Looks like you have a few issues here:

Java version OpenJDK Runtime Environment (build 1.8.0_242-release-1644-b01) X Android license status unknown. Try re-installing or updating your Android SDK Manager. Make sure to accept the licences for all your android sdks on your machine on Android Studio that you are working with.

You can run this command in order to accept all licences. yes | sdkmanager --licenses

Please take a look at community wiki's answer here for more information: Automatically accept all SDK licences

Is it just Android that's giving you issues? If so, then looks like you might have to delete the Android projects from your solution, and remake them.

You can run this command to do that: flutter create .

Since you already have Android config enabled then it should be fine. Please make sure to backup your project before you do this

Upgrade the flutter version from the stable channel. The most recent version is 1.22.0. Run this command here: flutter upgrade Then run this command: flutter upgrade doctor.

After you are done with this clean your project and rebuild your solution through the IDE that flutter is being developed on.
