如何在Flutter中为使用itemBuilder生成的列表中的每个项目分配不同的关键点？

class Project {
  final String id;
  final String name;

  Project({required this.id, required this.name});
}

List<Project> projects = [
  Project(id: '1', name: 'Project 1'),
  Project(id: '2', name: 'Project 2'),
  Project(id: '3', name: 'Project 3'),
];

ListView.builder(
  itemCount: projects.length,
  itemBuilder: (BuildContext context, int index) {
    Project project = projects[index];
    String keyPoint;

    switch (project.id) {
      case '1':
        keyPoint = 'Key point for Project 1';
        break;
      case '2':
        keyPoint = 'Key point for Project 2';
        break;
      case '3':
        keyPoint = 'Key point for Project 3';
        break;
      default:
        keyPoint = 'Default key point';
    }

    return ListTile(
      title: Text(project.name),
      subtitle: Text(keyPoint),
    );
  },
);
