如何用 react-navigation 删除双 header?

How to remove double header with react-navigation?

我的 React Native 0.61.5 使用 react-navigation 5.1。这是根导航代码:

const BTab = createBottomTabNavigator();
const Stack = createStackNavigator();
export default function App() {

  //const Appscreen = () => (<AppScreen data={data}/>);

  return (
    <NavigationContainer>
      <Stack.Navigator InitialRouteName="Splash">
        <Stack.Screen name="Splash" component={SplashScreen}}/>
        <Stack.Screen name="App" component={AppScreen} } />
      </Stack.Navigator>

    </NavigationContainer>
  );
}

组件AppScreenreturn像这样的堆栈:

return (
    <NavigationContainer independent={true}>
      <BTab.Navigator>
          <BTab.Screen name="Event" component={Eventstack} />
          <BTab.Screen name="Group" component={Groupstack} />
          <BTab.Screen name="Contact" component={Contactstack} />
      </BTab.Navigator>
    </NavigationContainer>
  );

我注意到屏幕上有两个 header:
