Unhandled Exception: InternalLinkedHashMap' is not a subtype of type 'List

Question

I am trying to get the JSON response from the server and output it to the console.

Future login() async {
    var response = await http.get(
            


        

Answer 1

You can get this error if you are using retrofit.dart and declare the wrong return type for your annotated methods:

@GET("/search")
Future> getResults(); 
// wrong! search results contains a List but the actual type returned by that endpoint is SearchResults 

vs

@GET("/search")
Future getResults(); 
// correct for this endpoint - SearchResults is a composite with field for the list of the actual results
