如何從我的應用程式中洗掉標題？為什么顯示標題？
我想從標題中洗掉標題，因為每個頁面都有自己的標題，而該標題會占用螢屏空間。
我不明白為什么顯示它。我正在學習一個教程，并且在我經歷的很多次中，我都看不到洗掉它的方法。我遵循了官方檔案，但我無法擺脫這個無意義的標題。
導航是從 AppStack.js 檔案處理的，顯示的標題標題是從 <Tab.Navigator> <Tab.Screen /> </Tab.Navigator> 處理的，但這實際上是底部選項卡，但是，它們是也顯示在標題中。我展示了一些我無法洗掉的影像
如何洗掉這個不必要的標題？
我有正確的依賴項：

你可以添加 options={{ headerShown: false }}
<Tab.Screen
name="Messages"
component={ChatScreen}
options={({ route }) => ({
headerShown: false,
tabBarVisible: getTabBarVisibility(route),
tabBarIcon: ({ color, size }) => (
<Ionicons
name="chatbox-ellipses-outline"
color={color}
size={size}
/>
),
})}
