从 react-native 屏幕中删除导航标题 - 堆栈导航

Question

我有一个带有标签栏导航的屏幕，其中每个屏幕都是堆栈导航类型，每个屏幕都定义了几个屏幕。当我从 FamilyMembers 导航到 SingleContact 屏幕时，我不想看到顶部带有后退按钮的导航栏。我希望我在单一联系人中的视图（蓝色视图）从顶部开始。但它似乎虽然我将标题设置为空！请帮忙。

您是否已经像这样在 HomeScreenStack 中修改了 FamilyMembersStack？

    const HomeScreenStack = createStackNavigator({
  Home: {
    screen: HomeScreen,
    navigationOptions: ({ navigation }) => {
      return {
        header: null,
      }
    },
  },

  // modify this Stack

  FamilyMembersStack:{
    screen: FamilyMembersStack,
    navigationOptions: ({ navigation }) => {
      return {
        header: null
      }
    }
  }
  AttendanceHistory: {
    screen: AttendanceHistory,
    navigationOptions: ({ navigation }) => {
      return {
        headerTitle: "Attendance history"
      }
    }
  },
  OrderHistory: {
    screen: OrderHistory,
    navigationOptions: ({ navigation }) => {
      return {
        headerTitle: "Order history"
      }
    }
  }
});

跟进答案，删除以下内容。以便标题将呈现在指定的屏幕上：

 export default class SingleContact extends Component {
    static navigationOptions = {

        header: null, // remove this
    }
    constructor(props) {
        super(props);
        this.state = { userName: "", contacts: [], userID: "", cookie: null, memberShips: [] };
    }
    async componentDidMount() {

    }
    onDataLoaded(result, userName) {

    }
    render() {

//-----------------------------//

const FamilyMembersStack  = createStackNavigator({
  FamilyMembers: {
    screen: FamilyMembers,
    navigationOptions: ({ navigation }) => {     
      return {
        headerTitle: "Family members",
        header:null        
      }
    }
  },
  SingleContact: {
    screen: SingleContact,
    navigationOptions: ({ navigation }) => {     
      return {
        headerTitle: "Contact",
        header:null // and remove this        
      }
    }
  },
});
