EmscriptenModule class

Provides access to WebAssembly compiled with emscripten.

WebAssembly compiled with emscripten comes with an <moduleName>.wasm and an additional <moduleName>.js glue JavaScript file. The later is required to be loaded on the page before calling any of this classes functions.

The WebAssembly must have been compiled with the -s MODULARIZE=1 and -s EXPORT_NAME=<moduleName> flags. Futhermore the <moduleName.js> must contain all exported WebAssembly functions that should be usable from dart, so using -s MAIN_MODULE=1 might be advisable.

For a detailed walkthrough on how to create and inject these files, see the example.

On platforms where dart:js is not available, all methods throw UnsupportedErrors.
