flutter 的即时通讯 在测试环境正常，打包后不能发送消息

openjdk version "1.8.0_242-release" ，测试机用debug包没问题，网络肯定没问题

      AVIMClient client = StringUtil.isEmpty(tag) ?
      AVIMClient.getInstance(clientId) : AVIMClient.getInstance(clientId, tag);
  client.open(openOption, new AVIMClientCallback() {
    @Override
    public void done(AVIMClient client, AVIMException e) {
      Log.d(TAG, "client open result: " + Common.wrapClient(client));
      if (null != e) {
        Log.d(TAG, "test1");
        result.success(Common.wrapException(e));
      } else {
        Log.d(TAG, "test2");
        result.success(Common.wrapSuccessResponse(Common.wrapClient(client)));
      }
    }
  });
  return;
}

我定位到test1这个地方了，再里面没跟踪

没有做，新初始化的项目
