Amacım, kullanıcı zaten giriş yapmışsa kullanıcıyı Home
bileşenine yönlendirmektir. Kullanıcıya giriş yapabilir ve numaralı telefonu yalnızca _logInUser()
numaralı telefona yeniden yönlendirebilirim . Ancak, Home
bileşenine yeniden yönlendirildiğinde, simulatörü yenilediğimde, uygulama Login
bileşenine geri döner.React Native - Firebase kullanıcısına giriş yapılıyor Ana Sayfa Bileşen
Bu sorunu componentWillMount()
kullanarak ve let user = firebaseApp.auth().currentUser
ayarlamayı denedim. Ancak, user
'u konsola bağladım ancak if
denetimi doğrudan else
ifadesine gider. Herhangi bir anlayış için minnettar olurum!

Üzgünüm, sizin için tam bir cevabım yok. Ancak, [Switch Feature] 'ın (https://github.com/aksonov/react-native-router-flux/blob/master/docs/OTHER_INFO.md#switch-new-feature) burada yararlı olabileceğine inanıyorum. –
