How can I get the actual page from the onPageChange event?

See original GitHub issue

<Carousel onPageChange={ self.myFunction() }> { array } </Carousel>

@sergioribeiro you can know that with the index passed in onPageChange. See this sample:

  state = {
    words: [
      'foo',
      'bar'
    ]
  };

  handleOnPageChange(pageIndex) {
    if (pageIndex === this.state.words.length - 1) {
      console.log('we reached the end!');
    }
  }

  render() {
    const pages  = this.state.words.map(w => <Text key={w}>{w}</Text>);
    return (
      <View style={styles.container}>
        <Carousel
          initialPage={ 1 }
          pageStyle={ {backgroundColor: 'white', borderRadius: 5} }
          onPageChange={ this.handleOnPageChange.bind(this) }
        >
          { pages }
        </Carousel>        
      </View>
    );
  }

Let me know if that helps.
