Getting width is easy but height can be tricky, following are the ways to deal
with height

// Full screen width and height
double width = MediaQuery.of(context).size.width;
double height = MediaQuery.of(context).size.height;

// Height (without SafeArea)
var padding = MediaQuery.of(context).padding;
double height1 = height - padding.top - padding.bottom;

// Height (without status bar)
double height2 = height - padding.top;

// Height (without status and toolbar)
double height3 = height - padding.top - kToolbarHeight;
