I switched from a WasmImports object to a builder pattern: module.instantiate().addMemory(...).addFunction(...).build(); Bug: https://github.com/dart-lang/sdk/issues/37882 Change-Id: I381aa0f7df1fa006ce8d051cd5b4a1bcc1835e46 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/167460 Reviewed-by: Ryan Macnak <rmacnak@google.com> Commit-Queue: Liam Appelbe <liama@google.com>
