Missing from this implementation: - Closure/dynamic calls with differing signatures - Overrides with extra optional parameters - Records with same shape defined in different dynamic modules - Avoiding running TFA on dynamic module. - Recompilation of only updateable functions from main module. - Persist wasm def types from main module. Testing is currently done locally via the dynamic_modules package test suite: dart pkg/dynamic_modules/test/runner/main.dart --runtime=dart2wasm Immediately after this lands we can introduce a new step to one of the wasm test matrix configurations that runs the above test suite (the VM has a similar configuration). Change-Id: I3386d84be11b773842d45f4268a62a54c47e352b Tested: Tested via new tests in dynamic_modules package. Tests run locally but will add to existing config.
