Which part of adobe flash does not work through a proxy do you think ?
If you download a simple object or watch a movie it will use the browser proxy for that!
I am not 100% sure if there are no backdoors that would allow flash to directly call out, I know of no such thing.
Can you go a bit more into details ?

Yeah, there is, flash can go very low for network connections. Look at hulu player for example, you can be using browser proxy but it still knows if you're not US based
