I have tried to adjust height of the main container (that contains all elements) by pixel or percentage and there is no way to ensure the content fits exactly the screen size of all devices. on some devices the content overshoots the navbar, on some it doesnt fill up so theres extra space at the bottom. I have both appbar and navbar. i think its due to the navbar being set to fixed pixels... i dont get why appbar we can adjust the height but for navbar we cant. Like I had to keep adjusting the height of the main container to figure out wheat height it should be to fit the content exactly in the remaining screen space excluding appbar and navbar. like couldnt yall provide the height for the navbar? so we can calculate how much height is left for the content? or better, let us adjust the height of the navbar.
