modelFolderExists static method

bool modelFolderExists(
  1. String modelId,
  2. int framework
)

Check if a model folder exists.

Implementation

static bool modelFolderExists(String modelId, int framework) {
  final lib = _lib();
  if (lib == null || _callbacksPtr == null) return false;
  final fn = lib.lookupFunction<
      Int32 Function(Pointer<RacFileCallbacksStruct>, Pointer<Utf8>, Int32,
          Pointer<Int32>, Pointer<Int32>),
      int Function(
          Pointer<RacFileCallbacksStruct>,
          Pointer<Utf8>,
          int,
          Pointer<Int32>,
          Pointer<Int32>)>('rac_file_manager_model_folder_exists');

  final modelIdPtr = modelId.toNativeUtf8();
  final existsPtr = calloc<Int32>();
  try {
    fn(_callbacksPtr!, modelIdPtr, framework, existsPtr, nullptr);
    return existsPtr.value == RAC_TRUE;
  } finally {
    calloc.free(modelIdPtr);
