I have tried to establish blynk code using UIFlow block.
However, there is an error "nonetype object isn't callable"
on the line "@blynk.handle_event('write v*')'.

How can I solve this?

from m5stack import *
from m5ui import *
from uiflow import *
from ble import blynk

setScreenColor(0x222222)




label0 = M5TextBox(13, 40, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
label1 = M5TextBox(13, 69, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
title0 = M5Title(title="Title", x=3 , fgcolor=0xFFFFFF, bgcolor=0x0000FF)

num0 = None
message = None



@blynk.handle_event('write v*')
def blynk_write(*args):
  # global num0, message
  num0, message = args[0], args[1]
  if num0 == 15:
    label0.setText(str(message[0]))
    label1.setText(str(message[1]))

  pass



blynk.init('RoboCar', '---', blynk.BLE)
label0.setText(str(power.getBatteryLevel()))
