flutter start doesn't give good error messages when it can't find main.dart #53
Description
When I try to flutter start any of the example programs widgets, fitness or rendering I get an error like the following:
Downloading Sky Snapshot from the cloud, one moment please...
Downloading Sky Shell from the cloud, one moment please...
[1108/213053:FATAL:loader.cc(21)] Check failed: base::ReadFileToString(path, &source). /home/dmta/flutter/flutter/examples/rendering/./lib/main.dart
The other examples I have tried worked fine.

There isn't a "lib/main.dart" in the rendering examples. Instead, you need to use the
-toption to specify which one you want to run:Assuming that works for you, we should improve the error message you get so that it's obvious what's happening.

Yes, now that you say it, it makes sense. But reading the error message I originally thought that something must be wrong with the
ReadFileToStringfunction... I wouldn't have thought of a missing file...abarth commentedon Nov 9, 2015
Yeah, we should improve the messages in two ways:
fluttercommand should check whether the target exists and print a useful message if it doesn't.Improve error handling in sky_snapshoter
Improve hit testing
Strip symbols of clang_x86 binaries (flutter#53)
