有没有办法把 `options` 变成像 `navigationOptions` 一样的函数?

Is there anyway to turn `options` into a function same like `navigationOptions` do?

目前,我正在上一门课程:Multiplatform Mobile App Development with React Native 在 coursera 中,每次讲座后我都被卡住了,因为讲师使用 react-navigation@2.0.1但我想确保学习最新版本(v5)。在这个讲座中,他创建了一个堆栈导航器并将一个图标带到屏幕上,例如,

import {createStackNavigator} from 'react-navigation';
import { Icon } from 'react-native-elements';

const MenuNavigator = createStackNavigator(
  {
    Menu: {
      screen: Menu,
      navigationOptions: ({ navigation }) => ({
        headerLeft: (
          <Icon
            name="menu"
            size={24}
            color="white"
            onPress={() => navigation.toggleDrawer()}
          />
        ),
      }),
    },
    Dishdetail: { screen: Dishdetail },
  },
  {
    initialRouteName: 'Menu'
  }
);

其中 navigationOptions 可以是对象,也可以是接受 props 的函数。

我转换成这样,

import { createStackNavigator } from '@react-navigation/stack';
import { Icon } from 'react-native-elements';

const MenuNavigator = createStackNavigator();
function MenuNavigatorScreen() {
  return (
    <MenuNavigator.Navigator
      initialRouteName="Menu"
      screenOptions={HeaderOptions}
    >
      <MenuNavigator.Screen
        name="Menu"
        component={Menu}
      />
      <MenuNavigator.Screen
        name="Dishdetail"
        component={Dishdetail}
        options={{ headerTitle: 'Dish Detail' }}
      />
    </MenuNavigator.Navigator>
  );
}

但我对如何将 navigationOptions 功能转换为我的代码感到困惑。因为他们的 docs 没有告诉我如何将我的 options 对象变成一个函数来带来 navigation prop?

还有一件事是他正在使用 drawerIcon,

const MainNavigator = createDrawerNavigator(
  {
      navigationOptions: {
        drawerLabel: 'Login',
        drawerIcon: ({ tintColor }) => (
          <Icon
            name="sign-in"
            type="font-awesome"
            size={24}
            color={tintColor}
          />
        ),
      }
...

但我在抽屉导航中没有找到任何相关的drawerIcon docs
如果有人帮我解决这个问题,我衷心感谢。

首先,options prop can be used to configure individual screens inside the navigator. And headerLeft is a function that returns a React element to display on the left side of the header. When a function is used, it receives several arguments when rendered (onPress, label, labelStyle, and more - check types.tsx 为完整列表)。

options = {
    ({
        navigation
    }) => ({
        headerLeft: () => ( <
            Icon name = 'menu'
            size = {
                24
            }
            color = 'white'
            onPress = {
                () =>
                navigation.toggleDrawer()
            }
            />
        )

    })
}

对于 drawerIcon 使用:

options = {
    {
        drawerIcon: ({
            tintColor
        }) => ( <
            Icon name = 'home'
            type = 'font-awesome'
            size = {
                24
            }
            color = {
                tintColor
            }
            />
        )
    }
}
