how to use build_runner in pub workspaces?

[kjxbyz]

1. The following code must be added to the root pubspec.yaml file

dev_dependencies:
  build_runner: ^2.4.14

Otherwise, the following error will be reported

dart pub -C modules/basic/assets run build_runner build --delete-conflicting-outputs
Deprecated. Use `dart run` instead.
Package "build_runner" is not an immediate dependency.
Cannot run executables in transitive dependencies.
make: *** [asset] Error 65

2. Run the following command in the root directory. Code cannot be generated in the module directory.

dart pub -C modules/basic/assets run build_runner build --delete-conflicting-outputs

build_runner does not have any direct support for pub workspaces - you need to still use it as normal (add the dependency to each sub-packages pubspec etc).

It does support workspaces in the sense that it still works, but it doesn't try to share work across the workspace or anything like that, and each package still has to have the dependency.

I thought we had an open issue for some better support here but I don't see one, so we can leave this open to track that.
