Assets fail to load from workspace packages after migrating from path-based dependencies #177765
Description
- Description
After migrating from path-based package declarations to using Dart workspaces, assets defined within workspace packages no longer load in the Flutter app.
- Steps to Reproduce
Create a workspace setup following the official Dart workspace documentation
Define a package within the workspace that contains assets
Declare the assets in the package's pubspec.yaml
Reference these assets from the main Flutter app
Run the app
- Expected behavior:
Assets load correctly, as they did with path-based dependencies
- Actual behavior:
Assets fail to load
- Minimal Reproduction
I've created a minimal reproduction repository that demonstrates this issue:
https://github.com/moneer-octedia/workspace_assets
- The repository shows:
Working setup with path-based dependencies
Broken setup after migrating to workspaces
Asset declarations in both the package and main app
- Additional Context
This issue may belong to either the Dart pub team or Flutter team. Regardless of where the fix belongs, the workspace documentation should include guidance on handling assets in workspace packages, as this is a common use case when migrating existing projects.
