showOkAlertDialog function

Future<OkCancelResult> showOkAlertDialog (
  1. {@required BuildContext context,
  2. String title,
  3. String message,
  4. String okLabel,
  5. bool barrierDismissible: true,
  6. AdaptiveStyle alertStyle: AdaptiveStyle.adaptive,
  7. bool useActionSheetForCupertino: false,
  8. bool useRootNavigator: true,
  9. VerticalDirection actionsOverflowDirection: VerticalDirection.up}

Show OK alert dialog, whose appearance is adaptive according to platform

This is convenient wrapper of showAlertDialog. barrierDismissible (default: true) only works for material style, and if it is set to false, pressing OK button is only way to close alert. actionsOverflowDirection works only for Material style currently.
