callbackHelpers → List<Function Function(Function)>: final
exportedFunctions → Map<Function, Pointer<NativeType>>: final
nullptr → Pointer<Never>: Represents a pointer into the native C memory corresponding to "NULL", e.g. a pointer with address 0.
final
signatures → Map<String, String>: final

initSignatures([int pointerSizeBytes = 4]) → void
initTypes([int pointerSizeBytes = 4]) → void: Must be called before working with wasm_ffi to initalize all type sizes.
pointerFromFunctionImpl<T extends Function>(Function func, WasmTable table, Memory memory) → Pointer<NativeFunction<T>>
registerOpaqueType<T extends Opaque>([int? size]) → void: Must be called with each type that extends Opaque before attemtping to use that type.
sizeOf<T extends NativeType>() → int: Number of bytes used by native type T.
