Sqlflite table does not exist

I am new with flutter, so let me know if I am missing anything. I have the folowing situation:

I am trying to create the table entity. The problem happens when I try to retrieve the data, I get an error saying that the table does not exist. This error does not happen when I insert into the same table. It is obvious that the table is not being created, so I would like to know what I am doing wrong on the creation.

Additionally, as the error is only being shown when I retrieve and not when I insert, I am curious about that. So, can someone explain me about this, like why it happens?

Below I am leaving the code that I think is necessary, please let me know if something else is needed.

Future<Database> createDatabase() {
  return getDatabasesPath().then((dbPath) {
    final String path = join(dbPath, "generic-app.db");
    return openDatabase(path, onCreate: (db, version) {
      db.execute("CREATE TABLE entity ("
          "id INTEGER PRIMARY KEY"
          "titulo VARCHAR,"
          "subtitulo VARCHAR"
          ")");
    }, version: 1);
  });
}

The save() method that insert into the table:

Future<int> save(Entity entity) {
  return createDatabase().then((db) {
    final Map<String, dynamic> mapEntity = Map();
    mapEntity['id'] = entity.id;
    mapEntity['titulo'] = entity.titulo;
    mapEntity['subtitulo'] = entity.subtitulo;

    return db.insert("entity", mapEntity);
  });
}

The findAll() method that is throwing the exception:

Future<List<Entity>> findAll() {
 return createDatabase().then((db) {
    return db.query("entity").then((maps) {
      List<Entity> entities = List.empty(growable: true);
      for (Map<String, dynamic> map in maps) {
        Entity entity = Entity(
          map['id'],
          map['titulo'],
          map['subtitulo'],
        );
        entities.add(entity);
      }
      return entities;
    });
  });
}

The stacktrace shown:

E/SQLiteLog(21931): (1) no such table: entidade in "SELECT * FROM entity"

Delete the app from the emulator or the physical device and re-install it for the db to be initialized and all the neccesasry tables will be created.
