React-native-fast-image: Detect if image is in cache

[cmmartin]

Is there any way to detect if an image is in the cache?

My use case is that I want to do a progressive image loading effect when the image is not cached (fade in on load). However, I don't want the fade when the image is cached, because it is better to just show the image immediately in that case

This will be possible once https://github.com/DylanVann/react-native-fast-image/pull/228 is implemented

If you want to show up cached images immediately, and show loader on newly images, you can use a temporary hack until it will be improved:

InitialState: isLoading: false

onProgress //set isLoading to true
onLoadEnd //set isLoading to false
