Dart pub
A Flutter plugin for launching a URL in the mobile platform. Supports iOS and Android.
To use this plugin, add url_launcher as a dependency in your pubspec.yaml file.
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';
}
}
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
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.
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.
closeWebView failure on iOS.Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.
This was originally incorrectly pushed in the 4.2.0 update.
5.0.0 instead. That's the correctly versioned new push
of 4.2.0.launch to use async and await, fixed the incorrect return value by launch method.BAD. This was a breaking change that was incorrectly published on a minor version upgrade, should never have happened. Reverted by 4.2.0+3.
