颤抖，位置参数过多（但事实并非如此）

Question

I've declared a static method in the class API with one required argument "token". But in Android Studio i get an error

" error: Too many positional arguments: 0 expected, but 1 found. (extra_positional_arguments at [disconnection] lib/main.dart:28) "

but if I run the code the method works fine, the argument is received.

If I remove the argument "TEST-ARG" the error disappear, but i get an error "Too few positional arguments" error in the app ( red screen ).

but if i remove the argument "TEST-ARG" i get an error

checkUser(){
    API.checkUser("TEST-ARG").then((response){
      print(response.body);
      setState(() {
        loginCheck = false;
      });
    });
}

API dart

class API {
  ....
  static Future checkUser(String token) {
  }
  ....
}

what am i doing wrong? Thanks

It was a Android Studio issue. I've deleted and recreated api.dart, quit and reopen Android Studio and issue is gone
