Morphology

quick + as + a + flash

This is a simple simile: 'quick' combined with the comparative frame 'as a' and 'flash' (an instant) yields the meaning 'as quick as an instant' or very fast. A B1 learner who knows 'quick', the comparative pattern 'as a', and 'flash' (a very short period) can transparently infer the idiom's meaning; the construction is common across languages.

Etymology

The idiom quick as a flash compares quick action to a sudden bright flash of light, like lightning or a camera flash that happens in an instant. So it means 'very quickly'.
