A pure Dart implementation of the Datecs Fiscal Device Communication Protocol.
This package allows Flutter and Dart applications to communicate directly with Datecs fiscal devices without relying on native platform code.

Features

• 🔌 Works across mobile, desktop, and embedded Dart runtimes
• 🧾 Support for sending fiscal commands and parsing device responses
• 🛠️ Extensible API for custom Datecs protocol commands
• ⚡ Includes a partial implementation for one device model, but designed so you can easily extend or define your own devices and commands

🚧 Limitations

• Not all Datecs commands are currently implemented
• Only one device model is partially supported out of the box
• You can extend the package with custom device definitions or additional commands as needed
