subPackageBarrels static method
Returns barrel import URIs for sub-packages discovered through re-exports.
When a module follows re-exports into sub-packages (e.g., dcli re-exports dcli_core), D4rt scripts may import those sub-packages directly. These barrels need to be registered with the interpreter separately so that module resolution finds content for those URIs.
Implementation
static List<String> subPackageBarrels() {
return [];
}
