Solution:

It looks like the error you’re encountering is due to a type mismatch between the return type of your getDoctors function and the expected return type when setting the doctors state. You’re trying to set a list (List) to the doctors state, but the function is declared to return a Future.

To resolve this issue, you should update your getDoctors function to return a List instead of a Future. Here’s the modified code:

Your code ought to function as intended after this modification, which should fix the type mismatch problem. The obtained information is now assigned directly to the doctor’s list within the setState function, and the getDoctors function now returns a FutureVoid.
