Does anyone know how to create a pop-up window in Power apps that depend on a power automate flow?

If I try to save a photo in sharepoint from Power apps with a name that already exist, I want a pop-up window to be shown:

"A file with that name already exist, do you want to continue?" 🙂

This can be accomplished by combining a few approaches. You will want to present the user with a blocking/modal dialog, while the Flow runs and then returns a value.


Thankfully, Flows are synchronous when invoked from a canvas app. At a high-level, you will

  1. Create a new Flow from the PowerApp
  2. In the Flow, develop your logic for creating the photo (presumably from canvas app?)
  3. Determine the outcome of the SharePoint action (good, or bad)
  4. Pass back the result (maybe a Boolean [true/false]) to the canvas app
    1. If good, show a positive result and maybe close the dialog
    2. If bad, show a negative result and then prompt user



@rahulswimmer has a cool write up on elegant notifications for users. BTW

@GarethPrisk Thank you for your answer.
I already have a Powerapp and a flow that works. I even have a pop-up, but I can't figure out the formula to put in the pop-up that stop the flow if the same name already exist.
