如何在Flutter中解析列表中的列表？

class Student {
  String name;
  int age;
  List<String> courses;

  Student({this.name, this.age, this.courses});
}

List<Student> students = [
  Student(
    name: "Alice",
    age: 20,
    courses: ["Math", "Science"],
  ),
  Student(
    name: "Bob",
    age: 22,
    courses: ["English", "History"],
  ),
];

ListView.builder(
  itemCount: students.length,
  itemBuilder: (context, index) {
    Student student = students[index];
    return ListTile(
      title: Text(student.name),
      subtitle: Text("Age: ${student.age}"),
      trailing: Column(
        children: student.courses.map((course) => Text(course)).toList(),
      ),
    );
  },
)
