How to get token and use in another page in Flutter

Question

My app needs to login, then get the token to access the data. I already succeeded to get the token from the response but my question is how to store the token and then use the token on another page.

Answer 1

You can use shared_preferences :

in pubspec.yaml:

dependencies:
  shared_preferences: ^0.5.6+2

After getting the token:

addTokenToSF() async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  prefs.setString('token', token);
}

To retrieve the token:

getTokenFromSF() async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  String tokenValue = prefs.getString('token');
  return tokenValue;
}
