在成功授权下调用回调函数

Question

我是用反应性新的开发应用程序的新手。我正在尝试通过成功授权到下一个应用程序场景进行过渡。这是我的代码

login = () => {
   firebaseApp.auth().signInWithEmailAndPassword(email, password
   ).then((userData) => {
       var uid = userData.uid;
       localStorage.save('uidKey', uid)
       console.log('uidKey');
       // transition
     }
   ).catch((error) => {
     AlertIOS.alert(
      'Login Failed!',
      'Please try again'
     );
   }); }); }

我知道如何通过按按钮触发过渡。通过添加这条代码

onPress={() => Actions.root()}>

，但我不知道如何从回调调用此功能。在字符串//transition

中

如此友善，帮助我

您应该能够导入动作，然后启动相同的过渡：

import { Actions } from 'react-native-router-flux';
...
login = () => {
    firebaseApp.auth().signInWithEmailAndPassword(email, password
    ).then((userData) => {
            var uid = userData.uid;
            localStorage.save('uidKey', uid)
            console.log('uidKey');
            // transition
            Actions.root()
        }
    ).catch((error) => {
        AlertIOS.alert(
            'Login Failed!',
            'Please try again'
        );
    }); }); }
