Inconsistent Stream Behavior on Internet Disconnect Between Android and iOS

[memishood]

Describe the bug
I am using the supabase_flutter and listening for user changes from the users table. When the internet connection is lost on Android, the stream throws the following error:

RealtimeSubscribeException(status: RealtimeSubscribeStatus.channelError, details: RealtimeCloseEvent(code: 1002, reason: ))

However, when the internet connection is lost on iOS devices, no error is thrown, and no event is emitted. This results in inconsistent behavior between platforms, making it difficult to maintain accurate and synchronized results.

To Reproduce
Steps to reproduce the behavior:

1. Listen any supabase table changes in the flutter app
2. Disconnect the internet on an Android device and observe the error.
3. Disconnect the internet on an iOS device and observe the lack of any response or error.

Expected behavior
On both Android and iOS, the stream should behave the same way when the internet connection is lost to ensure consistent behavior across platforms.

I have encountered this issue too. I am not sure why it happened in my case, but got the reason as RPC Call Error, does anyone knows why it happened, I tried it on android API level 32 and above

Something similar is happening to me too.

When I launch my production web app from the Flutter CLI, no error is thrown when I turn off the internet. I still get real-time updates after I turn the internet back on (As I would expect).

However, when I open the production web app from the browser, the UI indicates an error and no longer receives updates after the internet connection is reestablished.
