Instance class

Instantiated WebAssembly module.

An Instance can be compiled and instantiated from Uint8List or ByteBuffer source data, or from already compiled Module. When data length exceeds 4 KB, some runtimes may require asynchronous compilation and instantiation via Instance.fromBufferAsync, Instance.fromBytesAsync, or Instance.fromModuleAsync.

Static Methods

fromBufferAsync(ByteBuffer buffer, {Map<String, Map<String, Object>>? importMap, Object? importObject}) → Future<Instance>

Asynchronously compiles WebAssembly Module from ByteBuffer source and instantiates it with imports.

fromBytesAsync(Uint8List bytes, {Map<String, Map<String, Object>>? importMap, Object? importObject}) → Future<Instance>

Asynchronously compiles WebAssembly Module from Uint8List source and instantiates it with imports.

fromModuleAsync(Module module, {Map<String, Map<String, Object>>? importMap, Object? importObject}) → Future<Instance>

Asynchronously instantiates compiled WebAssembly Module with imports.
