Flutter - adding dependency to a package does not resolve dependency issue during the app compilation

I have just created my first flutter package. It has just dart code, so it is quite basic. However, I use one external dependency in my package to provider package. Since I don't use any of the provider classes outside the package, my understanding is, I should not need to add provider package dependency to the application, hence I might keep the dependency within my package only. When I try to compile the app, however, I get this error:

Error: Could not resolve the package 'provider' in 'package:provider/provider.dart'.
file:///local_path/lib/scale_widget.dart:5:8: Error: Not found: 'package:provider/provider.dart'
import 'package:provider/provider.dart';

Despite the fact, that provider package is imported inside my package. If I add provider dependency to my app, everything compiles.

You might need to run:

flutter pub add provider

Had same problem with path_provider package.

Error: Could not resolve the package ‘path_provider’ in ‘package:path_provider/path_provider.dart’.

Error: Not found: ‘package:path_provider/path_provider.dart’ import ‘package:path_provider/path_provider.dart’;

I was able to fix it by following commands:

1. flutter upgrade 
2. flutter pub cache repair
3. flutter clean && flutter pub get && flutter pub run build_runner build --delete-conflicting-outputs

Probably the problem was fixed already by flutter upgrade but i want to leave all the steps i did just in case. Ps. In my case this was update from Flutter 2.0.6 to 2.2.1 .

Stop your application and Run it again. Also, make sure that you'd inserted your provider in dependencies and not in dev_dependencies

Try running Pub get after adding the dependency, then stop your app and run it again instead of using Hot Restart. This worked for me anyway.

Make sure the dependencies are under "dependencies:" and not "dev_dependencies:" in your custom package pubspec.yaml
