Issue 1:
Steps to Reproduce

Seemingly out of nowhere, my app started crashing on startup. Initially I thought it might be due to recent changes, so I backed out to a prior build that I knew to be working. That also failed. So I tried with a brand new project:

flutter create repro

cd repro

flutter run

That also fails.

Note that the same app built via flutter build apk does work when I deploy it to my device.

I've tried:

flutter clean

restarting my machine

plugging/unplugging my device

None of these things worked, but switching channels to alpha did. So I assume this has to do with the fact that I upgraded flutter earlier this morning and master is currently broken? Super weird that it didn't trigger any problem for hours after the upgrade.
