first check this article : https://flutter.dev/docs/development/data-and-backend/json and make sure of all steps : 1- add dependencies in pubspec.yaml 2- flutter pub get 3- flutter pub upgrade 4- flutter pub run build_runner build
after all, consider that:
part 'timeline.g.dart';
most be your file name which classes are in!
if your file name is difference with your class name, you should use your file name.
Had the same problem. Fixed it following these steps:
$ flutter pub get
$ flutter pub upgrade
$ flutter pub run build_runner build --delete-conflicting-outputs
Check have you created a constructor for class with no default parameters. Basically automated file is generated but error happens because it can not find a contractor for model
flutter pub run build_runner build
Just run the above command in the console. Everything will be fine
