Help: nullable parameters for Flow triggered in PowerApps?

[Meneghino]

I am trying to build a flow triggered in PowerApps, but need nullable parameters and cannot seem to make it work.

Has anyone managed?  Very grateful for any help.

Hi Meneghino,

I guess your flow could be triggered by a Button. Create a simple flow which is triggered by a Button.

On the app, add the flow on the button. Then when the button is clicked, though the title field is null, it can also be saved to the data source.

Hope this could be a reference for you. If I misunderstand your scenario, please feel free reply.

Best regards,
