2 Min Read

To complete Mobile app UI design shadows takes someplace. In Flutter adding shadows to the widget is very easy. There are some ways we can achieve shadow in widgets. In this Tutorial, we see the two methods.

  • Using Container Widget
  • Using Card Widget

1. Using Container Widget

The Container widget is one of the popular widgets in the flutter. As you know the Container widget has the decoration property. The decoration property takes the BoxShadow.

BoxShadow Example,

boxShadow: [
                color: Colors.grey.withOpacity(0.5),
                spreadRadius: 5,
                blurRadius: 7,
                offset: const Offset(0, 3), // changes position of shadow

Full Container Widget example,

              const EdgeInsets.only(left: 30, top: 100, right: 30, bottom: 50),
          height: MediaQuery.of(context).size.height / 2,
          width: double.infinity,
          decoration: BoxDecoration(
            color: Colors.white,
            borderRadius: const BorderRadius.only(
                topLeft: Radius.circular(10),
                topRight: Radius.circular(10),
                bottomLeft: Radius.circular(10),
                bottomRight: Radius.circular(10)),
            boxShadow: [
                color: Colors.grey.withOpacity(0.5), //shadow color
                spreadRadius: 5, // spread radius
                blurRadius: 7, // shadow blur radius
                offset: const Offset(0, 3), // changes position of shadow
Flutter BoxShadow Example

You can change the shadow position by changing the offset value. Also, you can change the shadow color, blur radius, spread radius.

Next, we will see the second method.

2. Using Card Widget

          elevation: 8,
          child: Container(
            width: 300,
            height: 200,
