How can I set two container on top of each other? - flutter

Question

im trying to set 2 containers on top of each other. What I want is to showing a star and when user pressed the star I wanna open 5 star so he can vote . Im not really sure if im thinking the correct way . But fr that I wanna create one container and in another container directly above this stars container displaying all other buttons how's just buttons to clock normally . I hope that you understand what I trying to do. So when im putting the star container also in the same container they buttons when opening all stars the whole container will move isn't?
So heres im trying to do.
class VideoPage extends StatelessWidget {
static const route = '/Video';
#override
Widget build(BuildContext context) {
return Scaffold(
body: Column(
children: [
Container(
height: 100,
color: Colors.yellow[300],
),
Expanded(
child: Row(
children: [
Expanded(
child: Container(color: Colors.green[300]),
),
Container(
width: 100,
color: Colors.orange[300],
),
Container(
width: 100,
color: Colors.red[300],
),
],
),
),
Container(
height: 80,
color: Colors.blue[300],
),
],
),
);
}
}
This look like that:
And I want that the orange one is directly under the red one so there will be first one star and on pressing it open 5 stars . Is this possible what im trying ? If so please help . If not please help haha

Answer 1

What you need to use is the Stack Widget:
Stack(
children: <Widget>[
BottomWidget(),
MiddleWidget(),
TopWidget(),
],
),
The last widget of the children is the top layer, structure descending.

EDIT:
In your case if you want the orange one underneath, you have to do some changes within your structure and split it from your Row()
Example
import 'package:flutter/material.dart';
final Color darkBlue = Color.fromARGB(255, 18, 32, 47);
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData.dark().copyWith(scaffoldBackgroundColor: darkBlue),
debugShowCheckedModeBanner: false,
home: Scaffold(
body: Center(
child: MyWidget(),
),
),
);
}
}
class MyWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Column(
children: [
Container(
height: 100,
color: Colors.yellow[300],
),
Stack(
children: <Widget>[
Container(
width: MediaQuery.of(context).size.width *1,
height: 200,
color: Colors.orange,
),
Container(
height:200,
child: Row(
children: [
Expanded(
child: Container(color: Colors.green[300]),
),
Container(
width: 100,
color: Colors.red.withOpacity(0.5),
),
],
)),
],
),
Container(
height: 80,
color: Colors.blue[300],
),
],
),
);
}
}
