Struct KeyEventManager 

pub struct KeyEventManager { /* private fields */ }

A singleton class that processes key messages from the platform and dispatches converted messages accordingly.

KeyEventManager receives platform key messages by handle_key_data, and sends converted events to HardwareKeyboard for record keeping and dispatching.

Flutter owns this from ServicesBinding; here it is the App’s singleton.
