Are mindfulness and flow related

Loose definitions for mindfulness and flow (text from Wikipedia): *Mindfulness* involves being aware moment-to-moment, of one’s subjective conscious experience from a first-person perspective. *Flow* is described as a deep focus on nothing but the activity – not even oneself or one's emotions. Both are good, but they appear to be opposite mental states. Is entering a flow state incompatible with developing mindfulness? If so, then would flow be considered "bad"? If not, then how can these distinct concepts be presented so that they are compatible?
