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(new Scaffold(
body: new Center(
child: new RaisedButton(
onPressed: _launchURL,
child: new 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 |
tel:<phone number>, e.g. tel:+1 555 010 999 |
Make a phone call to |
sms:<phone number>, e.g. sms:5550101234 |
Send an SMS message to |

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.
