HttpResponseCache | HttpResponseCache library provides transparent | HTTP library

I have the method below to request pages from wiktionary.org, the problem is that the server is returning Cache-control => private, must-revalidate, max-age=0 in the headers, which is preventing HttpsURLConnection from storing the requests.

Is there a way to force then caching of those pages?

When I add Google sign in or firebase dependencies in my yaml file, the app crashes. It crashes in iOS and does not build in Android.

I updated my flutter, I added the required line in the build.gradle file. The example memechat doesn't even run. In the example app that's created by default, it works before I add the dependencies and works once I take them out.

When I don't have "google_sign_in: ^0.2.1" in my yaml file, it works fine. When I add it, it doesn't build and I get the output below about "Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'."

If it add these firebase dependencies and take out the google-signin on, it doesn't work either and I can see a similar output. firebase_analytics: ^0.0.2
firebase_auth: ^0.0.2
firebase_database: ^0.0.4
firebase_storage: ^0.0.2

Has anyone run into something similar?

Initially the objective was to use both disk and memory cache. This would require implementing LRU cache and DiskLruCache. However, since HTTPResponse cache uses disk space, I chose to use LRU cache and do con.setUseCaches(true);

The problem is that I don't really understand what gets implemented first. For LRU and DiskLru cache, this is the algorithm:

i.e.

first check memory cache for an image

if there is an image, return it and update caches

else check disk cache

if disk cache has an image, return it and update caches

else download image from the internet, return it and update caches

Now with the code below:
