3 years ago @yulkin2002 Thanks for the code sample. I tried it and do get an error while passing a function as a dynamic object to logEvent(). But in order to pass DateTime.now(), since it accepts a string, you'll need to convert it into a string first and then pass it. So you can do below which should work:
await widget.analytics.logEvent(
name: 'test_event',
parameters: {'time': DateTime.now().toUtc().toIso8601String()}
);Closing this as not an issue. Above implementation should help you to answer and get rid of the exception. If you disagree, write in comments and I'll reopen it.

3 years ago thank you, it works. It would be great if you could add this to documentation as right now there is no way of knowing that I need to pass a string instead of an Object for DateTime.
Bug report
Describe the bug I am trying to log a timestamp as a custom parameter with firebase analytics plugin, but whenever I call the logEvent method on it, I get an exception. This custom parameter also does not appear in my dashboard.
Steps to reproduce
Steps to reproduce the behavior:
await analytics.logEvent( name: 'talentListLoadStarted', parameters: {'time': DateTime.now()}, );error log
``` `E/flutter (26632): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: Invalid argument: Instance of 'DateTime' E/flutter (26632): #0 StandardMessageCodec.writeValue (package:flutter/src/services/message_codecs.dart:419:7) E/flutter (26632): #1 StandardMessageCodec.writeValue.Expected behavior
parameter is logged and appears in my Firebase Analytics dashboard
Sample project
