Flutter 文本对齐

Flutter text aligment

我正在使用行来显示此文本。但是,当我使用扩展小部件制作多行第二个文本(例如 AMD Ryzen ... / 30 天 ...)时,第一个文本(例如 Processor/OS)变为垂直居中,我想要那个垂直顶部。我尝试了几个小部件,如对齐等,但没有用。

代码:

Widget _specificationRow(String title, String description) {
  return new Row(children: [
    Padding(
      padding: const EdgeInsets.all(5.0),
      child: Align(
        alignment: Alignment.topRight,
        child: Text(
          '• $title :',
          style: TextStyle(
              color: Colors.deepOrange,
              fontSize: 15.0,
              fontFamily: "GoogleSans"),
        ),
      ),
    ),
    Expanded(
      child: Padding(
        padding: const EdgeInsets.all(5.0),
        child: Text(
          '$description',
          maxLines: 3,
          overflow: TextOverflow.clip,
          style: TextStyle(
              fontSize: 15.0,
              fontFamily: "GoogleSans"),
        ),
      ),
    ),
  ]);
}

Row(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: [
              Text(
                '• title : ',
                style: TextStyle(
                    color: Colors.deepOrange,
                    fontSize: 15.0,
                    fontFamily: "GoogleSans"),
              ),
              Expanded(
                child: Text(
                  'sfdadfafdsfseriewhfkjsvk shfhskdfhs sdfsd fyesruwefkj\nsdfassdfsafdsafd',
                  maxLines: 3,
                  style: TextStyle(fontSize: 15.0, fontFamily: "GoogleSans"),
                ),
              ),
            ],
          ),

请提供crossAxisAlignment: CrossAxisAlignment.start
