PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Duplicate Error Handling The DisableBluetooth method calls both result(FlutterError) and result(false) when Bluetooth is not available, which could cause issues with multiple responses being sent Error Handling The disableBluetooth method should handle the case where adapter.setPowered(false) succeeds but adapter.powered is still true, which could indicate a failure to disable UI State Handling The Bluetooth enable/disable button state may not update immediately after the action completes since it depends on bleAvailabilityState which may have a delay in updating

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Remove redundant result callback after error handling to prevent multiple responses Remove the redundant result(false) call after result(FlutterError(...)). The function should return after sending an error to avoid sending multiple responses. windows/src/universal_ble_plugin.cpp [94-98] if (!bluetoothRadio) { result(FlutterError("Bluetooth is not available")); - result(false); return; } Apply this suggestion Suggestion importance[1-10]: 9 Why: Calling result() twice can lead to serious issues as the callback should only be invoked once. The second call could crash the application or cause undefined behavior.	9
General	Use proper Exception objects instead of string literals for error handling Use throw Exception(...) instead of throwing a string literal to follow Effective Dart guidelines for error handling. lib/src/universal_ble_linux/universal_ble_linux.dart [61-62] if (adapter == null) { - throw "Adapter not available"; + throw Exception('Adapter not available'); } Apply this suggestion Suggestion importance[1-10]: 5 Why: Using proper Exception objects instead of string literals is a Dart best practice that provides better error handling and debugging capabilities, though the current code would still function.	5
