import FastImage from 'react-native-fast-image'

const Imagegallery = () => (
    <FastImage
        style={{ width: 200, height: 200 }}
        source={{
            uri: 'https://unsplash.it/400/400?image=1',
            priority: FastImage.priority.normal,
        }}
        resizeMode={FastImage.resizeMode.contain}
    />
)

export default Imagegallery

A:

After installing react-native-fast-image you have to run pod command in you ios directory. 
So run this command :

cd ios
  pod install

Then run your project.
