UI — Attendance Marking

Uses sticky_grouped_list for scrollable student list grouped by first letter:

class AttendanceScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final vm = context.watch<AttendanceViewModel>();
    final authVM = context.watch<AuthViewModel>();

    // Disabled in evaluation mode
    if (authVM.isEvaluationMode) {
      return const ReadOnlyAttendanceView();
    }

    return Scaffold(
      body: StickyGroupedListView<Student, String>(
        elements: vm.students,
        groupBy: (s) => s.name[0],  // Group by first letter
        groupSeparatorBuilder: (s) => Text(s.name[0], style: const TextStyle(fontWeight: Bold)),
        itemBuilder: (_, student) => StudentAttendanceTile(
          student: student,
          onStatusChanged: (status) => vm.setStatus(student.id, status),
        ),
      ),
      floatingActionButton: FloatingActionButton.extended(
        onPressed: vm.canSubmit ? () => vm.submitAttendance() : null,
        label: const Text('Submit Attendance'),
      ),
    );
  }
}

Mark All Present

void markAllPresent() {
  for (final student in students) {
    vm.setStatus(student.id, 'PRESENT');
  }
}
