• General

There are a couple of ways to add a border to a Flutter widget. The most basic way is to wrap your widget in a DecoratedBox. However, the Container widget also has a DecoratedBox built-in. So in this article, we are going to see How to Add Bottom Elevation to a Container In Flutter?

In this blog post, we’ll guide you through the process of adding bottom elevation to a Container in Flutter. If you want to enhance the visual appeal and depth of your UI, this comprehensive guide is here to help you understand the techniques and steps involved. We’ll explore different approaches to achieving a bottom elevation effect, including using the Material widget, applying BoxShadow, and customizing the Container’s decoration properties. You’ll learn how to control the elevation level, adjust the shadow color and spread, and create a visually stunning container with a realistic sense of depth.

Add Bottom Elevation to a Container In Flutter

Use ClipRRect to remove shadow effects and add a bottom margin to Container to overcome ClipRRect at the bottom only to show shadow effect.

import "package:flutter/material.dart";

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  Widget build(BuildContext context) {
    return MaterialApp(
      home: HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Padding(
          padding: const EdgeInsets.all(30.0),
          child: ClipRRect(
            borderRadius: BorderRadius.circular(5.0),
            child: Container(
              height: 100.0,
              margin: const EdgeInsets.only(bottom: 6.0), //Same as `blurRadius` i guess
              decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(5.0),
                color: Colors.white,
                boxShadow: [
                  BoxShadow(
                    color: Colors.grey,
                    offset: Offset(0.0, 1.0), //(x,y)
                    blurRadius: 6.0,
                  ),
                ],
              ),
            ),
          ),
        ),
      ),
    );
  }
}

Result:

In my option, the best way is to add Material() over the widget you are currently using.

return Material(
       elevation: 20,
       child Container(),
       );

If you only want to add a shadow then BoxDecoration combined with BoxShadow will.

Code Snippet will look like the below:

...
...
body: Container(
    margin: EdgeInsets.all(8),
    decoration: BoxDecoration(
        borderRadius: BorderRadius.circular(8.0),
        color: Colors.white,
        boxShadow: [
            BoxShadow(
                color: Colors.black,
                blurRadius: 2.0,
                spreadRadius: 0.0,
                offset: Offset(2.0, 2.0), // shadow direction: bottom right
            )
        ],
    ),
    child: Container(width: 100, height: 50) // child widget, replace with your own
),
...
...

So the above code will give us output like the below:

Use Material and must use borderRadius: same for Container() and Material()

Material(
                elevation: 5,
                borderRadius: BorderRadius.only(topLeft: Radius.circular(50)),
                child: Container(
                  height: 100,
                  width: _width / 1.1,
                  decoration: BoxDecoration(
                      color: Colors.amber,
                      borderRadius:
                          BorderRadius.only(topLeft: Radius.circular(50))),
                ),
              ),
