ListView.builder inside futurebuilder inside Listview - flutter

Question

I wanted to to make my home page scrollable i mean i want to scroll everthing on the body so i made a list view and inside the list view there are other widgets and under those widgets i want to show a future builder that has another listview.builder in it but i dont want it to be scrolled alone i want it to be scrolled with the other widgets in the home screen
this is my home screen body:
body: SafeArea(
child: ListView(
children: <Widget>[
Search(),
FeaturedProducts(),
OnSaleProducts(),
],
),
),
OnSaleProducts() is the widget that has a futurebuilder in it this is the code
Widget build(BuildContext context) {
return Container(
height: MediaQuery.of(context).size.height,
child: FutureBuilder(
future: getOnSaleProduct(),
builder: (_, snapshot){
if (snapshot.connectionState == ConnectionState.waiting) {
return ListView.builder(
itemCount: 4,
itemBuilder: (_, index) {
return Column(
);
});
}else return ListView.builder(
scrollDirection: Axis.vertical,
itemCount: 9,
itemBuilder: (_, index) {
return InkWell(child: ProductCard(name: "new", price: 123, picture: '', onSale: true));
});
}));
}

Answer 1

Then you should not use a ListView inside OnSalesProduct() but a simple Column!
Column(children: List.generate(count, (int index) => widget(index))

Answer 2

Hopefully, what you are trying to know:
Scroll everthing on the body
Inside the scrollable view, want to show a future builder that has
another listview.builder
Don't want it to be scrolled alone it to be scrolled with the other
widgets in the home screen
Let's try this code, hopefully you will get your answerers and solution together:
SingleChildScrollView(
child: Column(
children: <Widget>[
Search(),
FeaturedProducts(),
OnSaleProducts(),
],
),
),
Now do this for OnSaleProducts() widget:
Widget build(BuildContext context) {
return Container(
height: MediaQuery.of(context).size.height, // better for fixed size
width: double.infinity,
child: FutureBuilder<PopularFoodList>(
future: getOnSaleProduct(),
builder: (BuildContext context, snapshot) {
if (snapshot.hasData) {
return ListView.builder(
scrollDirection: Axis.vertical,
itemCount: 9,
itemBuilder: (context, index) {
var item = snapshot.data[index]; // snapshot.data.anotherProperty[index]; // If your model has anotherProperty
return InkWell(child: ProductCard(name: item.name, price: item.price, picture: '', onSale: true));
});
} else if (snapshot.hasError) {
return Center(child: Text(snapshot.error.toString()));
}
return Center(child: CircularProgressIndicator());
})
);
}
