Issue 1:
Unfortunately, it's not clear what action I can take, as a developer. Can we give more guidance about what I should do now?

I'm trying to run the gallery app on my iPad, and I got this:

~/Code/flutter/examples/material_gallery[master*] $ flutter -d ipad run

Issue 2:
Can we suggest to the user what to do to recover from this error? I'm not sure what to do now. Thanks for any tips!
