Dart quick start

Last updated: Mar-20-2024

This quick start lets you get an end-to-end implementation up and running using the Dart SDK in 5 minutes or less.

1. Set up and configure the SDK

Install the package

Install the @cloudinary_url_gen package by adding Cloudinary as a dependency in your pubspec.yaml file.

Configure Cloudinary

When writing your own applications, follow your organization's policy on storing secrets and don't expose your API secret.

Within your main.dart file, use your API environment variable to configure your credentials (replace cloudinary://my_key:my_secret@my_cloud_name below with your environment variable value):


2. Upload an image

Copy and paste this into main.dart:

main.dart (continued)

3. Transform and deliver the image

Displaying the full image URL based on the specified transformation parameters:

Copy and paste the following code, under the configuration code:

main.dart (continued)

If you followed the steps to upload the docs/models asset, you might want to use that public ID instead of cld-sample. If you're using an image with a public ID other than cld-sample, make sure to update your code for the remainder of this quick start with the public ID of the image you're delivering.

4. Run your code

Run the code to see the transformed image.
