It looks like your .dart_tool/.package_config file was written incorrectly. It will probably be fixed by rewriting it. Use the menu Tools > Flutter > Flutter Pub Get. Does that fix it?

Without additional information we're not able to resolve this issue, so it will be closed at this time. You're still free to add more info and respond to any questions above, though. We'll reopen the case if you do. Thanks for your contribution!
