I don't think that primary is required, or should I add it as well or write a manual comment instead of using the template?
Also will add tests for scroll_controller scrolling.
Thanks.

Hey @amanv8060! Thanks for the contribution.

I think adding primary as well here will be beneficial to the goal the issue is describing. It is the PrimaryScrollController (PSC) that the default keyboard shortcuts check to see if they can activate any scrolling actions, so both controller and primary sound like reasonable additions here.

Fun fact, in #99547, the PSC does not kick in automatically because the PSC only automatically attaches to vertical scroll views. 😉

Let me know if you need guidance for adding tests. Thanks!

Sure, will try to do it this weekend.

@Piinks I have added the tests for

if psc gets attached
if we can scroll the data table through controller

packages/flutter/test/material/paginated_data_table_test.dart

packages/flutter/lib/src/material/paginated_data_table.dart

packages/flutter/test/material/paginated_data_table_test.dart

packages/flutter/test/material/paginated_data_table_test.dart

This does not actually verify which scrollable used the scroll controller, like the other test below.

Since we never pass the controller to the second scrollable(footer), can we safely assume that it is always DataTable that uses the provided ScrollController?

That is a great question! I imagine it is possible the user may want access to one controller or the other at some point. Does the issue specify which scrollable is needed for access? If so, it may require we have clearer parameters here that indicate which controller this is.

Issue mentions that it needs controller for contents of PaginatedDataTable. I assume that it is for main content.

Hi @Piinks, Should I expose both the controllers?

I am not sure, if the issue is not clear we should ask the person that filed it for clarity. We shouldn't assume t know what they mean. Can you ask in the issue you are trying to resolve?

Sure, I did ask and the author only needs the controller for DataTable.

LGTM! Thank you!

This will need a second review, I have sought one out.
