const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
 
  url: {
    color: 'red',
    textDecorationLine: 'underline',
  },
 
  email: {
    textDecorationLine: 'underline',

  text: {
    color: 'black',
