url_launcher

A Flutter plugin for launching a URL in the mobile platform. Supports iOS and Android.

Usage

To use this plugin, add url_launcher as a dependency in your pubspec.yaml file.

Example

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

void main() {
  runApp(Scaffold(
    body: Center(
      child: RaisedButton(
        onPressed: _launchURL,
        child: Text('Show Flutter homepage'),
      ),
    ),
  ));
}

_launchURL() async {
  const url = 'https://flutter.io';
  if (await canLaunch(url)) {
    await launch(url);
  } else {
    throw 'Could not launch $url';
  }
}

Supported URL schemes

The launch method takes a string argument containing a URL. This URL can be formatted using a number of different URL schemes. The supported URL schemes depend on the underlying platform and installed apps.

Common schemes supported by both iOS and Android:

Scheme	Action
`http:<URL>` , `https:<URL>`, e.g. `http://flutter.io`	Open URL in the default browser
`mailto:<email address>?subject=<subject>&body=<body>`, e.g. `mailto:smith@example.org?subject=News&body=New%20plugin`	Create email to <email address> in the default email app
`tel:<phone number>`, e.g. `tel:+1 555 010 999`	Make a phone call to <phone number> using the default phone app
`sms:<phone number>`, e.g. `sms:5550101234`	Send an SMS message to <phone number> using the default messaging app

More details can be found here for iOS and Android

Handling missing URL receivers

A particular mobile device may not be able to receive all supported URL schemes. For example, a tablet may not have a cellular radio and thus no support for launching a URL using the sms scheme, or a device may not have an email app and thus no support for launching a URL using the email scheme.

We recommend checking which URL schemes are supported using the canLaunch method prior to calling launch. If the canLaunch method returns false, as a best practice we suggest adjusting the application UI so that the unsupported URL is never triggered; for example, if the email scheme is not supported, a UI button that would have sent email can be changed to redirect the user to a web page using a URL following the http scheme.

Browser vs In-app Handling

By default, Android opens up a browser when handling URLs. You can pass forceWebView: true parameter to tell the plugin to open a WebView instead. On iOS, the default behavior is to open all web URLs within the app. Everything else is redirected to the app handler.
