Answer 1

You are having 3 options:

1. You can open your emulator in Android Studio and after that debug your application from VSCode.

2. You can also check whether adb(Android debugger bridge) is installed in your machine or not.

3. Or else you can run your application in a real device.

Answer 2

My problem was solved by this command

flutter config --android-sdk <sdk-location>
