Can I programmatically change the color of a TextField background?

Question

I am facing a similar issue here. Instead of this I would like to change the text color if the input is not numerical. I am doing so using a separated method that changes the value of a class variable but after changing the variable there is no change in the color of the text even using self.update()

Code sample

`
def build(self):

    
self.colorTab = colors.BLUE

#This bit is in a container with several ElevatedButtons and TextFields
        Row(controls=[ElevatedButton(text='Left',
 
        on_click=self.event_move, 
        data=[self.distanceXY, 'Left']),         
        flet.TextField(label='XY',
  
        value=str(self.distanceXY),
 
        expand=False,
  
        width=60,
        text_align=TextAlign.CENTER,
 
        on_change=self.distanceXY_change,
 
        bgcolor=self.colorTab
 )

        def distanceXY_change(self, e):
   
                if not '.'in e.control.value and e.control.value != '':
       
                        try:
            
                                float(e.control.value)
 
                         except Exception:
            
                                print('Value not valid')
            
                          self.distanceXY=0
            
                                self.colorTab=colors.RED
        
                         else:
           
                         self.distanceXY= e.control.value
    
                else:
        print('Value not valid')
`
