I can get any emulators running in vs code
As explicitly stated, you have No suitable Android AVD system images available. Create the AVD through Android Studio first so you can easily download a system image with a click.
Open Android Studio -> Configure -> AVD Manager -> Run Your Virtual DeviceVisual studio code -> View -> Command palette... -> Flutter: Select Device -> choose your android device
You have to start Android Studio run the emulator first, before running a flutter project.
