Type conversion error in lib/Graph.dart #60

Hello. I tried using this package on flutter 2.2.3. I am getting this error "A value of type 'dynamic' can't be returned from the function 'hashCode' because it has a return type of 'int'.dart(return_of_invalid_type)" on line 210 of lib/Graph.dart. @override int?? get hashCode => key?.hashCode ?? Object.hash(source, destination); Not sure how to fix this. Thanks for all the work for creating this package on flutter, exactly what I was looking for!

You might have to update flutter version.
