Nutrient Flutter SDK web PDF viewer

Nutrient Flutter SDK includes a PDF rendering engine for web apps. You can embed a configurable PDF viewer in web, iOS, or Android applications from a single codebase.

Review key capabilities

Nutrient Flutter SDK supports the following viewer capabilities:

• Configurable UI — Hide or add buttons and match your app design.
• Client-side processing — Run processing on the client without a server.
• PDF and image viewing — Open PDF, TIFF, PNG, and JPG files.
• Accessibility features — Use built-in features for assistive technologies.
• Document tools — Add annotations, editing tools, and forms.

Check PDF file type support

Nutrient Flutter SDK supports the following file types:

• PDF
• TIFF (multipage)
• JPG
• PNG

Choose CDN or self-hosted asset loading

By default, Nutrient Flutter SDK loads the Nutrient Web SDK assets from a content delivery network (CDN). To self-host the assets, set useCDN to false in a WebViewConfiguration. Pass WebViewConfiguration as the configuration’s webConfig. Self-host assets when you’re in an air-gapped environment or need to comply with Content Security Policies.

NutrientDocumentView(
  documentPath: 'path/to/document.pdf',
  configuration: NutrientViewConfiguration(
    webConfig: WebViewConfiguration(
      useCDN: false,
    ),
  ),
)

When you set useCDN to false, the SDK loads assets from local paths instead of the CDN. Setting baseUrl to a custom asset location overrides useCDN.

You can also use the useCDN option in WebViewConfiguration with NutrientInstantView.
