react-native-fast-image: requireNativeComponent: "FastImageView" was not found in the UIManager.

Came across the same working on the iOS Simulator. Running pod install and rebuilding the app fixed it for me.

having the same issue on android, I’m not using Expo.

resolved by re-building app

I found that this package is not available in expo yet 😦

for me, solved by pod repo update and pod install

I resolved rebuilding app, I’m using react-native CLI and testing in a real tablet via cable, i used the command “yarn start --reset-cache” and “yarn android” and everything works fine.

FastImage can only be used in Expo with a custom development client. See the pinned response. You have to do some reading to understand how it works but after you get your dev client built with Expo EAS FastImage works out of the box.

make sure you reinstall podfile in ios folder
