I’am trying to send a custom event according to this [documentation](https://docs.dynatrace.com/docs/observe/digital-experience/new-rum-experience/mobile-frontends/flutter/id-08-custom-events). This is my Flutter code to send the event:

```java
Dynatrace().sendEvent(
      EventData(
        eventProperties: {'event_properties.comment': review.value},
      ),
    );

```

I’ve already&nbsp;define the event properties “comment” in the Dynatrace web UI.

And this is the log from mi Flutter console:

```javascript
[2026-04-15 11:12:58][DYNATRACE][INFO][EventProcessor]: Reporting event: {"characteristics.is_api_reported":true,"event_properties.comment":"this is a test","duration":0,"start_time":1776262378974,"flutter.version":"3.35.2","dt.rum.event.source.type":"flutter","characteristics.has_event_properties":true}

```

However, when I run my app and send the event, I don’t see anything in the dashboard. “No events” is what I see.

I’m working with&nbsp;dynatrace\_flutter\_plugin v3.333.1.

Hey smamani,

The linked UI shows “events” from the root cause analysis like a [Mobile app slowdown](https://docs.dynatrace.com/docs/dynatrace-intelligence/root-cause-analysis/event-analysis-and-correlation/event-categories/slowdown-events#user-action-duration-degradation). It does not show data reported by OneAgent.

The sendEvent API is part of the New RUM Experience and this monitoring data will not be visible in the RUM Classic screens. You can see the event in the “Users & Sessions” app (you have to enable the “Property” category). And you can also query the event via DQL (in the Notebook app or as part of your dashboard).

Hi Thomas,

First of all, thank you for your quick response. I tried what you suggested, and now I can see the events!

Just one more question: is it possible to filter for this event across ALL sessions in my app from “User & Sessions”? I need a list of all events of this type.

You can use [DQL](https://docs.dynatrace.com/docs/platform/grail/dynatrace-query-language) in the “Notebooks” app. For example:

```java
fetch user.events
| filter exists(event_properties.comment)

```

This query will return the event for all sessions in the given time frame. You can fine-tune it based on your use case.
