import 'package:url_launcher/url_launcher.dart';

Step 3: Implement the Phone Call Function

You can create a function to make a phone call using the launch method from the url_launcher package. Here’s an example:

void makePhoneCall(String phoneNumber) async {
  final Uri _phoneLaunchUri = Uri(scheme: 'tel', path: phoneNumber);
  if (await canLaunch(_phoneLaunchUri.toString())) {
    await launch(_phoneLaunchUri.toString());
  } else {
    throw 'Could not launch $_phoneLaunchUri';

In this example, the makePhoneCall function takes a phone number as a parameter, creates a tel URI, checks if the device is capable of launching the URI, and then calls launch to open the phone app with the specified phone number.

Step 4: Use the Function to Make a Call

You can now use the makePhoneCall function to make a phone call. For example, you might have a button that triggers the call:

  onPressed: () {
    makePhoneCall('123-456-7890'); // Replace with the desired phone number
  child: Text('Call'),

When the button is pressed, it will initiate a phone call to the specified phone number.

Remember to replace '123-456-7890' with the actual phone number you want to call.

Step 5: Request Permissions (Optional)

In some cases, you might need to request permission to make phone calls. If your app targets Android API level 30 or higher, you’ll need to add the CALL_PHONE permission to your AndroidManifest.xml file and request permission at runtime. On iOS, you don’t need to request permission to make phone calls.

That’s it! You’ve now implemented phone call functionality in your Flutter app using the url_launcher package. Users can initiate a call by tapping the button or triggering the makePhoneCall function programmatically.
