Nutrient Flutter SDK

Flutter plugin wrapping the native Nutrient iOS and Android SDKs. Provides PDF viewing, annotation, form filling, and digital signing from a single Dart API, plus a real-time collaboration variant via Nutrient Instant.

Documentation

Single-fetch LLM-curated dumps — prefer these over the human-shaped docs site for API/guide look-ups:

Example Repositories

• Official Flutter plugin: https://github.com/PSPDFKit/pspdfkit-flutter

Key Concepts

• Package: flutter pub add nutrient_flutter. The legacy pspdfkit_flutter package is the pre-rebrand name; new projects use nutrient_flutter.
• Main widget: NutrientView — embeds the PDF viewer inline. Use NutrientInstantView instead when you need real-time collaborative annotation via Nutrient Instant. The legacy PspdfkitWidget is the pre-rebrand name.
• Required initialisation: call Nutrient.initialize(androidLicenseKey: ..., iosLicenseKey: ...) in main() before runApp(). The SDK refuses to work without initialize() having been called — this requirement is new in the Nutrient era; the legacy pspdfkit_flutter plugin auto-initialised.
