PS D:\FlutterProjects\NewLedgersFlutter\ledgers_lite_flutter> flutter doctor --android-licenses
Error: Could not find or load main class KUMAR
Caused by: java.lang.ClassNotFoundException: KUMAR

Note: I am developing a Flutter project which is giving the above errors when I try to run the application

I have tried with flutter doctor --android-licenses but it's not resolving the issues.

Can you provide us with the output after you use `flutter doctor --android-licenses` please. — 3Bady, Jul 07 '21 at 08:35

In dropdown list open "plugins"
Search for "flutter" and install this plugin together with dart.
Restart the Android Studio and open a new terminal.

Setting "android-studio-dir" value to "C:\Program Files\Android\Android Studio". You may need to restart any open editors for them to read new settings. – Vishali Jul 07 '21 at 08:44
if you got android license status unknown try `flutter doctor --android-licenses` – Ravindra S. Patil Jul 07 '21 at 08:59
flutter and dart plugins are already installed – Vishali Jul 07 '21 at 09:02

It should work if you installed Android Studio;

flutter config --android-studio-dir="YOUR ANDROID STUDIO PATH"

then type flutter doctor to see if it worked

To solve android licence error run;

flutter doctor --android-licenses

then check it with flutter doctor

You need Android SDK Command Line Tools installed. If you're using Android Studio go in Preferences -> Appearance & Behaviour -> System Settings -> Android SDK then select the SKL tools tab and install the latest Android SDK Command Line Tools Did it resolve? – Muhtar Jul 07 '21 at 08:54
