Though i am late with the solution, but this may help others searching for it. The following code snippets details how it can be achieved.
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
Color myColor = Color(0xff00bfa5);
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: "Rounde Alert Box",
home: Scaffold(
appBar: AppBar(
backgroundColor: myColor,
title: Text("Rounded Alert Box"),
),
body: RoundedAlertBox(),
),
);
}
}
class RoundedAlertBox extends StatefulWidget {
@override
_RoundedAlertBoxState createState() => _RoundedAlertBoxState();
}
class _RoundedAlertBoxState extends State<RoundedAlertBox> {
@override
Widget build(BuildContext context) {
return Center(
child: RaisedButton(
onPressed: openAlertBox,
color: myColor,
child: Text(
"Open Alert Box",
style: TextStyle(color: Colors.white),
),
),
);
}
openAlertBox() {
return showDialog(
context: context,
builder: (BuildContext context) {
return AlertDialog(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(32.0))),
contentPadding: EdgeInsets.only(top: 10.0),
content: Container(
width: 300.0,
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text(
"Rate",
style: TextStyle(fontSize: 24.0),
),
Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Icon(
Icons.star_border,
color: myColor,
size: 30.0,
),
Icon(
Icons.star_border,
color: myColor,
size: 30.0,
),
Icon(
Icons.star_border,
color: myColor,
size: 30.0,
),
Icon(
Icons.star_border,
color: myColor,
size: 30.0,
),
Icon(
Icons.star_border,
color: myColor,
size: 30.0,
),
],
),
],
),
SizedBox(
height: 5.0,
),
Divider(
color: Colors.grey,
height: 4.0,
),
Padding(
padding: EdgeInsets.only(left: 30.0, right: 30.0),
child: TextField(
decoration: InputDecoration(
hintText: "Add Review",
border: InputBorder.none,
),
maxLines: 8,
),
),
InkWell(
child: Container(
padding: EdgeInsets.only(top: 20.0, bottom: 20.0),
decoration: BoxDecoration(
color: myColor,
borderRadius: BorderRadius.only(
bottomLeft: Radius.circular(32.0),
bottomRight: Radius.circular(32.0)),
),
child: Text(
"Rate Product",
style: TextStyle(color: Colors.white),
textAlign: TextAlign.center,
),
),
),
],
),
),
);
});
}
}
The output of the code snippet looks like this:

The container where you set the BoxDecoration is in the widget tree under the alert dialog. Which means you are setting just a box within the padding of your Dialog. You need to create a custom AlertDialog/showDialog and set the radius there. In the custom widget you also add the button and everything where you need to work beyond that padding.
When you include the customShowDialog.dart file in your project ( gist.github.com ) where you can edit the radius here borderRadius: BorderRadius.all(Radius.circular(20.0)) and call it like this:
return new CustomAlertDialog(
content: new Container(
width: 260.0,
height: 230.0,
decoration: new BoxDecoration(
shape: BoxShape.rectangle,
color: const Color(0xFFFFFF),
borderRadius:
new BorderRadius.all(new Radius.circular(32.0)),
),
child: new Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
// dialog top
new Expanded(
child: new Row(
children: <Widget>[
new Container(
// padding: new EdgeInsets.all(10.0),
decoration: new BoxDecoration(
color: Colors.white,
),
child: new Text(
'Rate',
style: TextStyle(
color: Colors.black,
fontSize: 18.0,
fontFamily: 'helvetica_neue_light',
),
textAlign: TextAlign.center,
),
),
],
),
),
// dialog centre
new Expanded(
child: new Container(
child: new TextField(
decoration: new InputDecoration(
border: InputBorder.none,
filled: false,
contentPadding: new EdgeInsets.only(
left: 10.0,
top: 10.0,
bottom: 10.0,
right: 10.0),
hintText: ' add review',
hintStyle: new TextStyle(
color: Colors.grey.shade500,
fontSize: 12.0,
fontFamily: 'helvetica_neue_light',
),
),
)),
flex: 2,
),
// dialog bottom
new Expanded(
child: new Container(
padding: new EdgeInsets.all(16.0),
decoration: new BoxDecoration(
color: const Color(0xFF33b17c),
),
child: new Text(
'Rate product',
style: TextStyle(
color: Colors.white,
fontSize: 18.0,
fontFamily: 'helvetica_neue_light',
),
textAlign: TextAlign.center,
),
),
),
],
),
),
);
});
You will get something like this:
EDIT:
Although Flutter lately introduced theshape property which would help you with the rounded corners by setting aShapeBorder with eg
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(20.0))
),
you would still need to quickly add a custom widget for some customizations, like custom padding, as stated above.

This worked for me:
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(32.0))),

Try this code :
AlertDialog(
shape: RoundedRectangleBorder(borderRadius:
BorderRadius.all(Radius.circular(15))),
title: Text('Your title!'),
content: Container(),
);

add
showDialog(

builder: (BuildContext context) {
return AlertDialog(
shape: RoundedRectangleBorder(borderRadius: BorderRadius.all(Radius.circular(10.0))),
title: Text("Loading..."),
content: CircularProgressIndicator(),
);
},
);

You can simply use shape property of AlertDialog
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(16)))
solution9

shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(20)),
这行代码将制作带有圆角的警报对话框。

I was looking at these answers and none of them helped me achieve the desired look.
I noticed that there was a default padding so all I did was:
AlertDialog(
titlePadding: EdgeInsets.all(0),
title: Container(
height: 30.00,
width: 300.00,
decoration: BoxDecoration(
color: Colors.redAccent,
borderRadius: BorderRadius.only(topLeft: Radius.circular(32), topRight: Radius.circular(32)),
),
),
)
I overrode the titlePadding attribute and it came just right. There is also a contentPadding attribute if you find any trouble with that. I copied this from one of my apps just to show the attribute, but it is applicable to this case as well.

If you want to use the standard Dialog you can just apply a Decoration to the Container that matches your Dialog settings
showDialog(
context: context,
child: Dialog(
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(10)),
child: Column(
children: <Widget>[
Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.only(topLeft: Radius.circular(10), topRight: Radius.circular(10)),
),
child: Text('foobar'),
)
],
),
),
);

To change the appearance of the shape of the dialog, you can set the shape property of the AlertDialog to the desired shape.
AlertDialog default shape is a RoundedRectangleBorder with a radius of 4.0
AlertDialog(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(32.0),
),
)

You can use like this
using get: ------------->
Get.generalDialog(
pageBuilder: (BuildContext buildContext, Animation animation,
Animation secondaryAnimation) =>
AlertDialog(
contentPadding: EdgeInsets.zero,
// this padding user for outside of alert padding
insetPadding: EdgeInsets.symmetric(horizontal: 10),
content: Container(
height: Get.height - 300, // Change as per your requirement
width: Get.width, // Change as per your requirement
child: <Your Widget>
),
),
));
using alert dialog:------>
CustomAlertDialog(
content: new Container(
width: 260.0,
height: 230.0,
decoration: new BoxDecoration(
shape: BoxShape.rectangle,
color: const Color(0xFFFFFF),
