You can achieve this with more than one ways. But I think the simplest way is that make Row as parent widget put all the ListView in Row after wrapping every ListView by Expanded widget.
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Padding(
padding: const EdgeInsets.symmetric(horizontal: 10.0),
child: Row(
children: <Widget>[
Expanded(
child: ListView.separated(
itemCount: 10,
controller: ScrollController(),
separatorBuilder: (_, __) => const SizedBox(height: 10),
itemBuilder: ((context, index) => Container(
height: 80,
width: double.infinity,
color: Colors.red,
)),
),
),
const SizedBox(width: 10),
Expanded(
child: ListView.separated(
controller: ScrollController(),
itemCount: 2,
separatorBuilder: (_, __) => const SizedBox(height: 10),
itemBuilder: ((context, index) => Container(
height: 100,
width: double.infinity,
color: Colors.yellow,
)),
),
),
const SizedBox(width: 10),
Expanded(
child: ListView.separated(
controller: ScrollController(),
itemCount: 6,
separatorBuilder: (_, __) => const SizedBox(height: 10),
itemBuilder: ((context, index) => Container(
height: 70,
width: double.infinity,
color: Colors.green,
)),
),
)
],
),
),
);
}

Wrap with SingleChildScrollView over every page you want to scroll.
And also mention the scrollDirection: Axis.vertical.
I hope it works! :)

First must wrap it with a single scroll child view.
Then wrap it in rows,
Then wrap it in a ListView
Use expanded so everything can be seen.
I hope this works for you.

class myScroll extends MaterialScrollBehavior {
#override
Set<PointerDeviceKind> get dragDevices => {
PointerDeviceKind.touch,
PointerDeviceKind.mouse,
};
}

Try wrapping your listview into Expanded() widget which will allow to take all available space

Just add physics: ClampingScrollPhysics(), in your ListView.builder properties.
Example:
Container(
child: ListView.builder(
primary: false,
scrollDirection: Axis.vertical,
shrinkWrap: true,
physics: ClampingScrollPhysics(),
itemBuilder: (context, index) {
return cartItems(index);
},
itemCount: 3,
),
)
You can do it using SingleChildScrollView :
for horizontal scrolling
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: [],
),
),
for vertical scrolling
SingleChildScrollView(
scrollDirection: Axis.vertical,
child: Column(
children: [],
),
),
return Scaffold(
appBar: AppBar(....),
body: Container(
child: Column(children: [
Container(
height: 90,
width: MediaQuery.of(context).size.width,
child: Padding(
padding:
const EdgeInsets.only(top: 5, bottom: 5, left: 1, right: 1),
child: Container(
child: ListView.builder(
scrollDirection: Axis.horizontal,
itemBuilder: (context, index) {
return categoryItemsTabs(index);
},
itemCount: 5,
),
),
),
),
Expanded(
child: Container(
child: ListView.builder(
scrollDirection: Axis.vertical,
itemBuilder: (context, index) {
return cartItems(index);
},
itemCount: 3,
),
),
)
]),
),
);

How to change the text in first screen when there is any change in third screen using provider package in flutter?

I have a firstscreen called including stateful widget, PlantFeatureScreen1 where I have to show the change when the update occurs in thirdscreen which also includes a stateful widget, CartDetais3.
How can i update the first screen when changes happens in third screen and addQuantity and subtractQuantity functions will be added in third screen? Please suggest using provider package.
firstScreen code Here I have to show the change in very last center widget of this widget tree.
class PlantFeatureScreen1 extends StatefulWidget {

The above code is ready to be pasted into the main.dart file and preview on a the virtual device (preferably tablet).
So far I have tried the solutions I found on these posts to no avail:
- Make container widget fill parent vertically
- Flutter Container height same as parent height
- Flutter expand Container to fill remaining space of Row
- The equivalent of wrap_content and match_parent in flutter?
Since the Row that contains the section Container also has a ListView being generated with the FutureBuilder, the height of the Row automatically expands to fit the ListView. I also want the section Container to expand to the same height as the how the Row widget is expanding; i.e., The bottom border of the section Container that says FRONT, should be aligned with the bottom border of the Hight Voltage system and the right border of the FRONT section Container, should go all the way to the top.
I already spent 3 days without a resolution.
Edit
I have tried the suggestion on the answer provided by #MaadhavSharma but I get the following exception:
════════ Exception Caught By rendering library ════════════════════════════
The following assertion was thrown during performLayout():
BoxConstraints forces an infinite height.

Basically I changed the ListView of the second element of the Row for a Column, since it already was inside a ListView and that was making it have double scroll and the heights weren't expanding the height of the row properly, and also I wrapped the Row inside an IntrinsicHeight and put crossAxisAlignment: CrossAxisAlignment.stretch to the Row so the content will fit the height of the Row.
The use of IntrinsicHeight is expensive, but I don't see another solution for the way you structured the widgets. I recommend you to try to optimize all the structure so you could find a better and optimal solution.
If you want to stretch the Container to match its parent, use double.infinity for the height and width properties
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Container as a layout')),
body: Container(
height: double.infinity,
width: double.infinity,
color: Colors.yellowAccent,
child: Text("Hi"),
),
);
}
The trick is to use constraints: BoxConstraints.expand() in some of your containers that you want to expand to fill the row height.
Try something like this:
Scaffold(
appBar: AppBar(
title: Text("Title"),
),
body: Container(
padding: EdgeInsets.all(16.0),
child: Column(
children: <Widget>[
Expanded(
flex: 2,
child: Container(
padding: EdgeInsets.fromLTRB(0, 0, 0, 0),
color: Colors.yellow,
child: Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
constraints: BoxConstraints.expand(),
color: Colors.blue,
child: Text("box 1")),
),
Expanded(
flex: 2,
child: Container(
constraints: BoxConstraints.expand(),
color: Colors.red,
child: Column(
children: <Widget>[
Expanded(
flex: 2,
child: Container(
padding:
EdgeInsets.fromLTRB(0, 0, 0, 0),
color: Colors.yellow,
child: Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
constraints:
BoxConstraints.expand(),
color: Colors.lightGreen,
child: Text("box 2")),
),
Expanded(
flex: 2,
child: Container(
constraints:
BoxConstraints.expand(),
color: Colors.lightBlue,
child: Text("box 3")),
),
],
),
),
),
Expanded(
flex: 1,
child: Container(
padding:
EdgeInsets.fromLTRB(0, 0, 0, 0),
color: Colors.yellow,
child: Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
constraints:
BoxConstraints.expand(),
color: Colors.purple,
child: Text("box 4")),
),
Expanded(
flex: 2,
child: Container(
constraints:
BoxConstraints.expand(),
color: Colors.orange,
child: Text("")),
),
],
),
),
),
],
)),
),
],
),
),
),
Expanded(
flex: 1,
child: Container(
padding: EdgeInsets.fromLTRB(0, 0, 0, 0),
color: Colors.yellow,
child: Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(

I think you will need to use some fixed heights since you are using ListView and FutureBuiulders. If you can get rid of FutureBuilders, you can probably achieve dynamic heights. Notice the hright of 320 on the parent row and height of 160 on child rows.
But have a look at this:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Assemblers Tasks',
debugShowCheckedModeBanner: false,
theme: ThemeData(
primarySwatch: Colors.deepOrange,
),
home: MyHomePage(title: 'Assembly Tasks'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
String dropdownValue;
List<Map<String, dynamic>> buildItems = [];
getBuilds() {
List<Map<String, dynamic>> items = [];
items.add({"id": 10, "vehicleModel": "A10", "vehicleNumber": "TEST-00010"});
setState(() {
buildItems = items;
});
}
List<Map<String, dynamic>> buildSections = [];
getSections() {
List<Map<String, dynamic>> items = [];
items.add({
"id": 5,
"section": "Front",
});
items.add({
"id": 15,
"section": "Rear",
});
setState(() {
buildSections = items;
});
}
Future<List<Map<String, dynamic>>> getSystems(String buildSectionId) async {
List<Map<String, dynamic>> items = [];
if (int.parse(buildSectionId) == 5) {
items.add({
"id": 4,
"system": "Hydraulics",
});
items.add({
"id": 20,
"system": "High Voltage",
});
}
return items;
}

getBuilds();
super.initState();
