What if address is not an object it is an array how can we reach it?
Objects can be reached by user.address.zipcode
Array could be reacht as user.address[index]['zipcode'] ??

[@MobileProgrammer]

That’s right

[@bugracakirr]

But i can not reach the index from user_list_row.dart

[@MobileProgrammer]

Are you getting any errors?

[@bugracakirr]

@@MobileProgrammer I got two errors first one is Error: Operator '[]' cannot be called on 'List?' because it is potentially null.

[@bugracakirr]

@@MobileProgrammer Second one is : Error: The operator '[]' isn't defined for the class 'Price'. I can not use [ ].
