React Native local assets images not showing

I built a new react native app(react native init), and upload it to github,All was good and I saw the images.

I downloaded the branch to check it.

The Problem -

I don't see local assets in Android and in iOS

I tried to run this command and it created "index.android.bundle" but it didn't help

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/
