PreloadPageView #

Like the name, this is the widget to support Pre-load function for PageView widget.

For better user experience sometimes we need pre-load the images/web requests before user really scrolled to next PageView but the official PageView don't support that.So this is the time to use PreloadPageView.

Usage #

Everything is similar like PageView, you need PreloadPageView.builder and PreloadPageController to create the PreloadPageView.

Also you can use preloadPagesCount to set preload pages count when you need.

Example #

  Widget build(BuildContext context) {
    return new PreloadPageView.builder(
      itemCount: ...,
      itemBuilder: ...,
      onPageChanged: (int position) {...},
      preloadPagesCount: 3,
      controller: PreloadPageController(),


  • Add 1 page pre-load function for PreloadPageView


  • Add an example to library


  • Add preloadPagesCount for preload multiple pages


  • Bug fix
