Fix StacklessClosedChannelException

✅ Solution

The "StacklessClosedChannelException" in firebase-auth often stems from prematurely closing or interrupting streams/channels used for communication, especially during asynchronous operations like network requests. To fix this, ensure proper management of resources by verifying that streams/channels are fully open before use and only closed after completion of all associated tasks, using try-finally blocks or appropriate stream handling mechanisms to guarantee closure even in error scenarios; also consider increasing timeouts.
