onDeactivated property

set onDeactivated (void handler(int reason)?)

The link to the reader ended.

The reason is Android's HostApduService constant: 0 when the link was lost, 1 when the reader selected a different application.

Implementation

set onDeactivated(void Function(int reason)? handler) {
  NfcCallbacks.instance.hceDeactivatedHandler = handler;
}
