Can't generate files when using a local library or dependency_overrides

[FDuhen]

Hey,
I created a project to test the library and whenever I'm importing a local library in my test project (either by having a reference to it or using the dependency_overrides method), I do have the following error.

The pubspec.yaml file has changed since the pubspec.lock file was generated, please run "pub get" again.
pub finished with exit code 65

Here is the how to reproduce this issue.

1. Clone any library, font_awesome_flutter for example
2. Create a new project with a version of Flutter 2.0.3 or 2.0.4
3. Implement the library font_awesome_flutter in the pubspec.yaml with the relative path to the previously cloned folder
4. Import the build_runner and flutter_gen libs
5. Run flutter pub get and flutter pub run build_runner build --delete-conflicting-outputs

pubspec.yaml

version: 1.0.0+1

environment:
  sdk: ">=2.12.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  font_awesome_flutter:
    path: ../font_awesome_flutter/

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
#  cupertino_icons: ^1.0.2

dev_dependencies:
  flutter_test:
    sdk: flutter
  build_runner:
  flutter_gen:

And here is my flutter doctor -v

If I do the same thing but targeting the published package of font_awesome_flutter instead of the local one, no problem.
I may have missed a crucial information !
Thank you

Hi @FDuhen

Could you try again using flutter_gen_runner instead of flutter_gen?
In the recent release, we rename the package name for using with build_runner.

Thanks a bunch ! Looks like it's working as expected !
