Hot reload and restart not working in iPad pro

[dark-chocolate]

Steps to Reproduce

Install the app using green play button in iPad pro. Once the app is installed, the flutter hot reload button is disappeared from Android Studio toolbar and pressing control + r reinstalls the app form the scratch by starting Xcode build.

Device

I am only having issues in iPad pro 2017 running 12.0.1, I have iPhone running same version 12.0.1 and it doesn't have any issue with hot reload and restart.

@dark-chocolate could you do flutter doctor -v and append that output here (with your iPad connected)?

@stevemessick I also added a screenshot when my app is running in iPad. There is no hot reload, just a play button to reinstall the app from scratch.

I don't know what happened (maybe an update in some plugin), but now it started working fine.
Here is the screenshot.

Once again the problem occurs. I don't know sometimes it works (10% of the time it seems to work).

Note: Only one device is up and running and there is just one process in the Run window.
