Flutter fetch nested future - flutter

Question

I have a method that fetches a PatientLog from SQLite.However, This PatientLog table mapped to an object with a class named PatientLog. Inside this PatientLog class, several other objects such as Speciality, AttendingPhysician, Course, etc. I need to map these PatienLog records to a local object. However, I have to use nested Futures. I need to retrieve the data from this nested Future. Think of Future of Future.
This is my fetch method
Future<List<Future<PatientLog>>> getForms() async {
Database db = await instance.getDatabase;
List<Map<String, dynamic>> forms =
await db.query(_tablePatientLog, orderBy: 'id DESC');
Institute? institute;
AttendingPhysician? attendingPhysician;
Speciality? speciality;
Course? course;
List<Future<PatientLog>> list = forms.map((myMap) async {
int? courseId = myMap['course_id'] as int?;
int? specialityId = myMap['speciality_id'] as int?;
int? attendingId = myMap['attending_id'] as int?;
int? instituteId = myMap['institute_id'] as int?;
if (courseId != null) {
await getCourse(courseId).then((value) => course=value);
}
if (attendingId != null) {
await getAttending(attendingId).then((value) => attendingPhysician=value);
}
if (specialityId != null) {
await getSpeciality(specialityId).then((value) => speciality=value);
}
if (instituteId != null) {
await getInstitute(instituteId).then((value) => institute=value);
}
return PatientLog.fromMap(
myMap, institute, course, attendingPhysician, speciality);
}).toList();
return list;
}
I need to display that information on a screen. I get an error type 'List<Future<PatientLog>>' is not a subtype of type 'Future<Object?>?'
class _DraftsState extends State<Drafts> {
final SQFLiteHelper _helper = SQFLiteHelper.instance;
#override

_refresh();
}
late List<Future<PatientLog>> fromDatabase;
Future<dynamic> _refresh() async {
await _helper.getForms().then((value) async{
setState(() {
fromDatabase = value;
});
});
}
