Dependency on an initialized instance of a MojoShell on the embedder breaks iOS

[sethladd]

Just tried the latest game with the latest flutter engine. Got this error right after the game attempted to start. All I see on my ipod touch is a white screen.

~/Code/game[master] $ flutter --version
Flutter from git@github.com:flutter/flutter.git (on master)
flutter revision: 3094348ad436fa4b7323a8afb4022867ad7fbe62 (37 minutes ago)

What does flutter logs say right before it crashes?

I'm running the game via xcode with the "play" button. Where can I see the logs? Or, should I also run flutter logs right after I press "play" ?

Would be useful if we had flutter version or some command dump more information about the attached devices. @devoncarew. In this case, I'm asking myself what version of iPod Touch this is, and is it 32-bit, for example. Filed #1519

I wonder if we should distribute Debug versions of the engine. It should be trivial to do that (particularly on our sparkely-new, totally-vaporware-but-definitely-not-overhyped infrastructure. :p) from a bot perspective, would just require some plumbing on the flutter tool side.

I will stop stripping the release the binary so we can get better stack traces for now

This was an engine/mojo issue, yes? From another email:

"The recent Mojo SDK roll seems to have added a dependency on an initialized instance of a MojoShell on the embedder. The MojoShell is only available on Android."

[chinmaygarde]

Yes. I am investigating this now

Fixed in https://github.com/flutter/game/pull/49
