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

Currently it's only support preload one page, will enhance it latter if people need preload multiple pages.

Usage

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

Example

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