Huge cache using AssetEntity

[rignaneseleo]

I'm using ImageItem to display a list of AssetEntity.
I noticed that on Android after scrolling many pictures (around 2000), the cache of the app itself is huge like 10-12 GB.

How is it possible? The size seems too big to be full of thumbnails, it looks like storing and moving al the pictures with no compression.

What is the logic behind:
ImageLruCache.setData(widget.entity, widget.size, data);
or
await widget.entity.thumbDataWithSize(widget.size, widget.size); ?

EDIT: After many tests, I can say that this problem occurs only on ANDROID 10.

Thanks
