stderr property

Stream<List<int>> stderr

Returns a stream that reads from stderr.

To use this, you must enable WASI when instantiating the module, and set captureStderr to true.

Implementation

Stream<List<int>> get stderr {
  if (_wasiEnv == nullptr) {
    throw WasmError("Can't capture stderr without WASI enabled.");
  }
  return _stderr ??= runtime.getWasiStderrStream(_wasiEnv);
}
