Detailed Description

An interface for a responder that can process a key press event and decides whether to handle the event asynchronously.

To use this class, add it to a |FlutterKeyboardManager| with |addPrimaryResponder|.

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.

handlePress:callback:

- (void) handlePress: (nonnull FlutterUIPressProxy *)  press callback: (ios(13.4))  API_AVAILABLE

required

Process the event.

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

Reimplemented in FlutterChannelKeyResponder, and FlutterEmbedderKeyResponder.

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 FlutterChannelKeyResponder, and FlutterEmbedderKeyResponder.
