Flutter URL Launcher Example

As a part of the flutter tutorial series, we’re going to explore the URL launcher example. Here we’re going to use a package called url_launcher

Usage:

• To open phone dialer / SMS app
• Open website in external browser
• Send email using a mailer app
• or open any app using a custom URL scheme.

Getting started

To work with our example, first, we need to create a new project or you can choose any existing flutter project.

flutter create learnflutter
cd learnflutter

Once the project is created, we need to add url_launcher package in pubspec.yaml file

dependencies:
  url_launcher: ^5.7.10

Then execute flutter pub get to install all required packages

Flutter URL Launcher example

 _launch(url) async {
    if (await canLaunch(url)) {
      await launch(url);
    } else {
      print("Not supported");

  }

When we pass the URL inside _launch(), we can open an app such as the dialer, SMS, WhatsApp, and more.
