Everything works perfectly when in debug mode. It first happened when I update Flutter version to 1.10.x I could not remember which version did I use, properly. It should be 1.7.8, it was stable. To fix it I downgrade the flutter to 1.7.8+4 and also downgrade firebase related pub packages. But error still here.
