Preload images in Flutter

I needed to load some images before showing them. Because sometimes I see some images loading slowly, and it bothers me.

In Flutter, we have precacheImage functions to load images into the image cache. You need to provide an image provider and build context. You can call this function wherever you want. I load my images in the builder parameter of the MaterialApp widget, and it works perfectly.

We should be careful about using this function. We don’t want to fill the cache completely. Therefore, we need to load only the necessary images.
