Firebase react native loading issue - firebase

Question

I'm new at react native and I try to build an mobile app. I'm using Firebase for applications. When I try to login, it stucks on the loading page. And getting this warning:
Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android as it keeps the timer module awake, and timers can only be called when the app is in the foreground. See https://github.com/facebook/react-native/issues/12981 for more info.
(Saw setTimeout with duration 3600000ms)
What should I do?
Also authentication code is here:
import { AsyncStorage } from 'react-native';
export const SIGNUP = 'SIGNUP';
export const LOGIN = 'LOGIN';
export const AUTHENTICATE = 'AUTHENTICATE';
export const LOGOUT = 'LOGOUT';
let timer;
export const authenticate = (userId, token, expiryTime) => {
return dispatch => {
dispatch(setLogoutTimer(expiryTime));
dispatch({ type: AUTHENTICATE, userId: userId, token: token });
};
};
export const signup = (email, password) => {
return async dispatch => {
const response = await fetch(
'https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=...',
{
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
email: email,
password: password,
returnSecureToken: true
})
}
);
if (!response.ok) {
const errorResData = await response.json();
const errorId = errorResData.error.message;
let message = 'Bir terslik var!';
if (errorId === 'EMAIL_EXISTS') {
message = 'Bu e-posta zaten kayıtlı!';
}
throw new Error(message);
}
const resData = await response.json();
console.log(resData);
dispatch(
authenticate(
resData.localId,
resData.idToken,
parseInt(resData.expiresIn) * 1000
)
);
const expirationDate = new Date(
new Date().getTime() + parseInt(resData.expiresIn) * 1000
);
saveDataToStorage(resData.idToken, resData.localId, expirationDate);
};
};
export const login = (email, password) => {
return async dispatch => {
const response = await fetch(
'https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=...',
{
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
email: email,
password: password,
returnSecureToken: true
})
}
);
if (!response.ok) {
const errorResData = await response.json();
const errorId = errorResData.error.message;
let message = 'Bir terslik var!';
if (errorId === 'EMAIL_NOT_FOUND') {
message = 'Böyle bir e-posta yok!';
} else if (errorId === 'INVALID_PASSWORD') {
message = 'Bu şifre geçersiz!';
}
throw new Error(message);
}
const resData = await response.json();
console.log(resData);
dispatch(
authenticate(
resData.localId,
resData.idToken,
parseInt(resData.expiresIn) * 1000
)
);
const expirationDate = new Date(
new Date().getTime() + parseInt(resData.expiresIn) * 1000
);
saveDataToStorage(resData.idToken, resData.localId, expirationDate);
};
};
export const logout = () => {
clearLogoutTimer();
AsyncStorage.removeItem('userData');
return { type: LOGOUT };
};
const clearLogoutTimer = () => {
if (timer) {
clearTimeout(timer);
}
};
const setLogoutTimer = expirationTime => {
return dispatch => {
timer = setTimeout(() => {
dispatch(logout());
}, expirationTime);
};
};
const saveDataToStorage = (token, userId, expirationDate) => {
AsyncStorage.setItem(
'userData',
JSON.stringify({
token: token,
userId: userId,
expiryDate: expirationDate.toISOString()
})
);
};
