Flutter image upload to laravel backed is returning 401 error. My backed have database fields name, middelName , and profilePic The api works fine on postman but on flutter picking image from gallery and camera its not working i have implemented internet permission on all manifests i used Vpn but error 401
here is flutter code
Future uploadImage() async{
final uri =Uri.parse("https://www.compaytarining.com/api/exrecise2/");
var request =http.MultipartRequest('POST',uri);
request.fields["name"]=nameController.text;
request.fields["middelName"] = mnameController.text;
var pic= await http.MultipartFile.fromPath("profilePic", _image.path);
request.files.add(pic);
var response = await request.send();
print(response.statusCode);
if(response.statusCode==200)
{
print('ImageUploaded');
}
else
{
print("Error");
}
}
Gallery Image
File _image;
final picker=ImagePicker();
Future getImage() async
{
final pickedImage=await picker.getImage(source: ImageSource.gallery);
setState(() {
_image=File(pickedImage.path);
});
}
Many thanks
Hello check it may be error is from your response which is when you return an api response may be u set it to return 401.

In my flutter app, if the user is signing in for the first time, he will be directed to profile page where he gets to key in his personal details and upload his profile pic. now my issue is with the profile pic. First of all, Im using Image picker package.
Future pickImage(ImageSource source) async {
try {
final image = await ImagePicker().pickImage(
source: source);
if (image == null) return;
final UserImage = File(image.path);
setState(() => this.image = UserImage );
}on PlatformException catch (e){
Utils.showSnackBar(e.message);
}
}
But with this code alone, everytime the app gets restarted the image will be null. So I tried to upload the image to the Firebase Storage when the user picks an image and generate a url:
Future uploadImage () async {
FirebaseStorage storage = FirebaseStorage.instance;
Reference ref = storage.ref().child(userID.toString());
UploadTask uploadTask = ref.putFile(image!);
uploadTask.whenComplete(() async {
url = await ref.getDownloadURL(); }
).catchError((onError){
print(onError);
});
return url;
}
But again every time I restart the app, the url will be null.
What is the best way to save the image permenantly when the user signs in for the first time.
edit: I want to store the image locally so that the user doesnt need an internet connection to load the image everytime he open the app.
Your answers and responses are highly appreciated.
you need to get folder directory first
Future<String> getStorageDirectory() async {
if (Platform.isAndroid) {
return (await getExternalStorageDirectory()).path;
} else {
return (await getApplicationDocumentsDirectory()).path;
}
}
Add image in path
uploadImage() async{
String dir= getStorageDirectory();
File directory = new File("$dir");
if (directory.exists() != true) {
directory.create();
}
final image = await ImagePicker().pickImage(
source: source);
if (image == null) return;
final userImage = File(image.path);
var newFile = await userImage.writeAsBytes(/* image bytes*/);
await newFile.create();
}
Description:
I'm using (image_picker: ^0.8.5+3) package to pick the images from gallery and camera and then upload them on backend server (django by using django rest framework)
Issue:
Image is getting null outside picker function, even though state has been set by using setSatet(() {}) method
Failed Solutions:
I tried to save the image locally before uploading the image on the backend, But image still shown null once its used or referenced outside picker function
Note: backend API's works fine and i can upload images by using postman
picker function:
// Get image from gallery and store it locally
Future<File?> _getFromGallery() async {
PickedFile? image = await ImagePicker.platform.pickImage(source: ImageSource.gallery);
if (image == null) {
return null;
}
final File file = File(image.path);
final Directory directory = await getApplicationDocumentsDirectory();
final imagepath = directory.path;
final String fileName = path.basename(image.path);
File newImage = await file.copy('$imagepath/$fileName');
setState(() {
_imagelocal = newImage;
print('image.path1');
print(_imagelocal!.path);
});
}
Uploading image function:
_uploadimage() async {
Map<String,String> header = {
"Content-Type":"application/octet-stream)"
};
print("uploaded image invoked");
var request = http.MultipartRequest('POST', Uri.parse('http://192.168.1.15:8000/api/uploadimage'));
// request.files.add(await http.MultipartFile('image',http.ByteStream(image.openRead()).cast(),await image.length(),filename:image.name, contentType: MediaType('image', 'jpg')));
request.files.add(await http.MultipartFile('LoadModelImage',http.ByteStream(_imagelocal!.openRead()).cast(),await _imagelocal!.length(),));
request.headers.addAll(header);
//for completeing the request
var response =await request.send();
//for getting and decoding the response into json format
var responsed = await http.Response.fromStream(response);
final responseData = json.decode(responsed.body);
if (response.statusCode==201) {
print("SUCCESS");
print(responseData);
}
else {
print("ERROR");
}
}
I am using the firebase_storage: ^8.0.6 package on flutter web. I want to upload image to firebase storage that I get using FilePicker package.
The problem is that the new package uses the putFile() method to upload files. But File from dart:io doesn't work on flutter web and it also doesn't accept the File object from dart:html.
I can upload image as Blob using the putBlob() method but then it doesn't upload it as image type but it's type is application/octet-stream. I don't want to upload the image file as a blob.
Future<String> uploadImage(PlatformFile file) async {
try {
TaskSnapshot upload = await FirebaseStorage.instance
.ref(
'events/${file.name}-${DateTime.now().toIso8601String()}.${file.extension}')
.putBlob(Blob(file.bytes));
String url = await upload.ref.getDownloadURL();
return url;
} catch (e) {
print('error in uploading image for : ${e.toString()}');
return ';
}
}
How to fix this issue?
You can use the putData() method to send the image and set it's metadata as a image.
Future<String> uploadImage(PlatformFile file) async {
try {
TaskSnapshot upload = await FirebaseStorage.instance
.ref(
'events/${file.path}-${DateTime.now().toIso8601String()}.${file.extension}')
.putData(
file.bytes,
SettableMetadata(contentType: 'image/${file.extension}'),
);
String url = await upload.ref.getDownloadURL();
return url;
} catch (e) {
print('error in uploading image for : ${e.toString()}');
return '';
}
}
putData() method takes Uint8List by default.
Uploading images using TaskSnapshot is not working on my flutter web project.
I used firebase_storage: ^8.1.3 .
Following code is working for my web project.
String nameImage = DateTime.now().millisecondsSinceEpoch.toString();
Reference _reference = FirebaseStorage.instance
.ref()
.child('images/$nameImage.png}');
await _reference
.putData(
await image.readAsBytes(),
SettableMetadata(contentType: 'image/jpeg'),
)
.whenComplete(() async {
await _reference.getDownloadURL().then((value) {
user.profilePictureURL = value;
FireStoreUtils.firestore
.collection(USERS)
.doc(user.userID)
.update({'profilePictureURL': user.profilePictureURL});
});
});
You can still use .putFile when you use the File.fromUri() constructor and get the Uri from the PlatformFile object using Uri.dataFromBytes and passing the bytes to it.
The code below contains changes that should remove the error:
TaskSnapshot upload = await FirebaseStorage.instance
.ref(
'events/${file.name}-${DateTime.now().toIso8601String()}.${file.extension}')
.putFile(File.fromUri(Uri.dataFromBytes(file.bytes.toList())));
Flutter 2 announced just few days ago and some packages updated for web like Image Picker. I'm trying to get image and upload it to cloud storage. Image picker working very well but when
I want to upload image to storage it gives me error.
Unsupported operation: Platform._operatingSystem
UI Code
onImageSelect: (selectedImage) async {
try {
final url = await Get.find<FirebaseStorageService>()
.uploadProfilePicture(
customer.uuid, File(selectedImage.path));
print(url);
} catch (e) {
print(e);
}
customer.profileImageUrl = selectedImage.path;
_isImageSelected = true;
}),
Service Class funciton:
class FirebaseStorageService {
final FirebaseStorage _firebaseStorage = FirebaseStorage.instance;
Reference _storageReference;
Future<String> uploadProfilePicture(
String userID, File uploadingImagePath) async {
_storageReference = _firebaseStorage
.ref()
.child(userID)
.child('images')
.child("profile-photo.png");
var uploadTask = _storageReference.putFile(uploadingImagePath);
var url = await (await uploadTask).ref.getDownloadURL();
return url;
}
}
I tried flutter clean and flutter upgrade. I also searched old questions and some of them used html.File instead of dart:io library but firebase_storage:7.0.0 package only accept File class which is from dart:io library.
Code work on Android and IOS but not web.
I'm using stable channel.
I have been working for few since yesterday to try upload an image to azure blob storage taken using mobile camera form iOS/Android device.
I am able to upload the files but for some reason they being corrupted not able to open the image uploaded.
Please check the image error while opening the uploaded image
I am using flutter package http with different approach all work in uploading image file to azure blob store but it gets corrupted somehow , I tried forcing the ContentType to image/jpeg but no help.
Here is code I am using an http API -
takePicture() async {
final pickedFile = await picker.getImage(source: ImageSource.camera);
setState(() {
if (pickedFile != null) {
_image = File(pickedFile.path);
String fileName = basename(pickedFile.path);
uploadFile(fileName, image);
} else {
print('No image selected.');
}
});
}
First approach -->
http.Response response = await http.put(
uri,
headers: {
"Content-Type": 'image/jpeg',
"X-MS-BLOB-TYPE": "BlockBlob",
},
body: image.path,
);
print(response.statusCode);
Using Approach second -->
final data = image.readAsBytesSync();
var dio = Dio();
dio.options.headers['x-ms-blob-type'] = 'BlockBlob';
dio.options.headers['Content-Type'] = 'image/jpeg';
try {
final response = await dio.put(
'$url/$fileName?$token',
data: data,
onSendProgress: (int sent, int total) {
if (total != -1) {
print((sent / total * 100).toStringAsFixed(0) + "%");
}
},
);
print(response.statusCode);
} catch (e) {
print(e);
}
Approach third -->
var request = new http.MultipartRequest("PUT", postUri);
request.headers['X-MS-BLOB-TYPE'] = 'BlockBlob';
request.headers['Content-Type'] = 'image/jpeg';
request.files.add(
new http.MultipartFile.fromBytes(
'picture',
await image.readAsBytes(),
),
);
request.send().then((response) {
uploadResponse.add(response.statusCode);
}, onError: (err) {
print(err);
});
Help here is much appreciated.
If you want to upload the image to Azure Blob Storage in the flutter application, you can use the Dart Package azblob to implement it. Regarding how to use the package, please refer to here.
For example
import 'package:image_picker/image_picker.dart';
import 'package:flutter/material.dart';
import 'package:azblob/azblob.dart';
import 'package:mime/mime.dart';
...
//use image_picker to get image
Future uploadImageToAzure(BuildContext context) async {
try{
String fileName = basename(_imageFile.path);
// read file as Uint8List
Uint8List content = await _imageFile.readAsBytes();
var storage = AzureStorage.parse('<storage account connection string>');
String container="image";
// get the mine type of the file
String contentType= lookupMimeType(fileName);
await storage.putBlob('/$container/$fileName',bodyBytes: content,contentType: contentType,type: BlobType.BlockBlob);
print("done");
} on AzureStorageException catch(ex){
print(ex.message);
}catch(err){
print(err);
}
Unfortunately, the multipart form is causing break of image. I don't know how it works on azure side, because there is little or no information about multipart uploads, but it's clearly broken because of multipart form. I replicated the problem in .net core application and whenever i am using multipart form data to upload image - it is broken. When i am using simple ByteArrayContent - it works. I couldn't find flutter equivalent to ByteArrayContent, so i am lost now :( The package mentioned by #Jim is useless for me, because i want to give clients sas url, so they have permission to upload image on client side. I do not want to store azure storage account secrets in flutter app.
EDIT. I found the solution to send raw byte data with Dio package. You can do that also with http package.
final dio = new Dio();
final fileBytes = file.readAsBytesSync();
var streamData = Stream.fromIterable(fileBytes.map((e) => [e]));
await dio.put(uploadDestinationUrl,
data: streamData,
options: Options(headers: {
Headers.contentLengthHeader: fileBytes.length,
"x-ms-blob-type": "BlockBlob",
"content-type": "image/jpeg"
}));
