/** \mainpage Dynamically Linked Dart API
 *
 * This exposes a subset of symbols from dart_api.h and dart_native_api.h
 * available in every Dart embedder through dynamic linking.
 *
 * All symbols are postfixed with _DL to indicate that they are dynamically
 * linked and to prevent conflicts with the original symbol.
 *
 * Link `dart_api_dl.cc` file into your library and invoke
 * `Dart_InitializeApiDL` with `NativeApi.initializeApiDLData`.
