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.
