Flutter tutorial is broken

[alexrecarey]

Hi team, thank you for the wonderful reasource that is learn-graphql.

It seems the flutter tutorial needs to be updated. On a fresh clone of the repo, with the latest version of dart, trying to run the app-final folder gives me the following output:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Thanks again.

It is not only that... A lot of the code in there are now nonsense. This may have been working for old flutter versions but now null safety is a must and the code doesn't have anything for null safety. Also the old initialization code is now obsolete. It should be updated for graphql_flutter:5.1 at least. Current code still uses graphql_flutter:3.0.1

Trying to fix this code to understand how entire thing works is a PITA.

Though I think nobody checks here, so I don't think a fix will be here soon enough for me.
