I get this error when I try to Build Signed APK. I recently upgraded to API 23 but Generated APK:s successfully after that. Im confused. Asking for help and advise how to solve
open key.properties and check your path is correct. (replace from \ to /)
example:-
replace from "storeFile=D:\Projects\Flutter\Key\key.jks" to "storeFile=D:/Projects/Flutter/Key/key.jks"
