Build failed due to url_launcher_android flutter?

Question

In my pubspec.yml I didn't add any library named url_launcher. But, In somewhere some library might be used this, that I don't know.

And, after

clean gradle
build gradle(its takes too much time approx. 3 hr.)

I got following exception in build.

> Task :url_launcher_android:testDebugUnitTest

Android # Add any URL schemes passed to canLaunchUrl as entries in your AndroidManifest.xml, otherwise, it will return false in most cases starting on Android 11 (API 30) or higher. A element must be added to your manifest as a child of the root element.
