Issue
I'm trying to select multiple images so for this i used pickMultiImage
method of image_picker.
Images are displaying on screen, but i need their path so that i can use it to upload on cloudinary.com
.
here is my code
List<XFile>? _imageFileList3 = [];
Future pickMultipleImage() async {
if (_imageFileList3!.length == 4) {
showDialog(
context: context,
builder: (BuildContext context) {
return LoginSucessDailog(
text: 'You can\'t add more than 4 images.',
title: 'Warning.',
img: 'assets/img/alert.png');
});
} else {
try {
var image = await _picker.pickMultiImage();
//here i'll be using cloudinary code
setState(() {
_imageFileList3!.addAll(image!);
});
print(image);
print(_imageFileList3!.length);
setState(() {
isImageLoading = false;
});
} on CloudinaryException catch (e) {}
}
}
this is the part of code i'm using to upload images on Cloudinary using cloudinary_public package
CloudinaryResponse response = await cloudinary.uploadFile(
CloudinaryFile.fromFile(image!.path,
resourceType: CloudinaryResourceType.Image),
);
displaying images like this
addProductsImages() {
if (_imageFileList3!.length != 0) {
return SizedBox(
height: 80,
width: MediaQuery.of(context).size.width * 0.9,
child: GridView.builder(
shrinkWrap: true,
itemCount: _imageFileList3!.length,
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 4,
),
itemBuilder: (BuildContext context, int index) {
return Padding(
padding: const EdgeInsets.all(8.0),
child: Stack(children: [
ClipRRect(
borderRadius: BorderRadius.circular(10.0),
child: Image.file(
File((_imageFileList3![index].path)),
width: MediaQuery.of(context).size.width * 0.35,
height: MediaQuery.of(context).size.height * 0.17,
fit: BoxFit.cover,
),
),
Align(
alignment: Alignment.topRight,
child: buildCancelIcon(Colors.white, () {
setState(() {
// _imageFileList!.removeAt(index);
});
}, Icons.cancel))
]));
}));
} else {
return Padding(
padding: const EdgeInsets.only(left: 70),
child:
Row(crossAxisAlignment: CrossAxisAlignment.center, children: []));
}
}
please help how to do this, or is there any way to select multiple images at once and upload them on cloudinary.
Solution
Please refer to below example code where user can pick maximum 5 images
Using these packages
images_picker: ^1.2.4
flutter_image_compress: ^0.7.0
class PickMultipleImagesScreen extends StatefulWidget {
const PickMultipleImagesScreen({Key key}) : super(key: key);
@override
_PickMultipleImagesScreenState createState() =>
_PickMultipleImagesScreenState();
}
class _PickMultipleImagesScreenState extends State<PickMultipleImagesScreen> {
final ValueNotifier<bool> attachMultipleImages = ValueNotifier<bool>(false);
List compressedPhotosList = ["place_holder"];
int maxImagesCount = 5;
pickPhotos() async {
List<Media> photosList = [];
photosList = await ImagesPicker.pick(
count: (compressedPhotosList != null &&
(compressedPhotosList.isNotEmpty) &&
(compressedPhotosList.length > 1))
? (maxImagesCount + 1 - compressedPhotosList.length)
: maxImagesCount,
pickType: PickType.all,
language: Language.System,
cropOpt: CropOption(
aspectRatio: CropAspectRatio(600, 400),
),
);
if (photosList != null && photosList.isNotEmpty && photosList.length > 0) {
for (int i = 0; i < photosList.length; i++) {
File photoCompressedFile =
await compressImage(File(photosList[i].path));
print("Images List: $photosList");
print("Path of UnCompressed File: ${photosList[i].path}");
compressedPhotosList.insert(
0,
photoCompressedFile.path.toString(),
);
print("Path of Compressed File: ${photoCompressedFile.path}");
print("Compressed Images List: $compressedPhotosList");
}
attachMultipleImages.value = !attachMultipleImages.value;
}
}
Future<File> compressImage(File file) async {
final filePath = file.absolute.path;
final lastIndex = filePath.lastIndexOf(new RegExp(r'.png|.jp'));
final splitted = filePath.substring(0, (lastIndex));
final outPath = "${splitted}_out${filePath.substring(lastIndex)}";

final compressedImage = await FlutterImageCompress.compressAndGetFile(

minWidth: 1000,

return compressedImage;
