Hi @officialkhairi ,

Thanks for reporting this issue. We’ve attempted to reproduce it on our end but haven't been successful so far. That said, the error you shared appears to originate from the this line in the code: plugin_firebase.dart#L205

Specifically, the method castParameterType(properties) relies on Dart’s inferred types and may throw an error if properties is not exactly of type Map<String, Object?>.

To help us troubleshoot further, could you please provide the following details?

1. The version of segment_analytics you're using
2. The version of segment_analytics_plugin_firebase you're using
3. The actual type of the properties variable passed to castParameterType(properties) – is it typed as Map<String, Object?>, or something else?

Thanks.
