Fork of url_launcher that enables zoom controls and defaults to zoomed out view. Parent url_launcher package was zooming in on images when opening.
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.dev';
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.dev |
Open URL in the default browser |
mailto:<email address>?subject=<subject>&body=<body>, e.g. mailto:[email protected]?subject=News&body=New%20plugin |
Create email to in the default email app |
tel:<phone number>, e.g. tel:+1 555 010 999 |
Make a phone call to using the default phone app |
sms:<phone number>, e.g. sms:5550101234 |
Send an SMS message to 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.
