fix: ./pubspec_overrides.yaml generated with \ on windows breaks docker build.

[djkingCanada]

I'm on windows (.net legacy projects, sigh) and have a shared module between my server and client using the path option. The build tool generates a ./pubspec_overrides.yaml using '' in the path.

'' is the platform separator so I suspect this is coming from code that is trying to be platform independent. The problem is this breaks the docker build as a path with \ is not a valid Linux path.

I'm thinking this could be an issue on mac with ':' being the system separator (I haven't tested this). Maybe we need a way to specify the target separator for the process?

I'm willing to help with this if someone could give me a place to start looking.

Hi @djkingCanada! Thanks for submitting an issue.

I would like to reproduce the issue. Can you provide an enumerated list of steps to reproduce this issue?

As a guess, this is probably related to the bundling process, you might want to take a look at the dart_frog_prod brick, see:

dart_frog/bricks/dart_frog_prod_server/hooks/pre_gen.dart

Line 88 in b990068

final externalDependencies = await createExternalPackagesFolder(

@alestiago: All I did was run the build on a windows machine, that produces a docker file with \ used in the file paths and then when you try to use that docker file to build a Linux image things break.

I have the same issue.

to reproduce the issue:

• use a local lib like this :

 shared:
       path: ../server/packages/shared

• build : dart_frog build (on Windows) => this will generate pubspec_overrides.yaml file in the build directory.
  that contains :

dependency_overrides:
  shared:
    path: .dart_frog_path_dependencies\shared

you will notice that we have \ not /.

• Deploy : to Cloud Run you will get this error:
  Because server depends on shared from path which doesn't exist (could not find package shared at ".dart_frog_path_dependencies\shared"), version solving failed.
