getString method

String getString(
  1. String key, [
  2. String defaultValue = ""
])

Implementation

String getString(String key, [String defaultValue = ""]) {
  final ckey = key.toNativeUtf8().cast<ffi.Char>();
  final cdefault = defaultValue.toNativeUtf8().cast<ffi.Char>();
  final crval = calloc<ffi.Pointer<ffi.Char>>();
  cfeatures2d.cv_flann_IndexParams_getString(ref, ckey, cdefault, crval);
  calloc.free(ckey);
  calloc.free(cdefault);

  final rval = crval.value.cast<ffi.Char>().toDartString();
  calloc.free(crval);
  return rval;
}
