Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

pdf_merger is a Flutter plugin that enables merging multiple PDF files into a single document on both Android and iOS platforms. It provides a straightforward API to combine PDFs programmatically, making it ideal for apps requiring document consolidation. Users must grant file permissions and integrate a file picker before using the plugin, as noted in the example. The package is lightweight and designed for seamless integration with existing Flutter projects.

Use cases

  • Merge multiple PDFs from user selection
  • Combine reports or forms into one file
  • Support document processing workflows

  • Automate PDF aggregation in apps
  • Enable offline PDF management

Key features

  • Cross-platform support (Android & iOS)

  • Lightweight and efficient

Suitable for

Considerations
