How can I stop the background screen is moving to another screen while alert box appears?

Question

I'm using 4 images in each screen. By setting the timer I can see the screen changing within 4 seconds automatically. In each screen below I have given a button for alter dialog box. When I click on button it will show the alert dialog box, the background images screen is moving to another screen. I want to stop background screen when dialog box appears.

Is there any way to achieve this?

Thanks in advance.

You need to cancel your timer when alert appears. If you cant reference to it inside here:

 onHomeButtonClick: () {
   _showcontent();// method for altert dailog box                                                                                     
                        },

You can pass a variable like var shouldContinue = True somewhere before and switch it to false when button is clicked
