ExRouter Add onTransitionToTop method, have a best idear?

[virtoolswebplayer]

after readed , if you have a best idear?

my case is login=>tabbar=>tab1=>login , there is something i want to do

1. when hardwareBackPress pressed don't pop to login route, only allow logout <Button>do it.
2. when logout <Button> pressed , i use Actions.login so it's ok and with animation, but the root Router stack like this [launch, login, tabbar, tab1Router, login], i want root Router stack is ['login'] and should with animation.

how to do root stack[launch, login, tabbar, tab1Router, login] => [login] and with transform animation

two choice

choice 1: set login Route's type = 'reset' , but there no transform animation it look like 'replace'

<Route name="login" component={Login}  hideNavBar={true} type="reset" backable={false}/>

choice 2: try use ExNavigator' method transitionToTop, so i add some code to ExRouter.js

<Route name="login" component={Login}  hideNavBar={true} type="transitionToTop" backable={false}/>

/**
  old code is blow
  componentWillUnmount() {
      if (this === Actions.currentRouter.delegate) {
        Actions.currentRouter = null;
      }
  }
*/

  componentWillUnmount() {
      if (Actions.currentRouter && this === Actions.currentRouter.delegate) {
        Actions.currentRouter = null;
      }
  }

/**
  add a new method for ExRouter Class
*/
  onTransitionToTop(route:Route, props:{ [key: string]: any}) {
    if (this.props.onTransitionToTop) {
      const res = this.props.onTransitionToTop(route, props);
      if (!res) {
        return false;
      }
    }

    const navigator = this.refs.nav;
    let router:BaseRouter = route.parent;
    router._stack=[route.name];
    // you can use navigator.transitionToTop or  navigator.immediatelyResetRouteStack + navigator.push
    // navigator.immediatelyResetRouteStack + navigator.push is more beter , 
    // if root stack only have one route  eg ['someroute']
    // navigator.transitionToTop(new ExRouteAdapter(route, props));
    //  i use navigator.immediatelyResetRouteStack + navigator.push
    navigator.immediatelyResetRouteStack([]);
    navigator.push(new ExRouteAdapter(route, props));
    return true;
  }

My Router Setting

  render() {
    /*
     android点击返回,回退到上一个路由
     */
    BackAndroid.addEventListener('hardwareBackPress', () => {
      /**
       * check props.backable 
       * <Route  backable={false}/>
       */
        if ( typeof Actions.currentRouter.currentRoute.props.backable !== 'undefined') {
          return true;
        }

        try {
          Actions.pop();
          return true;
        }
        catch (err) {
          return true;
        }

        return true;
      }
    );
