降低抽屉打开速度

我在用 createDrawerNavigator 具有 react-navigation 图书馆。

如何降低抽屉打开的速度?

const DrawerStack = createDrawerNavigator(
  {
    Home: {
      screen: HomeStack,
    },
    About: {
      screen: Screen2Stack,
    },
  },
  {
    initialRouteName: 'Home',
    contentOptions: {
      activeTintColor: '#e91e63',
    },
    drawerWidth: 300,
  }
);
