handleRequestAppExitMethodCall:result:

- (void) handleRequestAppExitMethodCall:		(NSDictionary<NSString*, id>*)	data
result:		(FlutterResult)	result

                                      :(NSDictionary<NSString*, id>*)arguments
                                result:(FlutterResult)result {
  NSString* type = arguments[@"type"];
  // Ignore the "exitCode" value in the arguments because AppKit doesn't have
  // any good way to set the process exit code other than calling exit(), and
  // that bypasses all of the native applicationShouldExit shutdown events,
  // etc., which we don't want to skip.
 
  FlutterAppExitType exitType =
      [type isEqualTo:@"cancelable"] ? kFlutterAppExitTypeCancelable : kFlutterAppExitTypeRequired;
