i have screen height 844 and bottom kBottomNavigationBarHeight 87 and before bottomNav i have a button which i want to give a margin between the button and bottomNav to look like this

i want the margin to be responsive so in every device it will look like the image above, so i have a logic to get the margin height by calculating screen height and kBottomNavigationBarHeight but i don’t know how to calculate it or is there someway to achieve this better ?

what i’ve tried

 EdgeInsets.only(top: Get.height / kBottomNavigationBarHeight)

this is for full image of the screen

>Solution :

I haven’t seen your full code but,

I assume you use Column to show all the widgets (since it overflows).
Maybe your code looks like this:

class MyScreen extends StatelessWidget {
  const MyScreen({super.key});

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        UpperPart(),
        MovieTitle(),
        MovieStats(),
        MovieDescription(),
        RatingButton(),
        BottomNav(),
      ]
    );
  }
}

If you want to show the button over the bottom nav with the same height:

class MyScreen extends StatelessWidget {
  const MyScreen({super.key});

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        UpperPart(),
        MovieTitle(),
        MovieStats(),
        MovieDescription(),
        Spacer(), // fills the remaining space
        RatingButton(),
        SizedBox(height: 30), // Adjust this value to your specification. 
        BottomNav(),
      ]
    );
  }
}

But this may not solve the overflow problem.
Maybe moving the Uppersection (UpperPart to MoviewDescription) to a scrollable widget may be the solution

class MyScreen extends StatelessWidget {
  const MyScreen({super.key});

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        Expanded(
          child: SingleChildScrollView(
            child: Column(
              children: [
                UpperPart(),
                MovieTitle(),
                MovieStats(),
                MovieDescription(),
              ]
            )
          ),
        ),
        RatingButton(),
        SizedBox(height: 30), // Adjust this value to your specification. 
        BottomNav(),
      ]
    );
  }
}

hope it helps!
