Integrating Real-Time Collaboration into Your Flutter Application

PSPDFKit Instant for Flutter makes it easy to add real-time collaboration features to your PSPDFKit-powered app. It allows users to seamlessly share, edit, and annotate PDF documents across Android, iOS, and web apps.


PSPDFKit for Flutter with Instant

PSPDFKit for Flutter supports Instant by default. No additional setup is required on the client side. To run Instant, provide the server URL and the JSON Web Token (JWT) from the server, which contains the user authentication, permissions, and Instant layers.
