User Richtext with TextSpan in container but is not its not gives proper output

I used RichText and TextSpan for my formatted string. But issue is I want long string with ... form

I do some RnD, As per some solutions on google I use Expanded and Flexible widget also but not get output even when i user Expanded or Flexible string will be vanished.

Screenshot of what I want,

And Screenshot of my output

Instead of long string with ... at the end within a container, The string overlapping the container and show that UI warning

My Code is

            child: Column(
              children: [
                Visibility(
                  visible: notificationList[index].isHeader ? false : true,
                  child: Container(
                    margin: EdgeInsets.fromLTRB(
                        1, notificationList[index].isHeader ? 0 : 15, 1, 0),
                    padding: EdgeInsets.all(10),
                    decoration: BoxDecoration(
                      borderRadius: BorderRadius.all(
                        Radius.circular(10.0),
                      ),
                      color: Colors.white,
                      boxShadow: [
                        BoxShadow(
                          color: Colors.grey,
                          blurRadius: 3,
                          offset: Offset(0, 0), // Shadow position
                        ),
                      ],
                    ),
                    child: Row(
                      children: [
                        Container(

                          ),
                        ),
                        Column(
                          crossAxisAlignment: CrossAxisAlignment.start,
                          children: [
                            Container(

                              child: Flexible(

                                    maxLines: 1,
                                    text: TextSpan(
                                      style: const TextStyle(
                                        fontSize: 15.0,
                                        color: Colors.black,
                                      ),
                                      children: <TextSpan>[
                                        TextSpan(
                                            text:
                                                '${notificationList[index].title}',
                                            style: const TextStyle(
                                                fontWeight: FontWeight.bold)),
                                        TextSpan(
                                            text:
                                                ' (${notificationList[index].name})'),
                                      ],
                                    )),
                              ),
                            ),
                          ],
                        ),
                      ],
                    ),
                  ),
                ),
              ],
            )

The flexible widget has to be the first child of the row for it to identify how much it will extend and remove the softwrap so there is no line break. I also removed the columns and left only the visibility.

Visibility(
  visible: notificationList[index].isHeader ? false : true,
  child: Container(
    margin: EdgeInsets.fromLTRB(
        1, notificationList[index].isHeader ? 0 : 15, 1, 0),

        Radius.circular(10.0),

      boxShadow: [
        BoxShadow(
          color: Colors.grey,
          blurRadius: 3,
          offset: Offset(0, 0), // Shadow position
        ),
      ],
    ),
    child: Row(
      children: [
