Answer 1

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
