If the issue is communication with real iPhone, I guess this is because port forward.
We're improving the logic like appium/appium-xcuitest-driver#1066
I guess you need to establish a connection to 54061 on the real device from this driver.

Probably flutter uses iproxy to achieve it. https://github.com/flutter/flutter/search?q=iproxy&unscoped_q=iproxy
(Appium replaced from iproxy to our own implementation for the usage)

Error: Couldn't start port forwarding on port 8202. Please provide a different port using 'wdaLocalPort' capability

Didn't get any flutter related error.
Please use the available port in wdaLocalPort capability.
