Nutrient Flutter SDK web PDF viewer

Nutrient Flutter SDK includes a PDF rendering engine that’s compatible with web apps. It enables developers to embed a configurable PDF viewer in web, iOS, or Android applications from a single codebase.

Key capabilities

• Customizable UI — Hide or add buttons and match your app design
• Client-side — Offloads processing to the client (no server needed)
• PDF and image — Open PDF, TIFF, PNG, and JPG files
• Accessible — Built-in assistive technology-friendly features
• Extendable — Add annotations, editing, and forms

PDF file type support

• PDF
• TIFF (multipage)
• JPG
• PNG

Asset loading: CDN vs. self-hosted

By default, Nutrient Flutter SDK loads the Nutrient Web SDK assets from a CDN. To self-host the assets — for example, in air-gapped environments or to comply with content security policies — set useCDN to false in PdfWebConfiguration:

NutrientView(
  documentPath: 'path/to/document.pdf',
  configuration: PdfConfiguration(
    webConfiguration: PdfWebConfiguration(
      useCDN: false,
    ),
  ),
)

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

The useCDN option is also available in WebViewConfiguration for use with NutrientInstantView.
