firebase_cached_image's Issues

Questions about adding web caching

I was thinking of adding web caching to your plugin, but wanted to find out why this may not have been implemented already.

I was thinking of altering web_cache_manager.dart to convert the files to base64 for caching in sqflite, and decode from base64 for retrieval... or potentially just using a blob.

I was also thinking of using dart:indexed_db library for a more native web implementation according to this example, where video blobs are stored in the IndexedDB

Any thoughts on this? Web caching is important for my project. Just wanted to get any ideas or thoughts you may have already had before diving in.

Thanks!

Where it is cached

Hi everyone, i have a question

With this lib, these photo is cached when app is launched, and when app is kill, the cached is cleared
Or it is stilled cached although app is kill and just only clear if the clear code is called

Thanks

loadingBuilder support

Can't track image loading status because loadingBuilder doesn't return ImageChunkEvent

onError handling

Just implemented this to my project and getting great results so far. As a test I changed my url to be wrong and this causes an error of course. Is there a way to handle such an error with this package? If not what would be the best way to do so manually?

Thanks in advance

Support for firebase_storage 11.0.X

Because every version of firebase_cached_image depends on firebase_storage ^10.2.16 and depends on firebase_storage ^11.0.4, firebase_cached_image is forbidden.
So, because depends on firebase_cached_image ^0.3.1, version solving failed.

The method 'preCache' isn't defined

I got The method 'preCache' isn't defined for the type 'FirebaseCacheManager'

await FirebaseCacheManager().preCache(
          FirebaseUrl("gs://bucket_f233/profile_pic.jpg"),
);

Versions are as follows
firebase_cached_image : 0.4.2
Flutter 3.0.1 • channel unknown • unknown source
Tools • Dart 2.17.1 • DevTools 2.12.2

Unexpected behaviour by Source.cacheServer.

In our app we encountered an issue where a video stored on Firebase Storage would not play if it wasn't already cached locally. Instead of fetching and playing the video from the server, the app would display a black screen and log a "file not found" exception.

Here are the error logs for reference:

To address this problem, we implemented a manual check to determine whether the video was already cached. If it was not found in the cache, we would explicitly set the source to Source.server. Conversely, if the video was cached, we used Source.cacheServer. This solution successfully resolved the playback issue.
