Cannot control the cache size!

I am using _cached_network_image: ^3.2.0_ to cache some images that I have stored in firebase storage.
Each image is around 2MB, and I have 24MB images in total. I want to cache them all for less than 10MB. Is it possible to achieve this using cached_network_image package?
By changing the parameters like `maxHeightDiskCache` or `memCacheHeight` the total cache size is still around 24MB.
Here is how I use it :

```
CachedNetworkImage(
// maxHeightDiskCache: 200,
// maxWidthDiskCache: 200,
memCacheHeight: 200,
memCacheWidth: 200,
height: 200,
width: 200,
imageUrl: data,
),
```

BTW, I have tried
```
Image.network(
data,
cacheHeight: 300,
),
```
and the total cache size will be a few KB. So, I assume that the issue is not coming from the other parts of the code.
