Animated Splash Screen showing white page - flutter

i wanted to use the AnimatedSplashScreen but in my case it didnt work.
This is the AnimatedSplashScreen displayed in my app:
Here my SplashScreen-Class:
class SplashScreen extends StatelessWidget {
const SplashScreen({super.key});
#override
Widget build(BuildContext context) {
final user = AuthService().currentUser;
String nextScreen =
user != null ? RoutesEnum.homePage : RoutesEnum.loginPage;
return AnimatedSplashScreen(
duration: 1500,
splash: Icons.home,
nextScreen: LoginPage(),
nextRoute: nextScreen,
splashTransition: SplashTransition.rotationTransition,
);}}
And my main.dart where the MaterialApp is created:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(MaterialApp(
debugShowCheckedModeBanner: false,
theme: mainTheme,
home: const SplashScreen(),
routes: {
//RoutesEnum.splashScreen: (context) => const SplashScreen(),
RoutesEnum.loginPage: (context) => LoginPage(),
RoutesEnum.signUpPage: (context) => SignUpPage(),
RoutesEnum.homePage: (context) => HomePage(),
},
));
}
What am I doing wrong?
Thanks for ypur help.
Edit:
This is my LoginPage:
class LoginPage extends StatefulWidget {
#override
_LoginPageState createState() => _LoginPageState();
}
class _LoginPageState extends State<LoginPage> {
final authService = AuthService();
final emailcon = TextEditingController();
final passwordcon = TextEditingController();
#override
Widget build(BuildContext context) {
return Scaffold(

}
else
{
authService
.signInWithEmailAndPassword(
email: emailcon.text.toString(),
password: passwordcon.text.toString(),
)
.then(
(value) => {
if (value)
{
Navigator.pushReplacementNamed(

}
},
),
}
},
),
addVerticalSpace(20),
const Text("- OR -"),

},
),
},
),
addVerticalSpace(20),

title: "Toast",
tapfun: () {
toastmessage(
authService.currentUser == null
? "NULL"
: authService.currentUser!.email.toString(),
);
},
),
],
),
),
Padding(

}
}

Use below-mentioned package:
https://pub.dev/packages/flutter_native_splash
This package automatically generates iOS, Android, and Web-native code for customising this native splash screen background colour and splash image. Supports dark mode, full screen, and platform-specific options.

I found the mistake.
In the MaterialApp the theme-Property makes the trouble. When i remove that it works. Why is that so?

Provider returning null when rebuilding Flutter app

I'm pretty new to flutter and I'm trying to make a login system using providers. It seems to be working when I test the login. But when I rebuild the app the provider returns a null value. Any help would be appreciated.
The screen to check for employee data. If it exist it should redirect to the home page. And if it doesn't, it should redirect to the login authenticate page
Landing Page
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
class Landing extends StatefulWidget {
#override
_LandingState createState() => _LandingState();
}
class _LandingState extends State<Landing> {
//AuthService auth = new AuthService();
#override
Widget build(BuildContext context) {
Future<Employee> getuserdata() => Employee_preferences().getEmployee();
return MultiProvider(
providers: [
ChangeNotifierProvider(
create: (_) => AuthService(),
),
ChangeNotifierProvider(
create: (_) => Employee_Provider(),
)
],
child: MaterialApp(
title: 'ClockServe',
theme: ThemeData(primarySwatch: Colors.blue),
home: FutureBuilder(
future: getuserdata(),
builder: (context, snapshot) {
switch (snapshot.connectionState) {
case ConnectionState.none:
case ConnectionState.waiting:
return CircularProgressIndicator();
default:
if (snapshot.hasError) {
return Text('Error:${snapshot.error}');
} else if (snapshot.data.empId == null) {
return AuthenticatePage();
} else {
return HomePage(emp: snapshot.data);
}
}
}),
routes: {
'/navigatorPage': (context) => NavigatorPage(),
'/homePage': (context) => HomePage(),
'/authenticate': (context) => AuthenticatePage(),
'/attendancePage': (context) => AttendanceScanner()
},
),
);
}
}
The homepage. The page will hold employee information. Landing page is correctly redirecting to this page but for some reason the provider is returning null
HomePage
class HomePage extends StatefulWidget {
final Employee emp;
const HomePage({Key key, this.emp}) : super(key: key);
#override
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
//to do: add back end
//use futurebuilder to return user object
//using futureprovider to get snapshot data of user object from database

Employee emp = Provider.of<Employee_Provider>(context).emp;
print(emp.empEmail);

],
),
),
),
);
}
}
Future navigateToScanPage(context) async {
Navigator.push(

}

Flutter/Dart - Text value not showing correctly

I am trying to create a shopping cart using provider and display the number of items currently in the cart on my homepage. When I create my cart icon with a text widget overlaid, the value being shown does not reflect the number of items in the cart.
Here is my code:
class OurShoppingBasketIcon extends StatelessWidget {
const OurShoppingBasketIcon({Key key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Align(
alignment: Alignment.center,
child: InkWell(
onTap: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => ShoppingBasketScreen()),
);
},
child: Stack(
children: <Widget>[
new Icon(
Icons.shopping_cart_outlined,
color: Colors.white,
),
new Positioned(
right: 0,
child: new Container(
padding: EdgeInsets.all(1),
decoration: new BoxDecoration(
color: Colors.red,
borderRadius: BorderRadius.circular(6),
),
constraints: BoxConstraints(
minWidth: 12,
minHeight: 12,
),
child: Text(
context.read<ShoppingBasket>().items.length.toString(),
style: new TextStyle(
color: Colors.white,
fontSize: 8,
),
textAlign: TextAlign.center,
),
),
)
],
),
),
);
}
}
This is where the icon is implemented:
class OurHomePage extends StatefulWidget {
#override
_OurHomePageState createState() => _OurHomePageState();
}
class _OurHomePageState extends State<OurHomePage> {
#override
Widget build(BuildContext context) {
return Consumer<OurUser>(
builder: (_, user, __) {
return ChangeNotifierProvider<SignInViewModel>(
create: (_) => SignInViewModel(context.read),
builder: (_, child) {
return Scaffold(
appBar: AppBar(
title: Text("My app"),
actions: [
OurShoppingBasketIcon(),
IconButton(
icon: Icon(
Icons.logout,
color: Colors.white,
),
onPressed: () {
context.read<FirebaseAuthService>().signOut();
},
),
],
),
);
},
);
},
);
}
}
There are 2 items in the cart as of writing this:
But the icon on the homepage does not change:
Here is my main.dart:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(
MultiProvider(
providers: [
Provider(
create: (_) => FirebaseAuthService(),
),
StreamProvider<OurUser>(
create: (context) =>
context.read<FirebaseAuthService>().onAuthStateChanged),
ChangeNotifierProvider.value(
value: ShoppingBasket(),
),
],
child: MaterialApp(theme: OurTheme().buildTheme(), home: OurHomePage()),
),
);
}
perhaps if you watch for the value it will be updated dynamically:
context.watch<ShoppingBasket>().items.length.toString(), //<-- watch instead of read
The OurHomePage needs to be wrapped in the Provider<ShoppingBasket>.
return Provider<ShoppingBasket>(
create: (context) => ShoppingBasket(),
child: Consumer<OurUser>(
builder: (_, user, __) {
return ChangeNotifierProvider<SignInViewModel>(
create: (_) => SignInViewModel(context.read),
builder: (_, child) {
return Scaffold(
appBar: AppBar(
title: Text("My app"),
actions: [
OurShoppingBasketIcon(),
IconButton(
icon: Icon(
Icons.logout,
color: Colors.white,
),
onPressed: () {
context.read<FirebaseAuthService>().signOut();
},
),
],
),
),
);
},
);
I forgot to NotifyListeners() in my Change Notifier class:
class ShoppingBasket extends ChangeNotifier {
Map<String, SingleBasketItem> _items = {};
Map<String, SingleBasketItem> get items {
return {..._items};
}
void addItem(String id) {
_items.putIfAbsent(
id,
() => SingleBasketItem(id),
);
notifyListeners(); //HERE
}

Flutter Web buttons dont work after screen change without refreshing on chrome

Not sure what the issue is here but getting a basic login page setup functionally and after the page switches my sign in or signout buttons dont work (but the FAB button does). Here is my signin code for the button:
RaisedButton(
splashColor: Colors.grey,
onPressed: isLoading
? null
: () => _signInWithGoogle(context),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(40)),
highlightElevation: 0,
child: Padding(
padding: const EdgeInsets.fromLTRB(0, 10, 0, 10),
child: Row(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Image(
Image: AssetImage("images/google_logo.png"),
height: 35.0),
Padding(
padding: const EdgeInsets.only(left: 10),
child: Text(
'Sign in with Google',
style: TextStyle(
fontSize: 20,
color: Colors.grey,
),
),
)
],
),
),
),
My main class:
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MultiProvider(
providers: [
Provider<AuthService>(
create: (_) => AuthServiceAdapter(
initialAuthServiceType: AuthServiceType.firebase,
),
dispose: (_, AuthService authService) => authService.dispose(),
),
],
child: AuthWidgetBuilder(
builder:
(BuildContext context, AsyncSnapshot<FirebaseUser> userSnapshot) {
return MaterialApp(
home: AuthWidget(userSnapshot: userSnapshot),
routes: {
HomeScreen.id: (context) => HomeScreen(
title: 'Mythero',
),
},
debugShowCheckedModeBanner: false,
);
},
),
);
}
}
The auth widget:
class AuthWidget extends StatelessWidget {
const AuthWidget({Key key, #required this.userSnapshot}) : super(key: key);
final AsyncSnapshot<FirebaseUser> userSnapshot;
#override
Widget build(BuildContext context) {
if (userSnapshot.connectionState == ConnectionState.active) {
return userSnapshot.hasData
? HomeScreen(
title: 'Mythero',
)
: SignInPageBuilder();
}
return Scaffold(
body: Center(
child: CircularProgressIndicator(),
),
);
}
}
My signout button
child: RaisedButton(
onPressed: () async {
await auth.signOut();
},
child: Text(
'Sign Out',
),
),
The login and sign out code works but when it navigates to another and then I press one of the buttons it just prints 'Dw' in the terminal output. If I refresh the page then it works just fine.

How to show bottomnavigation bar in all pages in flutter

I am creating an app which has bottomnavigation bar.In that bottomnavigation bar it has 5 items names namely profile,aboutus,home,notifications and cart. Each item names has its own page. Now question is i add a button in homepage and if i click on the button it goes to the new page but it doesn't show the bottomnavigation bar.How do i show the bottomnavigation bar in the new page and also the selected current index. Below is the dart code
Mainpage.dart
class MainPage extends StatefulWidget {
#override
_MainPageState createState() => _MainPageState();
}
class _MainPageState extends State<MainPage> {
int _currentIndex = 0;
final tabs = [
Profile(),
AboutUs(),
Home(),
Notifications(),
CartPage(),
];
#override
void initState() {
super.initState();
_currentIndex = 2;
}
#override
Widget build(BuildContext context) {
return Consumer<Cart>(
builder: (context, cart, child) {
return PlatformScaffold(
body: tabs[_currentIndex],
bottomNavBar: PlatformNavBar(
android: (_) => MaterialNavBarData(
type: BottomNavigationBarType.fixed,
),
ios: (_) => CupertinoTabBarData(),
currentIndex: _currentIndex,
itemChanged: (index) => setState(
() {
_currentIndex = index;
},
),
items: [
BottomNavigationBarItem(
icon: PlatformWidget(
ios: (_) => Icon(CupertinoIcons.person),
android: (_) => Icon(Icons.person),
),
title: Text('Profile'),
),
BottomNavigationBarItem(
icon: PlatformWidget(
ios: (_) => Icon(CupertinoIcons.info),
android: (_) => Icon(Icons.info),
),
title: Text('About Us'),
),
BottomNavigationBarItem(
icon: PlatformWidget(
ios: (_) => Icon(CupertinoIcons.home),
android: (_) => Icon(Icons.home),
),
title: Text('Home'),
),
BottomNavigationBarItem(
icon: PlatformWidget(
ios: (_) => new Image.asset(
"assets/notification.png",
height: 21.0,
color: Colors.grey[600],
),
android: (_) => Icon(Icons.notifications),
),
title: Text(
'Notifications',
style: TextStyle(fontSize: 12.0),
),
),
BottomNavigationBarItem(
icon: PlatformWidget(
ios: (_) => Icon(CupertinoIcons.shopping_cart),
android: (_) => Stack(
children: <Widget>[
Icon(Icons.shopping_cart),
cart.count == 0 ? new Container(height: 0, width: 0,)
: new Positioned(
right: 0,
child: new Container(
padding: EdgeInsets.all(1),
decoration: new BoxDecoration(
color: Colors.red,
borderRadius: BorderRadius.circular(6),
),
constraints: BoxConstraints(
minWidth: 12,
minHeight: 12,
),
child: new Text(
'${cart.count}',
style: new TextStyle(
color: Colors.white,
fontSize: 8,
),
textAlign: TextAlign.center,
),
),
)
],
),
),
title: Text('Cart'),
),
],
),
);
},
);
}
}
Homepage.dart
class Home extends StatefulWidget {
#override
_HomeState createState() => _HomeState();
}
class _HomeState extends State<Home> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: RaisedButton(
onPressed: (){
Navigator.of(context).push(MaterialPageRoute(
builder: (context) => NewPage()));
},
child: Text('New Page'),
),
),
);
}
}
Newpage.dart
class NewPage extends StatefulWidget {
#override
_NewPageState createState() => _NewPageState();
}
class _NewPageState extends State<NewPage> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
),
);
}
}
I use this method to add a widget which is common to all pages:
MaterialApp(
title: 'Flutter Demo',
initialRoute:"/home",
routes: [
...
],
builder: (context, child) {
return Stack(
children: [
child!,
Overlay(
initialEntries: [
OverlayEntry(
builder: (context) {
return YourCustomWidget(); *//This widget now appears on all pages*
},
),
],
),
],
);
},
);
You can have a Scaffold as a parent of all these pages, and have a BottomNavigationBar on the Scaffold, and a PageView as the body of the Scaffold:
Scaffold(
body: PageView(
controller: MyController(),
children: [
MyPage1(),
MyPage2(),
//...
],
onPageChanged: myOnPageChanged,
),
bottomNavigationBar: MyNavBar(),
)

Showing selected image in alert dialog in flutter

How can i show the selected image in my alert dialog ?
In my app, i added an alert dialog which has the camera button. When user clicks the camera button, another alert dialog asks to select file from gallery. After the user selects image file from gallery, i want to show the image in the alert dialog with the camera button, but the image shows only after reopening the alert dialog.
I have posted my code below. I am new to flutter. Please can someone help me? Thanks in advance.

That is because you would need to setState() however you can't do that in an alert dialogue as it doesn't have its own state, the workaround for that would be to have the dialogue be its own stateful widget. Please check out this article as it shows how to do that. If you faced problems let me know!

Future getImageFromCamera() async {
var x = await ImagePicker.pickImage(source: ImageSource.camera);
imagePath = x.path;
image = Image(image: FileImage(x));
}
}
Try this solution with GestureDetector() .it works
onTap:()async{
var image = await ImagePicker.pickImage(
source: ImageSource.gallery).whenComplete((){
setState(() {
});
}
);
setState(() {
_image = image;
});
},
