Container is flickering or bouncing when notification value changed in ValueListenalbeBuilder

I have calendar text come from javascript using flutter_js. I used this calendar text widget in header widget as follow in home screen. Every time, navigate to home screen, screen is flickering or bouncing. If I take out this calendar widget, screen rendering is smooth.

If I put container height as follow, it is working as expected but I can't put the height because of the different size of screen.

Container(
            height: 100,
            padding:
                const EdgeInsets.only(top: 10, left: 20, right: 20, bottom: 10),
            child: const MyanmarCalender(),
          ),
