Flutter Shared Preferences

Flutter Shared Preferences - android

Guys how to transfer data when I login.. For example when I login the transfer data are User ID, email and password.. So if I want to add something that requires the user id how do I call it?
This is my login method
void login() async {
if(passController.text.isNotEmpty && emailController.text.isNotEmpty) {
var response = await http.post(
Uri.parse("url"),
body: ({
'email': emailController.text,
'password': passController.text,
}));
if (response.statusCode == 200) {
final body = jsonDecode(response.body);
print(body.toString());
List<dynamic> data = body["Details"];
print(data[0]['email']);
pageRoute(data[0]['name']);
} else {
ScaffoldMessenger.of(context)
.showSnackBar(SnackBar(content: Text("Wrong password")));
}
} else {
ScaffoldMessenger.of(context)
.showSnackBar(SnackBar(content: Text("Sila isi tempat kosong")));
}
}
void pageRoute(data) async {
//STORE VALUE IN SHARED PREFERENCES
SharedPreferences pref = await SharedPreferences.getInstance();
await pref.setString("login", data);
Navigator.of(context).pushAndRemoveUntil(
MaterialPageRoute(builder: (context) => nav()),
(route) => false);
This is where I want to take the user id without put it on the textfield.
import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:shared_preferences/shared_preferences.dart';
import 'package:http/http.dart' as http;
import '../Utils/lib.dart';
class CarList extends StatefulWidget {
const CarList({Key? key}) : super(key: key);
#override
State<CarList> createState() => _CarListState();
}
class _CarListState extends State<CarList> {
var userController = TextEditingController();
// late SharedPreferences logindata;
// String? Email;
final pref = Pref();
// late String name;
// late String registeration_no;
#override
void initState() {
// TODO: implement initState
super.initState();
initial();
}
void initial() async {
if (pref.isLogin()) {
final body = jsonDecode(pref.getLogin());
print(body['Details']['user_id'].toString());
}
return null;
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: ListView(
children: <Widget>[
Container(
padding: const EdgeInsets.all(10),
child: TextField(
controller: userController,
decoration: const InputDecoration(
border: OutlineInputBorder(),
suffixIcon: Icon(Icons.email),
labelText: 'User ID',
),
),
),
Container(
margin: EdgeInsets.all(25),
child: TextButton(
child: Text('test',
style: TextStyle(fontSize: 20.0,
color: Colors.blueAccent,
backgroundColor: Colors.white),
),
onPressed: () {
list();
},
),
)
]
)
);
}
void list() async {
{
var response = await http.post(
Uri.parse("url"),
body: ({
'user_id': userController.text,
}));
if (response.statusCode == 200) {
final body = jsonDecode(response.body);
// final SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
// sharedPreferences.setString('email', emailController.text);
pref.saveLogin(true, response.body);
print(body.toString());
ScaffoldMessenger.of(context)
.showSnackBar(SnackBar(content: Text("Successfully Login")));
}
}
}
}
Im kinda new with this flutter so might thankful with your help

You can do something like this:
This is store data in pageRoute.
void login() async {
if (passController.text.isNotEmpty && emailController.text.isNotEmpty) {
var response = await http.post(
Uri.parse("http://servisjer.me-tech.com.my/api/Login"),
body: ({
'email': emailController.text,
'password': passController.text,
}));
if (response.statusCode == 200) {
final body = jsonDecode(response.body);
print(body.toString());
List<dynamic> data = body["Details"];
print(data[0]['email']);
pageRoute(Data(data[0]['email'], data[0]['user_id']));
} else {
ScaffoldMessenger.of(context)
.showSnackBar(SnackBar(content: Text("Wrong password")));
}
} else {
ScaffoldMessenger.of(context)
.showSnackBar(SnackBar(content: Text("Sila isi tempat kosong")));
}
}
void pageRoute(Data data) async {
MySharedPreferences().storeUser(data);
Navigator.of(context).pushAndRemoveUntil(
MaterialPageRoute(builder: (context) => nav()), (route) => false);
}
MySharedPreferences
class MySharedPreferences {
Future<void> storeUser(Data data) async {
SharedPreferences prefs = await SharedPreferences.getInstance();
prefs.setString("email", data.email);
prefs.setInt("user_id", data.userId);
}
Future getUserId() async {
SharedPreferences prefs = await SharedPreferences.getInstance();
var userId = prefs.getInt("user_id");
return userId;
}
}
In CarList, retrieve data using this way
#override
void initState() {
MySharedPreferences().getUserId().then((value) {
setState(() {
userController.text = value.toString();
});
});
//TODO: IMPLEMENT INITSTATE
super.initState();
}
Data
class Data {
var email;
var userId;
Data(this.email,this.userId);
}

if you're trying to record, try setting the bitRate to 48000 (worked for me on iOS when it wasn't showing the waveforms when recording).
final RecorderController recorderController = RecorderController()
..androidEncoder = AndroidEncoder.aac
..androidOutputFormat = AndroidOutputFormat.mpeg4
..iosEncoder = IosEncoder.kAudioFormatMPEG4AAC
..sampleRate = 44100
..bitRate = 48000;

Error: Could not find the correct Provider<AuthState> above this AuthPage Widget

ERROR:
══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following ProviderNotFoundException was thrown building AuthPage(dirty, state:
_AuthPageState#7ac1c):
Error: Could not find the correct Provider above this AuthPage Widget
This happens because you used a BuildContext that does not include the provider
of your choice. There are a few common scenarios:
You added a new provider in your main.dart and performed a hot-reload.
To fix, perform a hot-restart.
The provider you are trying to read is in a different route.
Providers are "scoped". So if you insert of provider inside a route, then
other routes will not be able to access that provider.
You used a BuildContext that is an ancestor of the provider you are trying to read.
Make sure that AuthPage is under your MultiProvider/Provider.
This usually happens when you are creating a provider and trying to read it immediately.
For example, instead of:
Widget build(BuildContext context) {
return Provider<Example>(
create: (_) => Example(),
// Will throw a ProviderNotFoundError, because `context` is associated
// to the widget that is the parent of `Provider<Example>`
child: Text(context.watch<Example>()),
),
}
consider using builder like so:
Widget build(BuildContext context) {
return Provider<Example>(
create: (_) => Example(),
// we use `builder` to obtain a new `BuildContext` that has access to the provider
builder: (context) {
// No longer throws
return Text(context.watch<Example>()),
}
),
}

Initialize your provider 1st. Refer this https://stackoverflow.com/a/68418866/16467763.
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(
MultiProvider(
providers: [
ChangeNotifierProvider<AuthState>(
create: (context) => AuthState(),
),
],
child: MyApp(),
),
);
}

class AuthPageWidget extends StatelessWidget {
final int page;
final String? uid;
const AuthPageWidget({
Key? key,
required this.page,
this.uid,
}) : super(key: key);
#override
Widget build(BuildContext context) {
final state = AuthState(page, uid ?? '');
return ChangeNotifierProvider(
create: (_) => state,
child: ChangeNotifierProvider.value(
value: state,
child: AuthPage(page: page, uid: uid),
),
);
}
}
You should move the ChangeNotifierProvider to your main.dart like this
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
final state = AuthState(page, uid ?? '');
runApp(
MaterialApp(
debugShowCheckedModeBanner: false,
home: ChangeNotifierProvider(
create: (_) => state,
child: AuthPage(page: page, uid: uid),
),
),
);
}
OR
class SomeWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: ChangeNotifierProvider(
create: (_) => state,
child: ChangeNotifierProvider.value(
value: state,
child: AuthPage(page: page, uid: uid),
),
)
),
);
}
}

I have done.
Deploy the script project as an API executable.
Provide a properly scoped OAuth token for the execution.
Ensure that the script and the calling application share a common Cloud Platform (GCP)
project.
Enable the Google Apps Script API

Flutter switch toggles off on its own

I have created a flutter starter kit that allowes me to switch between themes in-app.
Now this works great but there is a small issue.
I have placed the switch button in the settings screen,
but when I go to another screen and then back to the settings screen
- it would seem that the switch button goes to Off mode on its own.
I'm attaching an image and my code on github so that you guys can see what I mean.
class ThemeSwitchState extends State {
bool switchControl = false;
Future<bool> darkMode() async {
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
return sharedPreferences.getBool("isDark");
}
#override
Widget build(BuildContext context) {
return FutureBuilder<bool>(
future: darkMode(),
builder: (context, _snapshot) {
return Transform.scale(
scale: 1.5,
child: Switch(
value: _snapshot.data ?? false,
onChanged: (value) {
save(value);
setState(() {
});
},
activeColor: CustomColors().duskBlue,
activeTrackColor: CustomColors().noroGrey,
inactiveThumbColor: CustomColors().lureGrey,
inactiveTrackColor: CustomColors().noroGrey,
),
);
},
);
}
void save(bool value) async{
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
await sharedPreferences.setBool("isDark", value);
}
void toggleSwitch(bool value) {
ThemeChanger _themeChanger =
Provider.of<ThemeChanger>(context, listen: false);
if (switchControl == false) {
setState(() {
switchControl = true;
});
print('Theme is Dark');
_themeChanger.setTheme(CustomThemes.darkTheme.copyWith(
textTheme:
CustomThemes.darkTextTheme(CustomThemes.darkTheme.textTheme)));
} else {
setState(() {
switchControl = false;
});
print('Theme is Light');
_themeChanger.setTheme(CustomThemes.lightTheme.copyWith(
textTheme:
CustomThemes.lightTextTheme(CustomThemes.lightTheme.textTheme)));
}
}
}

You can use SharedPreferences from https://pub.dev/packages/shared_preferences
to save the last value of the CheckBox
I wrote an example
import 'package:flutter/material.dart';
import 'package:shared_preferences/shared_preferences.dart';
class Settings extends StatefulWidget {
#override
_SettingsState createState() => _SettingsState();
}
class _SettingsState extends State<Settings> {
Future<bool> darkMode() async{
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
return sharedPreferences.getBool("isNight");
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Column(
children: <Widget>[
Text("Night Mode"),
FutureBuilder<bool>(
future: darkMode(),
builder: (context, _snapshot){
return Checkbox(
value: _snapshot.data ?? false,
onChanged: (value){
save(value);
setState(() {
toggleSwitch(value);
});
},
);
},
)
],
),
),
);
}
void save(bool value) async{
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
await sharedPreferences.setBool("isNight", value);
}
}
EDIT: WITH SWITCH
import 'package:flutter/material.dart';
import 'package:shared_preferences/shared_preferences.dart';
class Settings extends StatefulWidget {
#override
_SettingsState createState() => _SettingsState();
}
class _SettingsState extends State<Settings> {
Future<bool> darkMode() async{
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
return sharedPreferences.getBool("isNight");
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Column(
children: <Widget>[
Text("Night Mode"),
FutureBuilder<bool>(
future: darkMode(),
builder: (context, _snapshot){
return Switch(
value: _snapshot.data ?? false,
onChanged: (value){
save(value);
setState(() {
});
},
);
},
)
],
),
),
);
}
void save(bool value) async{
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
await sharedPreferences.setBool("isNight", value);
}
}
UPDATE use value instead of switchControl
void toggleSwitch(bool value) {
ThemeChanger _themeChanger =
Provider.of<ThemeChanger>(context, listen: false);
if (value) {
setState(() {
switchControl = true;
});
print('Theme is Dark');
_themeChanger.setTheme(CustomThemes.darkTheme.copyWith(
textTheme:
CustomThemes.darkTextTheme(CustomThemes.darkTheme.textTheme)));
} else {
setState(() {
switchControl = false;
});
print('Theme is Light');
_themeChanger.setTheme(CustomThemes.lightTheme.copyWith(
textTheme:
CustomThemes.lightTextTheme(CustomThemes.lightTheme.textTheme)));
}
}
}
