`Could not acquire the lock to C:\Users\Dave\Documents\Scene\flutter_scene\examples\flutter_app.dart_tool\native_assets_builder\shared\flutter_scene_importer.lock.
Target dart_build failed: TimeoutException after 0:05:00.000000: Could not acquire the lock to C:\Users\Dave\Documents\Scene\flutter_scene\examples\flutter_app.dart_tool\native_assets_builder\shared\flutter_scene_importer.lock.
