Line 43 in 90afc0e

final conversationProvider = Provider.of<ConversationProvider>(context, listen: false);

here the provider was accessed inside a post-frame async callback. During that time, the widget was still mounted but its Provider was no longer in the widget tree, so the provider lookup returned null

Code Review

This pull request introduces if (!mounted) return; checks within the initState method's addPostFrameCallback in ConversationsPage. These additions are crucial for preventing potential runtime errors that can occur when asynchronous operations complete after the widget has been disposed, leading to attempts to access a stale BuildContext or call setState on a disposed widget. This is a good practice for ensuring the stability and correctness of the application.

Adding if (!mounted) return; here is a critical improvement. In asynchronous initState callbacks, especially after await calls, the widget might be disposed before the callback resumes. Accessing context or calling setState when mounted is false can lead to runtime errors or crashes. This check correctly guards against such scenarios.

This second if (!mounted) return; check is also important. Even if the first await call completes successfully, the widget could still be unmounted before the subsequent Provider.of call for folderProvider. Placing this check ensures that context is only accessed if the widget is still active in the widget tree, preventing potential BuildContext related errors.
