Something to do with plugins?

This appears to be a Windows-specific path handling problem (it errors in _createPluginClassName (package:flutter_tools/src/commands/create.dart:242), but the underlying problem is that the name argument passed to that function should have been a folder name, but it's actually passed an empty string. So this is an error in flutter tools.

You can work around this by passing flutter create a folder name rather than passing it just .

My suggested fix for this would be to limit the arguments accepted by flutter create to only be legal dart package names. That would also fix #9564.

[sethladd]

works for me

Actually, I take that back, the real problem is a bug in package:path: dart-lang/core#507
