channel getConnection()

[Firemanpl]

I want to detect lost connection or not connection or failed connection. I found method channel.getConnection(), but It return object which returns useless method like shutdown etc. My question is simply. How to detect connection loss or connection failure and successful channel connection to the server ? It is possible ?. I found keepalive method on channel but it it gives me little to maintain the connection without any method that checks this connection.

class GrpcManager {
  late ClientChannel channel;
  //late MetadaztaClient stub;
  Future<void> connect(List<String> args) async {
    channel = ClientChannel(
      '127.0.0.1',
      port: 8080,
      options: const ChannelOptions(
        credentials: ChannelCredentials.insecure(),
        keepAlive: ClientKeepAliveOptions(
          pingInterval: Duration(seconds: 1),
          timeout: Duration(seconds: 10),
          permitWithoutCalls: true,
        ),
      ),
    );
    // stub = MetadataClient(channel);
    final clientConnection = await channel.getConnection();
    if (clientConnection.) {}
    await channel.shutdown();
  }
}
