Method Documentation

◆ handleEvent:callback:

- (void) handleEvent: (nonnull NSEvent *)  event
callback: (nonnull FlutterAsyncKeyCallback callback 
required

Process the event.

The |callback| should be called with a value that indicates whether the responder has handled the given event. The |callback| must be called exactly once, and can be called before the return of this method, or after.

◆ syncModifiersIfNeeded:timestamp:

- (void) syncModifiersIfNeeded: (NSEventModifierFlags)  modifierFlags
timestamp: (NSTimeInterval)  timestamp 
required

Synchronize the modifier flags if necessary. The new modifier flag would usually come from mouse event and may be out of sync with current keyboard state if the modifier flags have changed while window was not key.

Reimplemented in FlutterEmbedderKeyResponder.
