How to find out from code if my Android app runs on emulator or real device?

Question

I have read this stackoverflow thread already and I tried using the code given in that answer to find out if I run my code on the emulator or on a real device:

Answer 1

This is the standard google flutter emulator check :

public boolean isEmulator() {
    return (Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic"))
            || Build.FINGERPRINT.startsWith("generic")
            || Build.FINGERPRINT.startsWith("unknown")
            || Build.HARDWARE.contains("goldfish")
            || Build.HARDWARE.contains("ranchu")
            || Build.MODEL.contains("google_sdk")
            || Build.MODEL.contains("Emulator")
            || Build.MODEL.contains("Android SDK built for x86")
            || Build.MANUFACTURER.contains("Genymotion")
            || Build.PRODUCT.contains("sdk_google")
            || Build.PRODUCT.contains("google_sdk")
            || Build.PRODUCT.contains("sdk")
            || Build.PRODUCT.contains("sdk_x86")
            || Build.PRODUCT.contains("vbox86p")
            || Build.PRODUCT.contains("emulator")
            || Build.PRODUCT.contains("simulator");
}
