Error first time running build_runner

[DanBaDo]

Hi!
I'm trying to use Drift for first time.
I'm following Drift web setup documentation.
When I try to run build_runner, I got a warning about three errors and database.g.dart is not created:

• database.dart:22:24: A class declaration must have a body, even if it is empty.
• database.dart:22:25: Expected a method, getter, setter or operator declaration.
• database.dart:22:26: Functions must have an explicit list of parameters.

This is my code:

import 'dart:io';

import 'package:drift/drift.dart';
import 'package:drift/native.dart';

import 'package:path/path.dart' as path;

part 'database.g.dart';

@DataClassName('TodoCategory')
@TableIndex(name: 'user_email', columns: {#email})
@TableIndex(name: 'user_uuid', columns: {#uuid})
class UserTable extends Table {
  TextColumn get uuid => text().withLength(min: 37, max: 37).unique()();
  TextColumn get email => text().unique()();
  BoolColumn get enabled => boolean().withDefault( const Constant(true))();
  @override
  Set<Column> get primaryKey => {uuid};
}

@DriftDatabase(tables: [UserTable])
class Database extends _&Database {}

I can't see what I'm doing wrong.

_&Database looks wrong. Probably should be _$Database. Also better give your Database class a prefix so it doesn't clash with other classes called Database. class FooDatabase extends _$FooDatabase {}

Oh, my!
Thank you, very, very much, and sorry about.
I've lost a few hours because of the &.
Thank you.
