progressTracker

open val progressTracker: ProgressTracker
Overrides FlowLogic.progressTracker

Override this to provide a ProgressTracker. If one is provided and stepped, the framework will do something helpful with the progress reports. If this flow is invoked as a sub-flow of another, then the tracker will be made a child of the current step in the parent. If its null, this flow doesnt track progress.

Note that this has to return a tracker before the flow is invoked. You cant change your mind half way through.
