How did Heraclitus influence Plato's Cratylus dialogue?

In Plato's dialogue Cratylus, characters debate whether names are conventional or natural, reflecting a deeper inquiry into the nature of language. Aristotle notes that Cratylus introduced Plato to the teachings of Heraclitus, who viewed the world as constantly in flux.
