When you create a solution with an PowerApps app and you want to connect your App with a Flow you might run into a small problem when you try to add a Flow to your Canvas based PowerApp. It is nice when the products that are part of the Power Platform work nicely together. In this case it may be slightly harder to find the right way of doing things.
I’m starting by creating a new solution.
Now you can add your app and a button in your app. And then when you try to add a flow there is no Flow option!
To make it all work, save the App and give it a name.
Then use the publish all customizations to make sure that all your changes in the app are available.
And now when you open your app again there is an option to attach your flows to your button.
