cloudinary_public #

This package allows you to upload media files directly
to cloudinary, without exposing your apiKey or
secretKey.
Getting started #
Add the dependency cloudinary_public: ^0.23.1 to your project:
import 'package:cloudinary_public/cloudinary_public.dart';

final cloudinary = CloudinaryPublic('CLOUD_NAME', 'UPLOAD_PRESET', cache: false);

Check https://cloudinary.com/documentation/upload_images#unsigned_upload on how to create an upload preset.
Using Image Picker Plugin #
var image = await ImagePicker.pickImage(source: ImageSource.camera);

try {
CloudinaryResponse response = await cloudinary.uploadFile(
CloudinaryFile.fromFile(image.path, resourceType: CloudinaryResourceType.Image),
);

print(response.secureUrl);
} on CloudinaryException catch (e) {
print(e.message);
print(e.request);
}

Using Multi Image Picker Plugin #
final images = await MultiImagePicker.pickImages(maxImages: 4);

List<CloudinaryResponse> uploadedImages = await cloudinary.multiUpload(
images
.map(
(image) => CloudinaryFile.fromFutureByteData(
image.getByteData(),
identifier: image.identifier,
),
)
.toList(),
);

print(uploadedImages[0].secureUrl);

Image Transformation #
// CloudinaryImage
final cloudinaryImage = CloudinaryImage('https://res.cloudinary.com/demo/image/upload/front_face.png');
// or using the image public id
final cloudinaryImage = cloudinary.getImage('front_face');

final String url = cloudinaryImage.transform().width(150).height(150).gravity('face').crop('thumb').generate();
// or using the shortcut
final String url = cloudinaryImage.thumbnail(width: 150, height: 150).generate();

// Chain example
final url = cloudinaryImage.transform()
.width(150)
.height(150)
.gravity('face')
.crop('thumb')
.chain()
.radius(20)
.chain()
.effect('sepia')
.chain()
.overlay(cloudinary.getImage('cloudinary_icon'))
.gravity('south_east')
.x(5)
.y(5)
.width(50)
.opacity(60)
.effect('brightness:200')
.chain()
.angle(10)
.generate();
// generates

Upload Progress #
final res = await cloudinary.uploadFile(
CloudinaryFile.fromFile(
_pickedFile.path,
folder: 'hello-folder',
context: {
'alt': 'Hello',
'caption': 'An example image',
},
),
onProgress: (count, total) {
setState(() {
_uploadingPercentage = (count / total) * 100;
});
},
);

Upload In Chunks #
Use chunked upload when file size is more then 100 Megabytes.
By default, the chunk size is set to 20 Megabytes but can be set to as low as 5 Megabytes by using the chunk_size parameter.

final res = await cloudinary.uploadFileInChunks(
CloudinaryFile.fromFile(
_pickedFile.path,
folder: 'hello-folder',
context: {
'alt': 'Hello',
'caption': 'An example upload in chunks',
},
),
chunkSize: 10000000
onProgress: (count, total) {
setState(() {
_uploadingPercentage = (count / total) * 100;
});
