Issue
How to fix this? The argument type ‘String?’ can’t be assigned to the parameter type ‘String’.
Solution
you just need to add !
at the end of each one of your variables, so Uri.base.queryPrameters['token']
becomes Uri.base.queryPrameters['token']!
of course this is assuming that your data is not null, otherwise it would give you a runtime error.
