I use the following code in my Flutter app / Dart:
Amplitude.getInstance().setUserId(userID, startNewSession: false);
Amplitude.getInstance().logEvent(actionName,
eventProperties: {
'pageName': pageName
}
);
When I check the Event Stream, I see the pageName property as an Event Property.
But when I attempt to create a chart to GroupBy page Name for a given actionName...I don’t have that option.
