const handleMomentumScrollEnd = (event) => {
    
    const offsetX = event.nativeEvent.contentOffset.x;
    const offsetY = event.nativeEvent.contentOffset
    console.log("off set y",offsetY);
    const index = Math.round(offsetX / Dimensions.get('window').width);
    console.log("handle momentum",index);
    setSelectedPageIndex(index);
    console.log("handle momment scroll end");
    

    
  };

  const renderContentPages = (item) => {

    const words = item.content.split(' ');
    const totalPages = Math.ceil(words.length / wordsPerPage);

    return Array.from({ length: totalPages }, (_, pageIndex) => {
      const startIdx = pageIndex * wordsPerPage;
      const endIdx = startIdx + wordsPerPage;
      const pageWords = words.slice(startIdx, endIdx).join(' ');

      return (
        <View key={pageIndex} style={{width:contentWidth}}>
          <Text>{item.title}</Text>
          <Text style={ [{padding:30, fontSize:fontSizeOfBookRead,fontWeight:fontWeightOfBookRead }]}>{pageWords}</Text>
          <Text>{pageIndex+1 }</Text>
          <Text>{item.title.split(" ")[1]}</Text>
        </View>
      );
    });
  };

  <FlatList
            style={{width:contentWidth}}
            horizontal
            pagingEnabled
            data={filteredChapters} // 
            keyExtractor={(item, index) => {
              item.chapId.toString()
              console.log("itemindex",index);
            }}
            onMomentumScrollEnd={handleMomentumScrollEnd}
            ref={scrollViewRef}
            renderItem={({ item }) => (
              renderContentPages(item)
              )}
          />
