Last updated: Dec-04-2024
When using the Flutter SDK, you can use one of several options to upload files directly to Cloudinary without the need for server-side operations or authentication signatures.
Upload options
Upload endpoint
The upload endpoint is https://api.cloudinary.com/v1_1/<CLOUD_NAME>/upload
. To use the endpoint in your application, write a function that calls the Cloudinary upload
endpoint and pass:
- An unsigned upload preset with the upload method options you want to apply for all files
- The file(s) to upload
- Other unsigned upload parameters to apply to the selected files (e.g.
tags
, if needed).
For example:
Upload endpoint video tutorial
Watch this video tutorial to see how to upload images from your Flutter app to Cloudinary using the Upload API:
Tutorial contents
Upload widget
The Upload widget is a ready-made, responsive user interface that enables your users to upload files from a variety of sources directly to Cloudinary. You can customize and embed this UI in a WebView Flutter widget with just a few lines of code.
Check out the following Upload Widget code explorer that you can fork to try out some sample configuration changes:
This code is also available in GitHub.
Code examples
- Code sample: Implement the upload widget.
- CodeSandbox: Upload multiple files using a form in pure JavaScript using the Cloudinary upload endpoint.
