React Native Text Ticker/Marquee Component
npm install react-native-text-ticker- Don't scroll the text if it fits in the container

import { StyleSheet, View } from 'react-native'
import TextTicker from 'react-native-text-ticker'export default class Example extends PureComponent {
render(){
return(
duration={3000}
loop
bounce
repeatSpacer={50}
marqueeDelay={1000}

Super long piece of text is long. The quick brown fox jumps over the lazy dog.
)

}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',

react-native-text-ticker supports a single child text string, any other use may give unexpected behaviour.
