type Dart_IsolateShutdownCallback = Option<unsafe extern "C" fn(isolate_group_data: *mut c_void, isolate_data: *mut c_void)>;

An isolate shutdown callback function.

This callback, provided by the embedder, is called before the vm shuts down an isolate. The isolate being shutdown will be the current isolate. It is safe to run Dart code.

This function should be used to dispose of native resources that are allocated to an isolate in order to avoid leaks.
