pubspec.yaml: dependencis: ....... responsive_builder: ^0.1.5

console print error: Unable to find modules for some sources, this is usually the result of either a bad import, a missing dependency in a package (or possibly a dev_dependency needs to move to a real dependency), or a build failure (if importing a generated file).

Please check the following imports:

import 'package:responsive_builder/responsive_builder.dart'; from web_router_demo|lib/widgets/navigation_bar/navigation_bar.dart at 2:1

Update the package to the latest 0.1.9,

• run flutter pub outdated, see what's out of date. Update those.
• run flutter clean
• flutter pub get
• try again.
