Hi there! You're right that for analysis, your data warehouse needs an experiment assignment table that show a user, experiment, date of exposure, and variation id. Learn more about experiment assignment queries. Depending on how you have GrowthBook set up, you need to ensure that the data is being tracked. This is done through your event tracker, which is usually configured to be fired through the
trackingCallback
in the GrowthBook SDK.

Hello! I work with Trey, we are using the Flutter SDK, we can fetch the feature flag values and they update properly, but when creating an experiment with the feature flag, the flutter sdk doesnt seem to return it, tried with at last 3 feature flags to confirm, because of that the tracking callback is never called. If you can take a look, I dont think experiments are working for the flutter sdk. Another thing, let me know if it is in the docs, are there specific name/properties of the event that we need to use to connect properly the datawarehouse table to growthbook?

@strong-mouse-55694 any thoughts on this? Thank you

Under Data Sources in the app, you can modify the Experiment Assignment Query to fit your data:
On the Flutter SDK, please ask the question in #C038XP683NC. I'm not aware of any current issues with the SDK, but please ask your question there, as they'll be able to provide better support/expertise.

@strong-mouse-55694 how does the experiment table schema get populated? When we try to connect segment/snowflake it says that the experiment table does not exist
s
You need to configure your SDK to fire a callback with Segment. https://docs.growthbook.io/event-trackers/segment#tag/VisualChangeset_model
