Detailed Description

A primary responder of |FlutterKeyboardManager| that handles events by sending the converted events through the embedder API.

This class communicates with the HardwareKeyboard API in the framework.

Method Documentation

getPressedState

- (nonnull NSDictionary *) getPressedState

Returns the keyboard pressed state.

Returns the keyboard pressed state. The dictionary contains one entry per pressed keys, mapping from the logical key to the physical key.

Definition at line 797 of file FlutterEmbedderKeyResponder.mm.

                                         {
  return [NSDictionary dictionaryWithDictionary:_pressingRecords];
}

Referenced by FlutterKeyboardManager::getPressedState.

initWithSendEvent:

- (nonnull instancetype) initWithSendEvent:

(_Nonnull FlutterSendEmbedderKeyEvent)

sendEvent

Create an instance by specifying the function to send converted events to.

The |sendEvent| is typically |FlutterEngine|'s |sendKeyEvent|.

syncModifiersIfNeeded:timestamp:

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

Synthesize modifier keys events.

If needed, synthesize modifier keys up and down events by comparing their current pressing states with the given modifier flags.

Reimplemented from <FlutterKeyPrimaryResponder>.

Definition at line 784 of file FlutterEmbedderKeyResponder.mm.

                             :(NSEventModifierFlags)modifierFlags
                    timestamp:(NSTimeInterval)timestamp {
  FlutterAsyncKeyCallback replyCallback = ^(BOOL handled) {
    // Do nothing.
  };
  FlutterKeyCallbackGuard* guardedCallback =
      [[FlutterKeyCallbackGuard alloc] initWithCallback:replyCallback];
  [self synchronizeModifiers:modifierFlags
               ignoringFlags:0
                   timestamp:timestamp
                       guard:guardedCallback];
