React Native component that helps with determining whether a component is visible to the user.

Inspired by react-native-inviewport and react-visibility-sensor.

All usable with Expo with no extra native dependencies!

🐶 visible Horizontal?	🐶 visible Vertical ?

Open a Terminal in the project root and run:

npm install @svanboxel/visibility-sensor-react-native

or if you use yarn:

yarn add @svanboxel/visibility-sensor-react-native

import VisibilitySensor from '@svanboxel/visibility-sensor-react-native'

const Example = props => {
  const handleImageVisibility = visible => {
    // handle visibility change
  }

  render() {
    return (
      <View style={styles.container}>
        <VisibilitySensor onChange={handleImageVisibility}>
          <Image
            style={styles.image}
            source={require("../assets/placeholder.png")}
           />
         </VisibilitySensor>
    </View>
   )
  }
}

It's not finished and some work has to be done yet.

• Handle offsets. Callback if triggered is 1px is in viewport now.
• Add correct Typescript types
• Add tests
