Maybe Venus flytrap’s centre put on flat surface (6)
I believe the answer is:
planet
'maybe venus' is the definition.
(Venus is an example)
'flytrap's centre put on flat surface' is the wordplay.
'centre' indicates the central letters.
'put on' is a charade indicator (letters next to each other) (some letters go on or after others).
'flat surface' becomes 'plane' (I've seen this in another clue).
The middle letter of 'flytrap' is 't'.
't' after 'plane' is 'PLANET'.
(Other definitions for planet that I've seen before include "Jupiter is one" , "massive revolver" , "Is Pluto one?" , "body in orbit" , "Celestial body orbiting round a star" .)
