How to delete local database while uninstalling the flutter windows application? - flutter

Question

I am using the DRIFT package (formerly known as MOOR) for local database and I want to delete the database file, when uninstalling the windows application, which is saved in local machine (Windows) as db.sqlite. How can I achieve this?
Drift package for database. Drift documentation. Drift code :
// These imports are only needed to open the database
import 'dart:io';
import 'package:drift/drift.dart';
import 'package:drift/native.dart';
import 'package:path_provider/path_provider.dart';
import 'package:path/path.dart' as path;
import 'package:summa_app/database/program_location/program_location_dao.dart';
import 'package:summa_app/database/program_location/program_location_table.dart';
import 'package:summa_app/database/programs/program_dao.dart';
import 'package:summa_app/database/programs/program_table.dart';
part 'summa_database.g.dart';
#DriftDatabase(tables: [ProgramLocation, DbPrograms], daos: [ProgramLocationDao, ProgramsDao])
class SummaDatabase extends _$SummaDatabase {
// we tell the database where to store the data with this constructor
SummaDatabase() : super(_openConnection());
// you should bump this number whenever you change or add a table definition.
// Migrations are covered later in the documentation.
#override
int get schemaVersion => 1;
#override
Future<void> close() async{
await _openConnection().close();
return super.close();
}
}
LazyDatabase _openConnection() {
// the LazyDatabase util lets us find the right location for the file async.
return LazyDatabase(() async {
// put the database file, called db.sqlite here, into the documents folder
// for your app.
final dbFolder = await getApplicationDocumentsDirectory();
final file = File(path.join(dbFolder.path, 'db.sqlite'));
return NativeDatabase(file);
});
}

There are two options here:
You could close the database, delete the file from the device, and then re-open it.
You can delete everything from all tables, without closing the database:
Future<void> deleteEverything() {
return transaction(() async {
// you only need this if you've manually enabled foreign keys
// await customStatement('PRAGMA foreign_keys = OFF');
for (final table in allTables) {
await delete(table).go();`enter code here`
}
});
}
