Struct MainThreadDispatcher 

pub struct MainThreadDispatcher { /* private fields */ }

Worker-safe handle for posting short operations to Flutter’s main thread.

Dispatch is always asynchronous, including when called from the main thread. This prevents a callback from unexpectedly re-entering Dart or mutable platform state in the middle of an FFI call.

Posts task for a later turn of the main event loop.
