Flutter: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag
2,370
Just had the same problem with the new Version of the urlLauncher 4.0.2 Plugin
I downgraded to 3.0.3 and everything worked fine so there might be a bug inside the repository.
pubspec.yaml
url_launcher: 3.0.3
Sample Code (taken from the git repo but it works for me with 3.0.3)
https://github.com/flutter/plugins/tree/master/packages/url_launcher
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';
}
}
For all avaiable versions of the Plugin see here. https://pub.dartlang.org/packages/url_launcher#-changelog-tab-

launch("tel://21213123123")
But, I'm getting the following error!
PlatformException (PlatformException(error, Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?, null))

Here is my error log
