我坚持在里面添加保存方法navigationOptions,请你帮我做正确的方法.

            style = {{paddingLeft : 20}}
            onPress = {() => navigate('DrawerOpen')}

};

export const Stack1 = StackNavigator({
    Screen1: {
        screen: screen1,
        navigationOptions: {
            header: ( props ) => ({
                left: <DrawerIcon { ...props } />
            }),
