Hello this is the code I'm using:

  menuItemButtonContainer: {
    marginRight: 1,
    marginLeft: 1,
    marginTop: 1,
    marginBottom: 1,
    paddingRight: 1,
    paddingLeft: 1,
    paddingTop: 1,
    paddingBottom: 1,
    borderRadius: 10,
    overflow: 'hidden',
    position: "absolute",
    backgroundColor: 'white',
    borderWidth: 1,
    borderColor: colors.navy
  },

but for some reason the top right Corner is not round. I've been cudgeling my brain for a day.
