Anyway to enable 'remember me' function using sharedPreferences in flutter? - flutter

Question

Currently, I have enabled 'keep logging in' function if the user log in once successfully. However, I still want to make a 'remember me' checkbox to save the success login information for user. Can anyone please help me with this?
Need: a checkbox that enables the user to store email and password if the user logged in once successfully.
Code is shown below:
signIn(String email, pass) async {
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
String url = ServerDetails.ip +
':' +
ServerDetails.port +
ServerDetails.api +
'login';
Map<String, String> headers = {"Content-type": "application/json"};
var data = jsonEncode({
'email': email,
'password': pass,
'token': FirebaseNotifications.fcmtoken
});
var jsonResponse = null;
var response = await http.post(url, headers: headers, body: data);
if (response.statusCode == 200) {
jsonResponse = json.decode(response.body);
if (jsonResponse != null) {
setState(() {
_isLoading = false;
});
sharedPreferences.setString("token", jsonResponse['token']);
sharedPreferences.setString(
"token_expire_date", jsonResponse['token_expire_date']);
Navigator.of(context).pushAndRemoveUntil(
MaterialPageRoute(builder: (BuildContext context) => MainPage()),
(Route<dynamic> route) => false);
}
} else {
setState(() {
_isLoading = false;
});
Widget okButton = FlatButton(
child: Text("OK"),
onPressed: () {
Navigator.push(
context, MaterialPageRoute(builder: (context) => MainPage()));
});
setState(() {
AlertDialog alert = AlertDialog(
title: Text("Error message"),
content: Text("Oops! The password is wrong or the email is invalid."),
actions: [
okButton,
],
);
showDialog(
context: context,
builder: (BuildContext context) {
return alert;
},
);
});
print(response.headers);
print(response.body);
}
}

Of course, you can create a simple checkbox for remember me. In the login button, you can check if this checkbox is checked. If it is, you can set email & password in shared_preferences.
Next time, when the user comes again you can get these fields automatically from shared_preferences.
Here is an example.
