Question posted in 
I want my user to be redirected to his own profile but I have a problem. This is an old code that I am trying to change and when user it is redirected to his own profile first it appears a sliding panel( with the story he uploaded) I want that sliding up panel to disappear and user to be send automatically to his own profile .. to understand better what I am saying I will let a video here : https://imgur.com/a/Y7t4Qs9
Here it’s the code for the homepage button:
IconButton(
icon: const Icon(
Icons.perm_identity,
color: Colors.black,
),
onPressed: () {
User user = FirebaseAuth.instance.currentUser!;
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => UserHandling(
uid: user.uid,
),
),
);
})
Here it’s the code for user HadelingPage
class UserHandling extends StatefulWidget {
final String uid;
const UserHandling({super.key, required this.uid});
@override
State<UserHandling> createState() => UserHandlingState();
}
class UserHandlingState extends State<UserHandling> {
@override
void initState() {
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: StoryProfile(
uid: widget.uid,
currentUserID: widget.uid,
),
),
);
}
}
Here it’s the code for StoryPage:
class StoryProfile extends StatefulWidget {
final String uid;
final String currentUserID;
const StoryProfile({
super.key,
required this.uid,
required this.currentUserID,
});
@override
State<StoryProfile> createState() => StoryProfileState();
}
class StoryProfileState extends State<StoryProfile> {
List<Story> storiesList = [];
PanelController panelController = PanelController();
Color bgColor = Colors.transparent;
late String currentUser;
@override
void initState() {
super.initState();
currentUser = FirebaseAuth.instance.currentUser!.uid;
FirebaseFirestore.instance
.collection('Users/${widget.uid}/Story')
.get()
.then((value) {
if (value.docs.isEmpty) {
panelController.close();
}
for (var element in value.docs) {
storiesList.add(Story(
url: (element.data() as Map)['url'],
media: (element.data() as Map)['media'],
id: element.id,
));
}
setState(() {});
getStoryData();
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: SlidingUpPanel(
color: bgColor,
controller: panelController,
onPanelOpened: () => setState(() => bgColor = Colors.white),
onPanelClosed: () => setState(() => bgColor = Colors.transparent),
panelBuilder: (ScrollController sc) {
UserPage pg = UserPage();
pg.scrollController = sc;
return pg;
},
collapsed: const Center(
child: Column(
children: [
Icon(
Icons.keyboard_arrow_up,
color: Colors.white,
),
Text(
"SwipeUp to see more information",
style: TextStyle(color: Colors.white),
),
],
),
),
body: storiesList.isNotEmpty
? StoryScreen(
stories: storiesList,
uid: currentUser,
currentUserID: currentUser,
)
: const Center(
child: Text(
'Aici trebuie adaugate imagini/videoclipuri cu serviciile dvs. cu scopul de promovarenFolositi butonul "adauga story" ',
textAlign: TextAlign.center,
),
),
),
);
}
void getStoryData() async {
QuerySnapshot<Map<String, dynamic>> query = await FirebaseFirestore.instance
.collection('Users/$currentUser/Story')
.get();
storiesList.clear();
if (query.docs.isNotEmpty) {
for (DocumentSnapshot<Map> doc in query.docs) {
setState(() {
storiesList.add(Story.fromDocument(doc));
});
}
}
}
}
And I want that icon button to send the user automatically to UserPage that is in the StoryScreen , but if I add instead of UserHandling(uid: user.uid, ), just UserPage() it’s not working, gives red screen
Here it’s the userPage
class UserPage extends StatefulWidget {
late ScrollController scrollController;
UserPage({super.key});
@override
State<UserPage> createState() => UserProfile();
}
class UserProfile extends State<UserPage> {
bool isFileImage = false;
late User user;
late File pickedFile;
String? userImage;
String? address;
String? precise_address;
String? userName;
String? facebookUrl;
String? instagramUrl;
String? tikTokUrl;
TextEditingController facebookController = TextEditingController();
TextEditingController instagramController = TextEditingController();
TextEditingController tiktokController = TextEditingController();
late String userId;
Random randomGenerator = Random();
String? searchString;
String? country;
QuerySnapshot? querySnapshot;
@override
void initState() {
super.initState();
initUser();
}
initUser() async {
user = FirebaseAuth.instance.currentUser!;
userId = user.uid;
logger.e("user id at init user =$userId");
getSocialData();
getData();
}
final TextEditingController _userNameController = TextEditingController();
late File _image;
final picker = ImagePicker();
Future getImage() async {
final pickedFile = await picker.pickImage(source: ImageSource.gallery);
if (pickedFile != null) {
setState(() {
_image = File(pickedFile.path);
});
Reference storageReference = FirebaseStorage.instance.ref();
Uint8List imageData = _image.readAsBytesSync();
storageReference
.child("Users Profile")
.child(userId)
.putData(imageData)
.then((uploadTask) async {
var dowurl = await uploadTask.ref.getDownloadURL();
String url = dowurl.toString();
Map<String, dynamic> urlNull = {
'avatarUrl': url,
};
DocumentReference prereference =
FirebaseFirestore.instance.collection('Users').doc(userId);
await FirebaseFirestore.instance.runTransaction((transaction) async {
transaction.update(prereference, urlNull);
});
});
}
}
Future<void> displayPrediction(Prediction p, BuildContext context) async {
var placeId = p.placeId;
var address = await FlGeocoder(Constants.googlePlaceKey)
.findAddressesFromPlaceId(placeId!);
setState(() {
searchString = p.description!;
});
FirebaseFirestore.instance.collection('Users').doc(userId).update({
"precise_location": searchString,
});
country = address.first.country!.longName;
}
var addresses;
var first;
double lat = 0.0;
double long = 0.0;

Answers
for a faster solution and assuming you are using sliding_up_panel plugin, you can set the parameter defaultPanelState to PanelState.OPEN and panelSnapping to false and set the maxHeight to screen height (MediaQuery.of(context).size.height).
for a more efficient solution please provide the UserPage() widget and the error stack trace that occurs when you pass UserPage() directly instead of the user handling page.
Given the error: LateInitializationError: Field "scrollerController" has not been initialized you need to initialize your scrollController inside initUser() and there is no need to put it in the parent class of your State class so it should be like this.
first delete or comment declaration of scrollController
Secondly initialize it in your userInit() function:
Finally call it directly when you use it (not widget.scrollerController):
