first create a class where your where https request handle & token store

class Network {
      var  token;
    final string base= "/api";
     //token get when needed 
 _getToken() async {
    SharedPreferences localStorage = await SharedPreferences.getInstance();
     var user = jsonDecode(localStorage.getString('data'));
     token = user['token'];
     }

    //signup 
  signUp(data, apiUrl) async {
    var fullUrl = baseUrl + apiUrl;
    return await http.post(fullUrl,
    body: jsonEncode(data), headers: _setHeaders());
    }

  //login
   signIn(apiUrl) async {
   var fullUrl = baseUrl + apiUrl;
    await _getToken();
     return await http.get(fullUrl, headers: _setHeaders());
   }

  }

in sign up page use this method where you use sign up button on pressed 

void _signUp() async {

var data = {
  'mobile': mobileController.text,
  'password':  mobileController.text,
};

var res = await Network().signUp(data, '/register');
var body = json.decode(res.body);
if (body.statusCode == 200) {
  SharedPreferences localStorage = await SharedPreferences.getInstance();
  localStorage.setString('token', json.encode(body['data']['token']));

  localStorage.setString('data', json.encode(body['data']));

  Navigator.push(
    context,
    new MaterialPageRoute(builder: (context) => Home()),
  );
} else  {
//      errorMessage = "as you want to show ";

 
}


  }

in sign up page , use this method same as sign up pages

void signIn() async {

var data = {'mobile': mobile, 'password': password};
var res = await Network().signIn(data, '/login');
var body = json.decode(res.body);

if (res.statusCode == 200) {
  SharedPreferences localStorage = await SharedPreferences.getInstance();
  localStorage.setString('token', json.encode(body['data']['token']));
  localStorage.setString('data', json.encode(body['data']));
  Navigator.pushReplacement(
    context,
    new MaterialPageRoute(builder: (context) => HomePage()),
  );
} else if (res.statusCode != 200) {
 // mobileError = "These credentials do not match our records.";
}
   }

now you can have the token when u signup/singIn and store token in sharedSharedPreferences whenever you try to acces token just called _getToken() method
