Installing the Nutrient dependency

You can load Nutrient Web SDK directly from Nutrient’s content delivery network (CDN). Nutrient maintains the CDN for customers, and it’s our recommended way to get started. For more control and flexibility, use the local installation option.

  1. Add the following script tag to the <head> section of your web/index.html file:

    <script src="https://cdn.cloud.pspdfkit.com/pspdfkit-web@1.9.1/nutrient-viewer.js"></script>

  2. You’re now ready to use Nutrient Web SDK and reference window.NutrientViewer in the client-side code.

Rendering a PDF

  1. Import the PSPDFKit package:

    import 'package:nutrient_flutter/nutrient_flutter.dart';

  2. Display a PDF document inside your Flutter app:

    Scaffold(
      body: NutrientView(
        documentPath: 'https://www.nutrient.io/downloads/nutrient-web-demo.pdf',
      ),
    );

  3. Run the app:

    Terminal window
    flutter run
