How can I add shadow to the widget in flutter?

Question

How can I add shadow to the widget like in the picture below?

This is my current widget code.

Image with shadow

Wrap your widget with Material() widget and give elevation: 10.0 — Jerin

Check out BoxShadow and BoxDecoration

A Container can take a BoxDecoration (going off of the code you had originally posted) which takes a boxShadow

return Container(
  margin: EdgeInsets.only(left: 30, top: 100, right: 30, bottom: 50),
  height: double.infinity,
  width: double.infinity,
  decoration: BoxDecoration(
    color: Colors.white,
    borderRadius: BorderRadius.all(Radius.circular(10)),
    boxShadow: [
      BoxShadow(
        color: Colors.grey.withValues(alpha: 0.5),
        spreadRadius: 5,
        blurRadius: 7,
        offset: Offset(0, 3), // changes position of shadow
      ),
    ],
  ),
)

Great answer - tnx! How would you have the ripple effect over the button? currently it's rippling under the button.

Vinoth Over a year ago

It's better to use borderRadius: BorderRadius.circular(10.0) if every border is same.

Slick Slime Over a year ago

@nitzanwe you can wrap a widget in InkWell widget to get ripple effect on tapping.

The link you mentioned is not working. Changing the domain from flutter.io to flutter.dev works

Screenshot:

Using `BoxShadow` (more customizations):

Container(
  width: 100,
  height: 100,
  decoration: BoxDecoration(
    color: Colors.teal,
    borderRadius: BorderRadius.circular(20),
    boxShadow: [
      BoxShadow(
        color: Colors.red,
        blurRadius: 4,
        offset: Offset(4, 8), // Shadow position
      ),
    ],
  ),
)

Using `PhysicalModel`:

PhysicalModel(
  color: Colors.teal,
  elevation: 8,
  shadowColor: Colors.red,
  borderRadius: BorderRadius.circular(20),
  child: SizedBox.square(dimension: 100),
)

Using `Card`:

Card(
  elevation: 8,
  shadowColor: Colors.red,
  child: Container(
    width: 100,
    height: 100,
    color: Colors.teal,
  ),
)

Using `Material`:

Material(
  elevation: 8,
  color: Colors.teal,
  shadowColor: Colors.red,
  borderRadius: BorderRadius.circular(20),
  child: SizedBox.square(dimension: 100),
)

Use BoxDecoration with BoxShadow.

Here is a visual demo manipulating the following options:

opacity
x offset
y offset
blur radius
spread radius

The animated gif doesn't do so well with colors. You can try it yourself on a device.

Here is the full code for that demo:

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: ShadowDemo(),
      ),
    );
  }
}

class ShadowDemo extends StatefulWidget {
  @override
  _ShadowDemoState createState() => _ShadowDemoState();
}

class _ShadowDemoState extends State<ShadowDemo> {
  var _image = NetworkImage('https://placebear.com/300/300');

  var _opacity = 1.0;
  var _xOffset = 0.0;
  var _yOffset = 0.0;
  var _blurRadius = 0.0;
  var _spreadRadius = 0.0;

  @override
  Widget build(BuildContext context) {
    return Stack(
      children: <Widget>[
        Center(
          child:
          Container(
            decoration: BoxDecoration(
              color: Color(0xFF0099EE),
              boxShadow: [
                BoxShadow(
                  color: Color.fromRGBO(0, 0, 0, _opacity),
                  offset: Offset(_xOffset, _yOffset),
                  blurRadius: _blurRadius,
                  spreadRadius: _spreadRadius,
                )
              ],
            ),
            child: Image(image:_image, width: 100, height: 100,),

PhysicalModel will help you to give it elevation shadow.

 Container(
        alignment: Alignment.center,
        child: Column(
          children: <Widget>[
            SizedBox(
              height: 60,
            ),
            Container(
              child: PhysicalModel(
                borderRadius: BorderRadius.circular(20),
                color: Colors.blue,
                elevation: 18,
                shadowColor: Colors.red,
                child: Container(
                  height: 100,
                  width: 100,
                ),
              ),
            ),
            SizedBox(
              height: 60,
            ),
            Container(
              child: PhysicalShape(
                color: Colors.blue,
                shadowColor: Colors.red,
                elevation: 18,
                clipper: ShapeBorderClipper(shape: CircleBorder()),
                child: Container(
                  height: 150,
                  width: 150,
                ),
              ),
            )

Use Material with shadowColor inside Container like this:

Container(
  decoration: BoxDecoration(
      borderRadius: BorderRadius.only(
          bottomLeft: Radius.circular(10),
          bottomRight: Radius.circular(10)),
      boxShadow: [
        BoxShadow(
            color: Color(0xffA22447).withOpacity(.05),
            offset: Offset(0, 0),
            blurRadius: 20,
            spreadRadius: 3)
      ]),
  child: Material(
    borderRadius: BorderRadius.only(
        bottomLeft: Radius.circular(10),
        bottomRight: Radius.circular(10)),
    elevation: 5,
    shadowColor: Color(0xffA22447).withOpacity(.05),
    color: Color(0xFFF7F7F7),
    child: SizedBox(
      height: MediaQuery.of(context).size.height / 3,
    ),
  ),
)

        spreadRadius: 2.0, // has the effect of extending the shadow
        offset: Offset(

The given answers do the trick for outer shadow i.e. around the widget. I wanted a shadow on the widget which is inside the boundaries and according to the github issue there is no inset attribute in ShadowBox yet. My workaround was to add a layer of widget with a gradient using the stack widget so that it looks like the widget itself has the shadows. You must use the mediaQuery for dimensions otherwise the layout will be messed up on different devices. Here's a sample of code for better understanding:

Stack(
            children: <Widget>[
              Container(
                decoration: BoxDecoration(
                  image: DecorationImage(
                    fit: BoxFit.cover,
                    image: AssetImage("assets/sampleFaces/makeup.jpeg"),
                    // fit: BoxFit.cover,
                  ),
                ),
                height: 350.0,
              ),
              Container(
                decoration: BoxDecoration(
                  gradient: LinearGradient(
                    begin: FractionalOffset.topCenter,
                    end: FractionalOffset.bottomCenter,
                    colors: [
                      Colors.black.withOpacity(0.0),
                      Colors.black54,
                    ],
                    stops: [0.95, 5.0],
                  ),
                ),
              )

Maybe it is sufficient if you wrap a Card around the Widget and play a bit with the elevation prop.

I use this trick to make my ListTile look nicer in Lists.

For your code it could look like this:

return Card(
   elevation: 3, // PLAY WITH THIS VALUE 
   child: Row(
      crossAxisAlignment: CrossAxisAlignment.center,
      children: <Widget>[
         // ... MORE OF YOUR CODE 
      ],
   ),
);

Before you start reinventing the wheel with one of these answers, check out the Material Card widget. It also allows you to define a global style via the app theme directly:

To add shadow to an any widget in flutter, You can just wrap that widget with Container and set following properties:

Container(
  decoration: BoxDecoration(
    boxShadow: [
      BoxShadow(
        color: Colors.grey.withOpacity(0.5),
        spreadRadius: 2,
        blurRadius: 5,
        offset: Offset(0, 3),
      ),
    ],
  ),
  child: YourWidget(), // Replace YourWidget with your desired widget
);

This causes the entire container to be covered with 50% gray, it's not the right solution.

You can manage shadow with given properties. @LukeHutchison Thanks though

If you are using the Material Design spec inside Flutter, you can use a helper kElevationToShadow to create shadows that match the elevation property used in other Material components.

You can see the documentation for this property here: https://api.flutter.dev/flutter/material/kElevationToShadow-constant.html

The following elevations have defined shadows: 1, 2, 3, 4, 6, 8, 9, 12, 16, 24

Example with a Container:

Container(
  decoration: BoxDecoration(
    color: Colors.white,
    boxShadow: kElevationToShadow[8],
  ),
)

This is an easy way to add shadows that match the Material specifications, the bigger the elevation the deeper the shadow, so you can play with this value until it fits your purpose.

BoxDecoration only works on rectangular shapes. If you want to add a shadow to any arbitrary shape (including a PNG image with transparent regions), you can combine a few of Flutter's built in shaders to produce the effect:

ColorFilter to desaturate the colors add an new tint.
ImageFilter.blur to blur the shadow.

Then the original can be stacked on top with a Stack and an Offset.

These steps are included in my shadow_widget package. You can use the package directly or copy the source code to your project.

ShadowWidget(
  offset: Offset(10, 10),
  color: Colors.black.withOpacity(0.5),
  blurRadius: 10.0,
  child: MyWidget(),
),

This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, provide answers that don't require clarification from the asker. - From Review
