VkWave

from vkwave.bots import SimpleLongPollBot
import logging
from state_manager.routes.vkwave.state import VkWaveMainStateRouter
from state_manager.models.state_managers.vkwave import VkWaveStateManager

logging.basicConfig(level=logging.INFO)

bot = SimpleLongPollBot(tokens="your token", group_id=123123,)
main_state = VkWaveMainStateRouter(bot)

@main_state.message_handler()
async def home(event: bot.SimpleBotEvent, state_manager: VkWaveStateManager):
    await event.answer("go to home2")
    await state_manager.set_next_state("home2")

@main_state.message_handler()
async def home2(event: bot.SimpleBotEvent, state_manager: VkWaveStateManager):
    await event.answer("go to home")
    await state_manager.back_to_pre_state()

main_state.install()
bot.run_forever(ignore_errors=True)

Aiogram

import logging
from aiogram import Bot, Dispatcher, executor, types
from state_manager.models.state_managers.aiogram import AiogramStateManager
from state_manager.routes.aiogram.state import AiogramMainStateRouter

logging.basicConfig(level=logging.INFO)

bot = Bot(token='your token')
dp = Dispatcher(bot)
main_state = AiogramMainStateRouter(dp)
main_state.install()

@main_state.message_handler()
async def home(msg: types.Message, state_manager: AiogramStateManager):
    await msg.answer("go to home2")
    await state_manager.set_next_state("home2")

@main_state.message_handler()
async def home2(msg: types.Message, state_manager: AiogramStateManager):
    await msg.answer("go to home")
