State machine is basic requirnment when developing workflow in sharepoint. it would be great addittion to have it on flow if it has to be popular first choice for users.. i think flow developer must immediatly include them in their furture release.
Please respond if you need any understanding on this. I see great potential in flow, even replacing nintex workflow.
You can accomplish this today with switch inside a do-until and a variable. You just switch on the variable and do-until whatever the terminal state of the machin is. Inside each branch you set the variable to whatever the next state is. However, we understand that it would be easier with a first-classed shape. Thanks!
