Overview
The ndef package is a Dart library designed to decode and encode NDEF (NFC Data Exchange Format) records, enabling seamless interaction with NFC tags across multiple platforms. It supports various NDEF record types, making it ideal for applications involving contactless data exchange. Built with security in mind, it aligns well with cryptographic and permission-based workflows. The library is compatible with Android, iOS, Web, macOS, Windows, and Linux, offering broad cross-platform functionality for NFC-enabled apps.
