DatabaseView from Entities

[robotoss]

Hello
I have 3 table
A:

const gameTableName = 'games';

@Entity(tableName: gameTableName)
class Game {
  const Game({
    required this.id,
    required this.alias,
    required this.name,
  });

  @primaryKey
  final String id;
  final String alias;
  final String name;
}

B:

const gamesCategoriesTableName = 'games_categories';

@Entity(tableName: gamesCategoriesTableName)
class GamesCategory {
  const GamesCategory({
    required this.id,
    required this.name,
    required this.alias,
  });

  @primaryKey
  final String id;
  final String name;
  final String alias;
}

C:

const gamesInCategoryTableName = 'game_in_categories';

@Entity(
  tableName: gamesInCategoryTableName,
  foreignKeys: [
    ForeignKey(
      childColumns: ['categoryId'],
      parentColumns: ['id'],
      entity: GamesCategory,
    ),
    ForeignKey(
      childColumns: ['gameId'],
      parentColumns: ['id'],
      entity: Game,
    ),
  ],
)
class GameInCategory {
  const GameInCategory({
    this.id,
    required this.order,
    required this.categoryId,
    required this.gameId,
  });

  @PrimaryKey(autoGenerate: true)
  final int? id;
  final int order;
  final String categoryId;
  final String gameId;
}

I write:

@DatabaseView(
  '''
    SELECT
        gic.order as order,
        gc.*,
        g.*
    FROM
        $gamesInCategoryTableName as gic
    INNER JOIN
        category as gc ON gic.categoryId = gc.id
    AS game INNER JOIN
        game as g ON gic.gameId = g.id
    ''',
  viewName: 'game_with_category',
)
class GameWithCategory {
  const GameWithCategory({
    required this.category,
    required this.order,
    required this.game,
  });

  final int order;
  final GamesCategory category;
  final Game game;
}

@Database(
  version: 1,
  views: [GameWithCategory],
  entities: [GamesCategory, Game, GameInCategory],
)
abstract class AppDatabase extends FloorDatabase {
  GamesCategoriesDao get gamesCategoriesDao;

  GamesDao get gamesDao;

  GameInCategoryDao get gameInCategoryDao;
}

But on generation I have errors:

Column type is not supported for GamesCategory.
Column type is not supported for Game.

How can I get class for use with DAO like this:

  @Query('SELECT * FROM game_with_category')
  Future<List<GameWithCategory>> getGamesWithCategory();
