If the app crashes on startup, the output is poor:

    Leaving in current milestone since it's a tool crash that might affect many users.

    Is this still reproducible?
    Now when application crashes on the start(I forced null pointer dereference into the engine to force the crash), it sits waiting for the response from observatory:

    ~/$FH/flutter/examples/flutter_gallery  ‹master*› 
╰─➤  $FH/flutter/bin/flutter run --local-engine android_debug_unopt_x86                                                       130 ↵
...
[        ] Waiting for observatory port to be available...
[+1045 ms] I/flutter (11772): [INFO:platform_view_android.cc(111)] Could not initialize Vulkan surface. Falling back to OpenGL.
[  +10 ms] I/flutter (11772): [INFO:platform_view_android.cc(115)] GL surface initialized.
[   +9 ms] I/FlutterActivityDelegate(11772): onResume setting current activity to this

    while on the device it says 'Unfortunately, Gallery has stopped'.

    What happens once the tool times out?

    (I think the original bug was about crashes in the framework, not the engine.)

    For me it never times out.

    Well, I guess that's not as bad as a crash... still not ideal though. :-/

    Closing(as obsolete) now that it there is no long stack trace.
