How can I preload next image? #492

Open niuhuan opened 2 years ago

niuhuan commented 2 years ago

I make a on line gallery with photo_view, and implement loading builder.

My imageProvider can download image and cache to local.

I tried download image to cache early, but photo_view display loading widget before scroll over.

Can I preload next 2 image and previous 1 image ?

Like these code

PhotoViewGallery.build(
preloadNext: 2,
preloadPrevious: 1,
);

you can use precacheImage, which is what I use in my app.
