【问题讨论】：

将您的小部件包装在扩展或灵活小部件中，它应该可以工作

标签： flutter flutter-layout flutter-web flutter-animation flutter-test

【解决方案1】：

将您的小部件包装在 Expanded 或 Flexible：

Row(
    crossAxisAlignment: CrossAxisAlignment.start,
    children: [
      Image.network(
        'https://miro.medium.com/max/1400/1*-6WdIcd88w3pfphHOYln3Q.png',
        width: 100,
      ),
      SizedBox(
        width: 10,
      ),
      Expanded(
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            Text(
              ' {widget.eventsListDetails[index][ name ]}',
            ),
            Text(
              " {widget.eventsListDetails[index]['description']}{widget.eventsListDetails[index]['description']}{widget.eventsListDetails[index]['description']}{widget.eventsListDetails[index]['description']}",
              overflow: TextOverflow.ellipsis,
              maxLines: 3,
            ),
          ],
        ),
      ),
    ],
  ),

尝试通过将文本包装在 SizedBox 中并为其设置固定宽度来限制文本的宽度。

      SizedBox(
        width: 200,
        child: Text(
          "${widget.eventsListDetails[index]['description']}",
          style: GoogleFonts.poppins(fontSize: 12, color: Color(0xff444444)),
          overflow: TextOverflow.ellipsis,
          maxLines: 2,
        ),
      ),

用 Expanded/Flexible 小部件包装列。

Expanded(
                      child: Column(
                        crossAxisAlignment: CrossAxisAlignment.start,
                        children: [
                          Text(
                            '${widget.eventsListDetails[index]['name']}',
                            style: GoogleFonts.poppins(
                                fontSize: 14, color: Color(0xff158998)),
                          ),
                          Text(
                            "${widget.eventsListDetails[index]['description']}",
                            style: GoogleFonts.poppins(
                                fontSize: 12, color: Color(0xff444444)), overflow: TextOverflow.ellipsis,

使用这个

             Column(
                      crossAxisAlignment: CrossAxisAlignment.start,
                      children: [
                        Text(
                          '${widget.eventsListDetails[index]['name']}',
                          style: GoogleFonts.poppins(
                              fontSize: 14, color: Color(0xff158998)),
                        ),
                        Expanded(
                       Text(
                        "${widget.eventsListDetails[index]['description']}",
