Use Case
The C72 RFID Flutter Plugin was built for industrial use cases where Flutter applications need to access the RFID hardware on Chainway C72 devices — specialized Android handhelds widely used in logistics and asset management. The plugin eliminates the need to write separate native Java/Kotlin code, exposing full RFID reader control through an idiomatic Dart API.
Key Features
- Reader initialization & release — full lifecycle control of the RFID reader from Dart
- Single & bulk tag reading — supports both single scan and continuous scan modes for rapid inventory operations
- Stream-based API — tag read results are delivered via a Dart
Stream, making integration with any state management solution straightforward - Structured error handling — SDK error codes are mapped to descriptive Dart exceptions for clean error propagation
Technical Challenges
The core challenge was mapping the synchronous API of the Chainway C72 SDK (Java) to the asynchronous, reactive model expected by Flutter developers. The solution uses an EventChannel for continuously streaming incoming tag data, and a MethodChannel for one-off operations like initialization and configuration.
