找不到变量:尝试从堆栈导航器内部导航时出现导航错误 [英] Can’t find variable: navigation error when trying to navigate inside from inside the stack navigator

问题描述

我添加了一个标题按钮，当我点击该按钮时，我想转到应用程序中的特定屏幕，代码如下:

I've added a header button and I'd like to go to a specific screen in my app when I click on that button, here's the code:

function ActionBarIcon(props) {
  return (
    <TouchableOpacity onPress={props.onPress}>
      <Image
        source={{uri : 'https://static.thenounproject.com/png/261370-200.png'}}
        style={{ width: 30, height: 30, marginRight : 15 }} />
    </TouchableOpacity>
  );
}

export default function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName="Orders">

        <Stack.Screen name="Orders" component={HomePage} options = {{
          headerRight : props => <ActionBarIcon {...props}
          onPress={() => {
            navigation.navigate('Create Order')
          }} />
        }}/>

        <Stack.Screen name="Order Details" component={DetailsPage} />
        <Stack.Screen name="Create Order" component={CreateOrderPage} />

      </Stack.Navigator>
    </NavigationContainer>
  );
}

如您所见，我想创建订单页面，当单击标题按钮时，我收到一条错误消息，提示找不到变量:导航".感谢您的反馈！

As you can see, I want to go to create order page, when the header button is clicked but I'm getting an error saying "Can’t find variable: navigation". I appreciate your feedback!

推荐答案

在 headerRight 中一定不能获取导航，所以你可以试试下面的建议

It must not be getting navigation inside headerRight, so you may try the below suggestion

 <Stack.Screen name="Orders" component={HomePage} options={({ navigation, route }) => ({
      headerRight: props => <ActionBarIcon {...props}
          onPress={() => {
            navigation.navigate('Create Order') 
          }} />
    })}

    />
