Actually defer loading deferred libraries in dev_compiler #27777

Open munificent opened 7 years ago

munificent commented 7 years ago

dev_compiler supports deferred imports, but the library itself is still eagerly loaded.

It would be groovy if it could hook into some of the module loading APIs and support actually deferring deferred libraries.

This seems like a production use case focused request and we don't plan to address those use cases. We'll leave the issue for enforcing correct code to avoid surprises when using dart2js, but I'll close this one.
