Hi, You can display a loader during the process. You can declare a boolean to determine whether to display a loader. Then inside the onpressed function on starting the process of upload you can make the boolean true and call setState() and make that false again once upload is complete. Give it a try, and reach out if you face any difficulty.
Bro, excelent video. Other youtube videos about upload photos to storage are outdated. Apart from that your explanations are wonderful. Greetings from Argentina!
this is probably the best explanation available for how to load and retrieve image on firebase storage. but one problem when we take a new camera picture, it overlaps the previous one because of same name 'name'. how to tackle that as we will not be able to call the previous image from firestore DB though the url get saved there but they all point to same picture in storage.
You can create a unique name for your file and create a reference with that name, you can use the current timestamp to create the unique name. I think I have mentioned that in the video!!!! And regarding accessing the file through its url, I have created a separate video on the topic. (ua-cam.com/video/t0nWkruqFO4/v-deo.html) I hope this will help.
Go to your imports at the top make sure you have "import 'dart:io';" and if you have the html import that automatically got added by your IDE remove it.That worked for me
On clicking the image the preview should appear on the right, and below the preview the file name appears, on clicking the file name the image is opened in a new tab.
Hi! Very well explained video,! I'm not getting any errors but when I select the image in my iOS app, it doesn't follow through with creating the folder nor uploading the image. Any special config for iOS is necessary? Thanks!
Hi, If it is not working then you should be able to find some information about the error in the log. If you can find it please share, it help in understanding the issue. Is it working in Android? Thanks for reaching out.
@@droidmonk4820 Hey! Thank you for the quick response. The issue is the following: flutter: Error caught: [firebase_storage/unauthorized] User is not authorized to perform the desired action.
The value you are passing to the details page is null for some reason. Try using the debugger or simply print the value that you are passing to the details page and verify it is correct. Also keep in mind: you will need to install firebase to you Flutter project before using Firebase services. (ua-cam.com/video/kwLz-0e6Eo0/v-deo.html)
There may be two possible locations of error: 1. Inside the details page, you may have defined a variable of type Map to hold the data that you pass from the list page. But some reason you passing null 2. Inside the builder function of the FutureBuilder while getting the API response from snapshot.data. You may be getting null as the response. Check whether using the correct reference or not--- _reference = FirebaseFirestore.instance.collection('shopping_list').doc(itemId);
Thank you so much for the video. Its very detailed and comprehensive. However I seem to be getting this error when I try to run the app. "Error: The argument type 'Future Function()' can't be assigned to the parameter type 'Future Function(App)?'. - 'Future' is from 'dart:async'. - 'App' is from 'package:firebase_core_web/src/interop/app.dart'" Please help... :)
It seems you are passing wrong url somewhere. Once check the code where you are creating the reference, or any other places where you are using any URL.
Here are some possible causes and solutions: Missing Firebase configuration: Ensure that you have properly configured Firebase in your Flutter project by following the setup instructions provided by Firebase. This includes adding the google-services.json file for Android or GoogleService-Info.plist for iOS to your Flutter project. Incorrect Firebase initialization: Make sure that you have initialized Firebase correctly in your Flutter app. This is usually done in the main.dart file using Firebase.initializeApp(). Missing or incorrect bucket name: Double-check that you have specified the correct default storage bucket in your Firebase project settings. The bucket name should be in the format gs://your-project-id.appspot.com. Permissions issue: Ensure that the Firebase Storage service is enabled for your project and that the necessary permissions are set correctly. Check the Firebase console to verify the project settings. Network issues: Sometimes, network issues can also cause this error. Ensure that your device has a stable internet connection and can access Firebase services. Outdated Firebase SDK: Make sure you are using the latest version of the Firebase SDK for Flutter. You can check for updates using Flutter's package manager (pubspec.yaml).

that is a very useful video but i have an error which catched by try & catch which said (Unsupported operation: Platform._operatingSystem) can you please help me
I had the same issue, I fixed it by making sure I had the import import 'dart:io'; , and instead of try catch blocks I had to make if (!kIsWeb) {} and if(kIsWeb) conditions first. KisWeb are conditional to let your code know if you're running on a web app or an android/iOS application. inside these blocks you can add the try and catch methods.
Hi Rajesh, please verify whether you are using the correct field name while parsing the data , and that you have a value for the field in the corresponding firestore document.

Can we upload multiple images at the same time
You'll need to use a loop...
Future uploadImages() async {
setState(() {
_isUploading = true;
});
final storageRef = FirebaseStorage.instance.ref();
final firestore = FirebaseFirestore.instance;
for (var image in _images) {
try {
String fileName = Uuid().v4(); // Generate unique file name
final imageRef = storageRef.child("images/$fileName.jpg");
// Upload image to Firebase Storage
final uploadTask = await imageRef.putFile(image);
// Get the download URL
final downloadUrl = await imageRef.getDownloadURL();
// Save metadata to Firestore
await firestore.collection("images").add({
"url": downloadUrl,
"uploadedAt": Timestamp.now(),
});
debugPrint("Image uploaded and metadata saved!");
} catch (e) {
debugPrint("Error uploading image: $e");
}
}
setState(() {
_isUploading = false;
_images = []; // Clear the images after uploading
});
}

When i click one of the items in order to display item details it show the following error
: type null is not a subtype of type string flutter
The value you are passing to the details page is null for some reason. Try using the debugger or simply print the value that you are passing to the details page and verify it is correct.

Thx you for replying,
Now it’s show me details page when i click on item but it show anything say Type Null is not a subtype of Map
