Error on Flutter with the URL_Launcher package

Question

Since yesterday, when I use a GestureDetector with the url_launcher package I'm getting this error:

Any thoughts?

Answer 1

From API30 (Android 11) onwards, your Android app has to list all apps it interacts with.

Add this in your android manifest file (android > app > src > main > AndroidManifest.xml)

<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>

Install the package properly using the steps given here. You should add a dependency of url_launcher in pubspec.yaml file. If you have done that,

To solve this issue you should clean the project using flutter clean, and then you upgrade your flutter using flutter upgrade. This will solve the problem for sure. If not, you create a new project and then paste the code in it.
