app database generated file having errors in moor flutter - flutter

Question

I am using moor package in flutter for my application. im following the instructions online
https://moor.simonbinder.eu/docs/getting-started/starting_with_sql/#what-moor-generates
but when i run the build command: flutter pub run build_runner build
the appdatabase.g.dart file that gets generated has errors. here is a snapshot of errors:
here is my dependencies
cupertino_icons: ^0.1.2
month_picker_dialog: ^0.3.1
flutter_cupertino_localizations: ^1.0.1
moor: ^2.3.0
provider: ^4.0.3
moor_ffi: ^0.4.0
path_provider: ^1.6.0
dev_dependencies:
flutter_test:
sdk: flutter
intl_translation: ^0.17.1
moor_generator: ^2.3.1
build_runner:
the problem seems to be with 'Table' class. there is a conflict between dart and moor. the message indicate there are two versions. how can i solve this problem so that my error goes away

Answer 1

the answer is to use import 'package:flutter/widgets.dart' hide Table;

Answer 2

dependencies:
flutter:
sdk: flutter
#moor database
moor_flutter: ^3.1.0
# For the UI
provider: ^4.3.1
# For OS-specific directory paths
path_provider: ^1.6.11
cupertino_icons: ^0.1.3
dev_dependencies:
flutter_test:
sdk: flutter
#new Dependencies add
moor_generator: ^3.2.0
build_runner:
Step 1 : delete file appdatabase.g.dart
step 2: flutter clean
Step 3: flutter pub get
Step 4: flutter pub run build_runner build watch

Answer 3

This error occurs when you don't have the 'import' of your table or dao in your AppDb class, in my case I have more than 90 tables and dao's, I separated then in a class with a static list, but I need do the imports of my files in the app_database.dart too, because of the error.
I have this class for tables:
import '../tables/table_one.dart';
import '../tables/table_two.dart';
class TableList {
static const List<Type> tables = [
TableOne,
TableTwo,
]
}
And another for Dao files:
import '../dao/table_one_dao.dart';
import '../dao/table_two_dao.dart';
class DaoList{
static const List<Type> daos= [
TableOne,
TableTwo,
]
}
And this is my AppDb class:
import '../tables/table_one.dart';
import '../tables/table_two.dart';
import '../dao/table_one_dao.dart';
import '../dao/table_two_dao.dart';
part 'app_db.g.dart';
#DriftDatabase(
tables: TableList.tables,
daos: DaoList.daos,
)
class AppDb extends _$AppDb {
AppDb() : super(_openConnection());
#override
int get schemaVersion => 1;
}
LazyDatabase _openConnection() {
return LazyDatabase(() async {
final dbFolder = await getApplicationDocumentsDirectory();
final file = File(p.join(dbFolder.path, 'app_database.db'));
return NativeDatabase(file);
});
}
As you see, i have to declare the imports again in my AppDb file to resolve. If you declare your tables directly in the AppDb escope, i think you don't have problem.
