Answer 1

解决方案：在 Row 小部件中添加三个 Flexible 小部件 ;)

if (root.children.isEmpty) {
      return ListTile(
        title: Text(root.title),
        subtitle: root.subtitle == null ? null : Text(root.subtitle!),
        trailing: Row(
          mainAxisSize: MainAxisSize.min,
          children: [
            Flexible(
              child: IconButton(
                onPressed: () {},
                icon: const Icon(Icons.auto_stories),
                iconSize: 30,
                tooltip: 'Documents',
              ),flex: 1,
            ),
            Flexible(
              child: IconButton(
                onPressed: () {},
                icon: const Icon(Icons.video_collection_rounded),
                iconSize: 30,
                tooltip: 'Videos',
              ),
              flex: 1,
            ),
            Flexible(
              child: IconButton(
                onPressed: () {},
                icon: const Icon(Icons.favorite),
                iconSize: 20,
                tooltip: 'Shortlist',
              ),flex: 1,
            ),
          ],
        ),
      );
    }
