cloudinary_sdk

This is a dart package for Cloudinary API that allows you to upload and manage files in your cloudinary cloud.

Description

This package is intended to be used for signed uploading to your cloud, it allows you to destroy/delete files and makes it easy to access image url with transformations

How to use

Add dependency

# Add this line to your flutter project dependencies
cloudinary_sdk: ^1.0.0+1

and run flutter pub get to download the library sources to your pub-cache.

Initialize a Cloudinary object

final cloudinary = Cloudinary(
      <YOUR_API_KEY>,
      <YOUR_API_SECRET>,
      <YOUR_CLOUD_NAME>
    );

This three params can be obtained directly from your Cloudinary account Dashboard.

Do a single file upload

  final response = await cloudinary.uploadFile(
    filePath,
    resourceType: CloudinaryResourceType.image,
    folder: cloudinaryCustomFolder,
  );
  if(response.isSuccessful ?? false)
    urlPhotos.add(response.secureUrl);

You can also pass an optParams map to do a more elaborated upload according to https://cloudinary.com/documentation/image_upload_api_reference The cloudinary.uploadFile(...) function is fully documented, you can check the description to know what other options you have.

Do a multiple file upload

List<CloudinaryResponse> responses = await cloudinary.uploadFiles(
    pathPhotos,
    resourceType: CloudinaryResourceType.image,
    folder: cloudinaryCustomFolder,
  );
  responses.forEach((response) {
    if(response.isSuccessful ?? false)
      urlPhotos.add(response.secureUrl);
  });

This function does repeatedly calls to cloudinary.uploadFile(...) described in the step above.

Do a single file delete (this will use the cloudinary destroy method)

    final response = await cloudinary.deleteFile(
      url: url,
      resourceType: CloudinaryResourceType.image,
      invalidate: false,
    );
    if(response.isSuccessful ?? false){
      //Do something else
    }

To delete a cloudinary file it´s necessary a public_id, as you can see in the sample code the deleteFile(...) function can delete a file by it's url... You can also pass an optParams map to do a more elaborated delete (destroy) according to https://cloudinary.com/documentation/image_upload_api_reference#destroy_method The cloudinary.deleteFile(...) function is fully documented, you can check the description to know what other options you have.

Do a multiple files delete (this will use the cloudinary delete resources method)

    final response = await cloudinary.deleteFiles(
        urls: urlPhotos,
        resourceType: CloudinaryResourceType.image
      );
    if(response.isSuccessful ?? false){
      Map<String, dynamic> deleted = response.deleted;//in deleted Map you will find all the public ids and the status 'deleted'
    }

To delete multiple cloudinary files it´s necessary a list of public_id's, as you can see in the sample code the deleteFiles(...) function can delete files from a list of urls... You can also pass an optParams map to do a more elaborated delete according to https://cloudinary.com/documentation/admin_api#delete_resources The cloudinary.deleteFiles(...) function is fully documented, you can check the description to know what other options you have.

Load an Image from cloudinary with some transformations

    final cloudinaryImage = CloudinaryImage(urlPhotos[index]);
    String transformedUrl = cloudinaryImage.transform().width(256).height(256).thumb().face().opacity(30).angle(45).generate();
    return Image.network(transformedUrl);

Note:

It's recommended to check the example code for a better idea of how to work with this plugin.
