cktap_transport 0.0.1

cktap_transport: ^0.0.1 copied to clipboard

Provides interfaces for NFC operations required by the cktap_protocol plugin. Using a separate package allows the protocol plugin to be decoupled from specific NFC plugins. It also means the user can provide their own implementation.

Features #

• Transport base class
• TransportException base class

Getting started #

Add one of the following dependencies to your pubspec.yaml:

dependencies:
  # Only when implementing your own transport class
  cktap_transport: ^0.0.1

  # An implementation using the nfc_manager plugin
  cktap_transport_nfc_manager: ^0.0.1

Usage #

Here's an example of implementing your own transport function:

import 'dart:typed_data';

import 'cktap_transport/cktap_transport.dart';

/// Implement the sendBytes function
class MyTransport extends Transport {
  @override
  Future<Uint8List> sendBytes(Uint8List bytes) async {
    try {
      // Send data here and return the response as bytes
    }
    catch (_) {
      throw const MyTransportException();
    }
  }
}

/// Create an exception
class MyTransportException implements TransportException {
  const MyTransportException();

  @override
  String toString() => "blah";
}

Additional information #

Concrete implementations exist for the following plugins:

• nfc_manager v3.3.0
  • v4.0.0 will bring breaking changes so it will need updating
