AttributeError: module 'aiogram.dispatcher' has no attribute 'message_handler'

#bot

bot = Bot(token="************")
dp = dispatcher
@dp.message_handler
async def echo(message: types.Message):
    await message.answer(message.text)

if __name__ == "__main__":
    executor.start_polling(dp, skip_updates=True)
