## How to Run a Sample Code

1. Build the Flutter engine that is compatible with OpenHarmony. For details, see https://gitee.com/openharmony-sig/flutter_engine/blob/master/README_EN.md.
2. Download the Flutter SDK that is compatible with OpenHarmony and configure the environment. For details, see https://gitee.com/openharmony-sig/flutter_flutter/blob/master/README_EN.md.
3. Go to the sample directory, for example, **flutter_music_player**, and run `flutter run --local-engine=<path of the OpenHarmony-compatible Flutter engine's build product>`.
