Hi Jeff Davies! I just replied to your Stack Overflow question (I was biking in San Francisco yesterday. It was awesome lol) here https://stackoverflow.com/questions/59471323/cannot-press-buttons-in-my-flutter-app-until-i-press-the-debug-button-in-dart-de/59493287#59493287. In short, I believe it’s not really caused by the debugger, but rather the debugger accidentally fixed a bug in the code. I posted a suggested fix in my answer. Hope it helps!
