This might be a bug.

The Dart team would greatly appreciate it if you would take a moment to report this problem at http://dartbug.com/new.
If you are comfortable with it, it would improve the chances of fixing any bug if you included the file /var/folders/fl/37mw9mm95n589pswk4dr5twc0000gn/T/initialize_from.dill5Eb7FA/initialize_from.dill.gz in your error report, but be aware that this file includes your source code.
Either way, you should probably delete the file so it doesn't use unnecessary disk space.

Thank you for taking the time to report this issue!

Three things happens here:

• Error: Error when reading '../../Library/Mobile%20Documents/com~apple~CloudDocs/flutter/flutter/bin/cache/artifacts/engine/common/flutter_patched_sdk/platform_strong.dill': No such file or directory
• It cannot initialize from the previous dill
• It cannot compile

All of these are caused by not getting the sdk.
First, the sdk file it's been told to read doesn't exist.
Second no component is created because no sdk is loaded (because it couldn't read the file). We should probably catch situations like that.
Third we cannot actually compile anything because we have no sdk.

Why there is no sdk I don't know --- possibly it was accidentally deleted? Or maybe there was an unzipping error or something..? (I don't know whether the flutter tools catch stuff like that) (or is it located on some cloud drive that hasn't synced yet? (com~apple~CloudDocs seems to have something to do with iCloud Drive when I search for it).

/cc @jonahwilliams who might know of other situations where the sdk has disappeared..?

[jonahwilliams]

Yeah, this seems like a case where bin/cache is corrupted that we need to recover from (fyi @christopherfujino who is looking at making this more robust)

[christopherfujino]

Yes, this issue should be moved to github.com/flutter/flutter. Does a dart-lang/sdk have to do that @jensjoha? I don't see anything in the UI to move the issue.

[jensjoha]

Hmmm --- I don't seem to be able to move it to flutter either... (Maybe I just don't know how).

[mraleph]

You can't move issues between organizations AFAIK. So somebody just needs to move it by hand.
