The methods _handleButtonPress
and _publish
are tightly coupled with UI operations. Consider using a more decoupled approach for error handling and business logic.

Tip
Codebase Verification
Ensure proper error handling in asynchronous operations.
The inspection of the surrounding code for await
statements in lib/screens/mobile/mobile_home.dart
and lib/screens/mobile/router_dialogbox.dart
reveals that some asynchronous operations are already wrapped in try
and catch
blocks, ensuring proper error handling. However, there are instances where await
statements are not enclosed in error handling constructs.
Instances without proper error handling:
lib/screens/mobile/mobile_home.dart
await _showRouterDialog(context, routerResult, scaffoldMessenger);
await _showCloseRouterDialog(context, routerProvider, routerResult);
await showDialog(...)
await session.publish(...)
await session?.unregister(reg);
await session?.unsubscribe(sub);
await session.register(...)
await session.subscribe(...)
await session.call(...)
Instances with proper error handling:
lib/screens/mobile/mobile_home.dart
await action();
(wrapped intry
andcatch
)await connect(...)
(wrapped intry
andcatch
)
lib/screens/mobile/router_dialogbox.dart
await Navigator.pushReplacement(...)
(wrapped intry
andcatch
)
Recommendations:
- Wrap all asynchronous operations in
try
andcatch
blocks to ensure proper error handling. - Review the identified instances and add error handling where missing.
Code Locations:
lib/screens/mobile/mobile_home.dart
lib/screens/mobile/router_dialogbox.dart

Seems like the humans are having a chat. I'll hop back into my burrow for now. If you need me again, just tag @coderabbitai in a new comment, and I'll come hopping out!
