Could not acquire lock

[DavidOrakpo]

I am attempting the run the example in the package but I am running into the error below.

`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. 2

FAILURE: Build failed with an exception.`

I have cmake installed, on the master channel and all the other requirements
