                          textAlign: TextAlign.left,
                        maxLines: 100,
                        overflow: TextOverflow.ellipsis,
                        ),
                    ),

                  ),
                    SizedBox(width: 5,),
                  ],
                ),
                ),
              ),
              ...
            ],
          ),
        ],
      ),
      ),
    ),
  ],
);
