React native router flux disable the Android back button to return to the login interface

Using react native router flux, after the user successfully logs in, I want to disable the back button to return to the login screen. However, it seems that I can't find a way to get the current "Scene" or "stack", and then log in: @ h_ 404_ 3@

@H_ 404_ 3@

backAndroidHandler={() => {
                        if (currentScene === afterLoginScreeen) {
                         return true;   
                        }
                    }}

Has anyone tried to deal with the problem@ H_ 404_ 3@

Solution: @ h_ 404_ 3@

Just like my experience on react native router flux @ h_ 404_ 3@

@H_ 404_ 3@

<Scene duration={0} key="main" component={Main} title="Some Title" type={ActionConst.RESET} />

It should be that you need to avoid returning to the login screen @ H_ 404_ 3@
