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   lt Widget gt                   MORE OF YOUR CODE

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 only        topLeft  Radius circular 10           topRight  Radius circular 10           bottomLeft  Radius circular 10           bottomRight  Radius circular 10             boxShadow          BoxShadow          color  Colors grey withOpacity 0 5           spreadRadius  5          blurRadius  7          offset  Offset 0  3      changes position of shadow                         Screenshot

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   lt Widget gt                 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

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     gt  runApp MyApp      class MyApp extends StatelessWidget      override   Widget build BuildContext context        return MaterialApp        home  Scaffold          body  ShadowDemo                           class ShadowDemo extends StatefulWidget      override    ShadowDemoState createState     gt   ShadowDemoState       class  ShadowDemoState extends State lt ShadowDemo gt      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   lt Widget gt           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                                    Align            alignment  Alignment bottomCenter            child  Padding              padding  const EdgeInsets only bottom  80 0               child  Column                children   lt Widget gt                   Spacer                    Slider                    value   opacity                    min  0 0                    max  1 0                    onChanged   newValue    gt                                          setState      gt   opacity   newValue                                                          Slider                    value   xOffset                    min  -100                    max  100                    onChanged   newValue    gt                                          setState      gt   xOffset   newValue                                                          Slider                    value   yOffset                    min  -100                    max  100                    onChanged   newValue    gt                                          setState      gt   yOffset   newValue                                                          Slider                    value   blurRadius                    min  0                    max  100                    onChanged   newValue    gt                                          setState      gt   blurRadius   newValue                                                          Slider                    value   spreadRadius                    min  0                    max  100                    onChanged   newValue    gt                                          setState      gt   spreadRadius   newValue
