Below is the main.dart code. Getting error on generateRoute -> onGenerateRoute: router.generateRoute. Error is

The name 'generateRoute' is being referenced through the prefix 'router', but it isn't defined in any of the libraries imported using that prefix. (Documentation) Try correcting the prefix or importing the library that defines 'generateRoute'. Please help.

This is the router.dart file code

CodePudding user response：

There is a typo r will upper case as class name

     onGenerateRoute: Router.generateRoute,

As for the import section as prefix use case will be

import 'package:initsurvey/core/router.dart' as router;

   onGenerateRoute: route.Router.generateRoute,
