error with react-native-fast-image-expo

Expo Development Tools
1

I have installed react-native-fast-image-expo here
https://www.npmjs.com/package/react-native-fast-image-expo

I installed and linked exactly as the documentation mentions.
in my app I am simply importing and attempting to use it.
import FastImage from “react-native-fast-image-expo”;
render () …

<FastImage
        style={styles.image}
        source={{
          uri: "https://unsplash.it/400/400?image=1",
          headers: { Authorization: "someAuthToken" },
          priority: FastImage.priority.normal
        }}
        resizeMode={FastImage.resizeMode.contain}
      />

I get this error on both ios and android

requireNativeComponent: “FastImageView” was not found in the UIManager.
Any ideas ? Do i need to eject in order to use ‘react-native-fast-image’
Thanks!

NOTE

The original answer is out of date.

Now that EAS Build exists it is no longer needed to “eject” (which is called prebuild now) to use a library like this.

Original answer

Yes, you will have to eject.

Whenever you have to run react-native link it means you have to eject, unless Expo already includes the package.
