   Without additional information, we are unfortunately not sure how to
   resolve this issue. We are therefore reluctantly going to close this
   bug for now.

   If you find this problem please file a new issue with the same description,
   what happens, logs and the output of 'flutter doctor -v'. All system setups
   can be slightly different so it's always better to open new issues and reference
   the related ones.
