Why is React Native App.js navigation undefined in App.js?

Question

export default function App ({navigation})

There is a function that starts with and contains <Stack.Navigator>.

But when I want to use the navigation feature and use "navigation.navigate ('Lead') in onPress

TypeError: undefined is not an object evaluating react navigation

I get an error. My English is not very good. Please help me on this topic. Now I'm adding the sample codes to you.

You can pass the navigation or rout prop into options in the stack.screen like this

options={({navigation})=>({
    'Your code here'
})}

I have edited it with your code for you.

        <Stack.Screen name="Lead" component={LeadScreen}
         options={({ navigation }) => ({
             title: 'Müşteri Adayları',
             headerStyle: { backgroundColor: '#e8a200' },
             headerTintColor: 'white',
             headerTitleStyle: { fontWeight: 'bold', color: '#fff' },
             headerRight: () => (
                <TouchableOpacity activeOpacity={0.4} 
                   underlayColor='transparent' onPress={() => 
                   console.log(navigation)} style={{ marginRight: 12 }}>
                    <Icon
                       style={styles.icon}
                          fill='#FFFFFF'
                          name='plus-outline'
                      />
                  </TouchableOpacity>
                  )
         })} />
