cc @cbracken Can you look at this?

[cbracken]

Happy to!

[cbracken]

Narrowing down the scope a bit: Running an app that doesn't rely on networking should work fine -- i.e., there doesn't appear to be anything inherent to Flutter development/debugging that breaks when aeroplane mode is enabled. I'm able to do hot-reload development on a basic hello-world app with no issues.

In this case, it looks like there may be an unhandled network error from Firebase on the native side:

I'm assuming you're using the Firebase plugin? I'll see if I can wire it up and get a repro.

@cbracken yeah, here are our plugins from pubspec.yaml

dependencies:
  flutter:
    sdk: flutter
  path_provider: "^0.2.1+1"
  fluro: "^1.1.0"
  firebase_analytics: "^0.0.2"
  firebase_database: "^0.0.6"
  url_launcher: "^0.4.2+1"

[eseidelGoogle]

@collinjackson can you drive this to completion?

[collinjackson]

Yes, I'd be happy to investigate. Thanks for filing this.
