Step 1: Set Up Your Flutter Environment

Ensure you have Flutter installed on your machine. If not, follow the installation guide on the official Flutter website.

Step 2: Create a New Flutter Project

Open your terminal or command prompt, navigate to your desired directory, and create a new Flutter project:

flutter create url_launcher_demo

Navigate into your project directory:

cd url_launcher_demo

Step 3: Add url_launcher Dependency

Open the pubspec.yaml file in your Flutter project and add the url_launcher dependency:

    sdk: flutter
  url_launcher: ^6.3.0

Run flutter pub get to install the new dependency:

flutter pub get

Step 4: Modify the Main Dart File

Open the lib/main.dart file and replace its contents with the following code:

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

void main() {

class UrlLauncherDemo extends StatelessWidget {
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text("Flutter URL Launcher Demo"),
        body: Center(
          child: ElevatedButton(
            onPressed: _launchURL,
            child: Text("Open YouTube Video"),

Future _launchUrl() async {
  final Uri _url = Uri.parse(""); // Replace with your YouTube video URL

  if (!await launchUrl(_url)) {
    throw Exception("Could not launch $_url");

Step 5: Update Android Configuration

For Android, you need to ensure that you have the appropriate permissions. Open android/app/src/main/AndroidManifest.xml and ensure it contains the following permissions within the <manifest> tag:

<uses-permission android:name="android.permission.INTERNET"/>

Step 6: Update iOS Configuration

For iOS, you need to update the Info.plist file. Open ios/Runner/Info.plist and add the following lines inside the <dict> tag:


Step 7: Run the App

Now that everything is set up, you can run your app using the following command:

flutter run

This will start the app on an available emulator or connected device.

How the App Works

  • UrlLauncherDemo Widget: This stateless widget contains a Scaffold with an AppBar and a Centered ElevatedButton.
  • _launchURL Method: This method uses the url_launcher package to launch the specified URL in the default web browser.
  • main Function: This function starts the Flutter app by running the UrlLauncherDemo widget.


You have now created a simple Flutter app that opens a YouTube video using the url_launcher package. By following these steps, you can easily extend this functionality to open other URLs or handle other types of links within your Flutter applications.
