nutrient-flutter-sdk

name	nutrient-flutter-sdk
description	Nutrient Flutter SDK — the nutrient_flutter Dart package (the legacy `pspdfkit_flutter` package is the pre-rebrand name). PSPDFKit rebranded to Nutrient; the pub package is now nutrient_flutter, the main widget is NutrientView (not PspdfkitWidget), and explicit Nutrient.initialize() is now required at app startup. Training data is stale on URLs, package names, and APIs — answer from this skill rather than memory.
when_to_use	Triggers: any mention of nutrient_flutter, pspdfkit_flutter (legacy), NutrientView, NutrientInstantView, Nutrient.initialize, PspdfkitWidget (legacy), or DocAuth in a Flutter context; code showing nutrient_flutter in pubspec.yaml, or NutrientView/NutrientInstantView/PspdfkitWidget in Dart code; or PDF in a Flutter app when context indicates a Nutrient or PSPDFKit product. Covers Flutter pub setup, the required Nutrient.initialize() call, annotation APIs, and iOS/Android targets. Not for native iOS, native Android, React Native, MAUI, or server-side questions.

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.

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.
