DatabaseProvider class abstract

数据库提供者抽象接口 / Database provider abstract interface

通过实现此接口，可以支持多种数据库类型（SQLite、Hive、Isar等） By implementing this interface, multiple database types can be supported (SQLite, Hive, Isar, etc.)

实现示例 / Implementation example:

class MyCustomDatabaseProvider implements DatabaseProvider {
  @override
  String get name => 'CustomDB';

  @override
  Future<List<DatabaseInfo>> getDatabases() async {
    // 返回数据库列表 / Return database list
    return [];
  }

  @override
  Future<QueryResult> queryTable(String dbPath, String tableName, {int limit = 50}) async {
    // 执行查询并返回结果 / Execute query and return result
    return QueryResult(columns: [], rows: []);
  }
}
