推荐答案

这是一个小功能，可以为您完成此操作，然后返回小部件列表.

This is a small function that would do that for you then returns a list of widgets.

List<Text> _transformWord(String word) {
    List<String> name = word.split(' ');
    List<Text> textWidgets = [];
    for (int i = 0; i < name.length; i++) {
      if (name[i].contains('@')) {
        Text bold = Text(
          name[i] + ' ',
          style: TextStyle(
            fontWeight: FontWeight.bold,
          ),
        );
        textWidgets.add(bold);
      } else {
        Text normal = Text(
          name[i] + ' ',
        );
        textWidgets.add(normal);
      }
    }
    return textWidgets;
  }

您将从行小部件中调用此函数

You would call this function from a row widget

Row(
     children: _transformWord(),
    ),
