} from 'react-native'
class AnimationExample extends React.Component {
constructor () {
super()
this.animValue = new Animated.Value(0)
}
componentDidMount () {
this.animate()
}
animate () {
this.animValue.setValue(0)
Animated.timing(
this.animValue,
{
toValue: 1,
duration: 4000,
easing: Easing.linear
}
).start(() => this.animate())
}
render () {
const anim = this.animValue.interpolate({
inputRange: [0, 1],
outputRange: ['0deg', '360deg']
})
return (
<View style={styles.container}>
<Animated.Image
style={{
width: 227,
height: 200,
transform: [{rotate: anim}] }}
source={{uri: 'https://s3.amazonaws.com/media-p.slid.es/uploads/alexanderfarennikov/images/1198519/reactjs.png'}}
