Answer 1

This is how I have done it in React Navigation 2 release: I call the openDrawer() method from a StackNavigator that is a child navigator of the DrawerNavigator.

This is my DrawerNavigator:

export const Drawer = DrawerNavigator(
    {
        MyAccount: {screen: TabsStack},
    });


export const TabsStack = StackNavigator({

    Tabs: {
        screen: Tabs, navigationOptions: ({navigation}) => ({
            headerLeft: (
                 navigation.openDrawer()}>
                    
                )
        })
