PR Code Suggestions ✨

Category	Suggestion	Score
Possible bug	Ensure BitArray has a toJson method to prevent runtime errors Ensure that the BitArray class has a toJson method implemented. If BitArray does not have a toJson method, this line will cause a runtime error when it is called. If the method is not implemented, consider adding a toJson method in the BitArray class or handling the serialization differently here. packages/substrate_metadata/lib/utils/to_json.dart [41] } else if (value is BitArray) { - return value.toJson(); + return value.toJson(); // Ensure `BitArray` has this method Suggestion importance[1-10]: 9 Why: The suggestion correctly identifies a potential runtime error if the BitArray class does not implement a toJson method. Ensuring this method exists is crucial for the code to function correctly, making this a high-priority suggestion.	9
