Here, in the above code, while running it in metro bundler, using expo run android command, the app is running properly in expo without any issue or error. But When I build the apk using expo build:android, and try to install it in my physical device, then it's showing the splash screen and after that it is showing the white blank screen. Not routing to Login component or DashBoard component either
