What is a Flutter PDF SDK?
A Flutter PDF SDK is a software development kit that enables developers to integrate PDF viewing, editing, and management capabilities into Flutter applications. It allows for the creation, modification, and rendering of PDF documents within both iOS and Android platforms from a single codebase.
Is the SDK compatible with both iOS and Android platforms?
Yes. The Nutrient Flutter PDF SDK is designed for cross-platform compatibility, allowing developers to deploy PDF functionality seamlessly on both iOS and Android devices from a single Flutter codebase.
Does the SDK support offline access to PDF documents?
Absolutely. The SDK enables offline access to PDF documents, allowing users to view and interact with PDFs without an active internet connection.
Can I customize the user interface of the PDF viewer?
Yes. The SDK provides extensive customization options for the PDF viewer’s user interface, enabling developers to tailor the appearance and functionality to align with their application’s design and user experience requirements.
How does the SDK handle large PDF files?
The Nutrient Flutter PDF SDK is optimized for performance, ensuring smooth loading and navigation, even with large PDF files. Features like lazy loading and efficient memory management contribute to handling extensive documents effectively.
Is there support for real-time collaboration on PDF documents?
While the SDK offers robust annotation and editing tools, implementing real-time collaboration requires additional backend support to manage concurrent user interactions. Developers can integrate this functionality depending upon their application’s architecture and requirements.
