如何将屏幕标题放在每个屏幕的标题中？

Question

我需要帮助我了解屏幕在我的应用程序中的行为。

我刚刚注意到，无论我正在浏览什么屏幕，标题顶部的屏幕标题始终是“订单”。 当然，我希望每个标题都显示屏幕标题，所以我认为我的导航文件中缺少一些信息。

但是，我真的不知道在哪里或如何在标题中添加屏幕标题。 但是，我将屏幕的名称/标题放在每个堆栈中。屏幕。

请您指导我，帮助我并向我解释我的错误在哪里，好吗？ 感谢您阅读我。

由于您在堆栈屏幕中嵌套了 BottomTabNavigation。堆栈屏幕的标题将始终相同。

import {getFocusedRouteNameFromRoute} from '@react-navigation/native';
const Stack = createStackNavigator();
const Tab = createBottomTabNavigator();

const screenOptionStyle = {
  headerStyle: {
    backgroundColor: '#F78400',
  },
  headerTintColor: 'white',
  headerBackTitle: 'Back',
  backgroundColor: '#f7f6f6',
};

function getHeaderTitle(route) {
  const routeName = getFocusedRouteNameFromRoute(route) ?? 'OrdersTab';

  switch (routeName) {
    case 'OrdersTab':
      return i18n.t('orders.title');
    case 'DashboardTab':
      return i18n.t('dashboard.title');
    case 'ToolsTab':
      return i18n.t('tools.title');
    case 'SettingsTab':
      return i18n.t('settings.title');
  }
}

export const MainStackNavigator = () => {
  return (
    <Stack.Navigator screenOptions={screenOptionStyle}>
      <Stack.Screen
        name="Orders"
        component={BottomTabNavigator}
