I'm a beginner in Flutter.
I designed this page:
Instead of repeating the entire Listview.builder. I would like to use two instances of custom Listview.builder with two lists, one list for fruits, and the other for vegetables.
As appeared in the above screen, I tried to display vegetables in the vegetables section through the following:
Listview.builder Widget:
import 'package:flutter/material.dart';
import 'package:grocery_store/models/products_list.dart';
import '../utilities/add_product.dart';
import '../utilities/constants.dart';
class ProductsListView extends StatelessWidget {
final String? productImage;
final String? productName;
final String? productCategory;
final String? productPrice;
const ProductsListView({
Key? key,
this.productImage,
this.productName,
this.productCategory,
this.productPrice,
}) : super(key: key);
#override
Widget build(BuildContext context) {
return ListView.builder(
scrollDirection: Axis.horizontal,
itemCount: fruitsList.length,
itemBuilder: (BuildContext context, int index) {
return ClipRect(
child: Container(
width: 140.0,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15.0),
color: Colors.white,
boxShadow: const [
BoxShadow(
blurRadius: 10,
color: Colors.black,
),
],
),
margin: const EdgeInsets.all(10.0),
child: Padding(
padding: const EdgeInsets.fromLTRB(20, 10, 10, 10),
child: Column(
children: [
Image.asset(
fruitsList[index].fruitImage!,
height: 80.0,
width: 90.0,
),
const SizedBox(
height: 15,
),
Row(
children: [
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
fruitsList[index].fruitName!,
style: const TextStyle(
fontSize: 15.0,
fontWeight: FontWeight.bold,
),
),
Text(
fruitsList[index].fruitCategory!,
textAlign: TextAlign.left,
style: const TextStyle(
height: 1.5,
color: kDarkGrey,
fontSize: 12.5,
fontWeight: FontWeight.bold,
),
),
],
),
],
),
Row(
children: [
Text(
fruitsList[index].fruitPrice!,
style: const TextStyle(
fontWeight: FontWeight.bold,
),
),
const Spacer(),
const AddProduct(),
],
)
],
),
),
),
);
},
);
}
}
Fruits and vegetables lists:
import '../utilities/constants.dart';
class Fruits {
final String? fruitImage;
final String? fruitName;
final String? fruitCategory;
final String? fruitPrice;
Fruits(
{this.fruitImage, this.fruitName, this.fruitCategory, this.fruitPrice});
}
final Fruits bananas = Fruits(
fruitImage: '${kFruitsImagesAsset}bananas.png',
fruitName: 'Bananas',
fruitCategory: 'Organic',
fruitPrice: '\$4.99',
);
final Fruits apples = Fruits(
fruitImage: '${kFruitsImagesAsset}apples.png',
fruitName: 'Apples',
fruitCategory: 'Organic',
fruitPrice: '\$5.00',
);
final Fruits chikku = Fruits(
fruitImage: '${kFruitsImagesAsset}chikku.png',
fruitName: 'Chikku',
fruitCategory: 'Organic',
fruitPrice: '\$9.00',
);
final Fruits peaches = Fruits(
fruitImage: '${kFruitsImagesAsset}peaches.png',
fruitName: 'Peaches',
fruitCategory: 'Organic',
fruitPrice: '\$12.00',
);
List<Fruits> fruitsList = [bananas, apples, chikku, peaches];
class Vegetables {
final String? vegetableImage;
final String? vegetableName;
final String? vegetableCategory;
final String? vegetablePrice;
Vegetables(
{this.vegetableImage,
this.vegetableName,
this.vegetableCategory,
this.vegetablePrice});
}
final Vegetables okra = Vegetables(
vegetableImage: '${kVegetablesImagesAsset}okra.png',
vegetableName: 'Okra',
vegetableCategory: 'Organic',
vegetablePrice: '\$6.99',
);
final Vegetables peas = Vegetables(
vegetableImage: '${kVegetablesImagesAsset}peas.png',
vegetableName: 'Peas',
vegetableCategory: 'Organic',
vegetablePrice: '\$10.50',
);
final Vegetables potatoes = Vegetables(
vegetableImage: '${kVegetablesImagesAsset}potatoes.png',
vegetableName: 'Potatoes',
vegetableCategory: 'Organic',
vegetablePrice: '\$5.99',
);
final Vegetables taro = Vegetables(
vegetableImage: '${kVegetablesImagesAsset}taro.png',
vegetableName: 'Taro',
vegetableCategory: 'Organic',
vegetablePrice: '\$5.50',
);
List<Vegetables> vegetablesList = [okra, peas, potatoes, taro];

Hope someone can help
You can set an other variable in constructor and call it list and pass your Vegetables and Fruits to it like this:
class ProductsListView extends StatelessWidget {
final List list;
const ProductsListView({
Key? key,
required this.list,
}) : super(key: key);
#override
Widget build(BuildContext context) {
return ListView.builder(
scrollDirection: Axis.horizontal,
itemCount: list.length,
itemBuilder: (BuildContext context, int index) {
return ClipRect(
child: Container(
width: 140.0,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15.0),
color: Colors.white,
boxShadow: const [
BoxShadow(
blurRadius: 10,
color: Colors.black,
),
],
),
margin: const EdgeInsets.all(10.0),
child: Padding(
padding: const EdgeInsets.fromLTRB(20, 10, 10, 10),
child: Column(
children: [
Image.asset(
list is List<Fruits> ? (list[index] as Fruits).fruitImage! : (list[index] as Vegetables).vegetableImage!,
height: 80.0,
width: 90.0,
),
const SizedBox(
height: 15,
),
Row(
children: [
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
list is List<Fruits> ? (list[index] as Fruits).fruitName! : (list[index] as Vegetables).vegetableName!,
style: const TextStyle(
fontSize: 15.0,
fontWeight: FontWeight.bold,
),
),
Text(
list is List<Fruits> ? (list[index] as Fruits).fruitCategory! : (list[index] as Vegetables).vegetableCategory!
textAlign: TextAlign.left,
style: const TextStyle(
height: 1.5,
color: kDarkGrey,
fontSize: 12.5,
fontWeight: FontWeight.bold,
),
),
],
),
],
),
Row(
children: [
Text(
list is List<Fruits> ? (list[index] as Fruits).fruitPrice! : (list[index] as Vegetables).vegetablePrice!,
style: const TextStyle(
fontWeight: FontWeight.bold,
),
),
const Spacer(),
const AddProduct(),
],
)
],
),
),
),
);
},
);
}
}
and use it like this:
SizedBox(
height: 215,
width: double.infinity,
child: ProductsListView(
list: vegetablesList,
),
),
SizedBox(
height: 215,
width: double.infinity,
child: ProductsListView(
list: fruitsList,
),
),
Yeah it is pretty straightfroward, just click on the listview.builder method in your project and then click on FLutter Outline on the right hand side of the Android Studio IDE window, like this :
Once you have done that the ListView.Builder will be visible in this tree of widgets. What you need to do is to right click on the widget you want to extract and then click on extract method.
you'll get a dialog asking for the name of the newly created widget :
and a new widget will be created at the bottom of your file.
Just change the parameters for both the listview.builders and it'll look something like this :
Widget build(BuildContext context) {
return CommonList(typeList: fruitslist); // use this to change the list
}
And in the newly created widget you'd need to do the same:
class CommonList extends StatelessWidget {
final List typeList; //add a list parameter
const CommonList({
Key? key, required this.typeList, //request that list parameter
}) : super(key: key);
#override
Widget build(BuildContext context) {
return ListView.builder(
scrollDirection: Axis.horizontal,
itemCount: typeList.length, // change the list type
itemBuilder: (BuildContext context, int index) {
return ClipRect(
child: Container(
width: 140.0,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15.0),
color: Colors.white,
boxShadow: const [
BoxShadow(
blurRadius: 10,
color: Colors.black,
),
],
),
margin: const EdgeInsets.all(10.0),
child: Padding(
padding: const EdgeInsets.fromLTRB(20, 10, 10, 10),
child: Column(
children: [
Image.asset(
typeList[index].fruitImage!, //update list to use it everywhere
height: 80.0,
width: 90.0,
),
const SizedBox(
height: 15,
),
Row(
children: [
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
typeList[index].fruitName!, //like here
style: const TextStyle(
fontSize: 15.0,
fontWeight: FontWeight.bold,
),
),
Text(
typeList[index].fruitCategory!, //here
textAlign: TextAlign.left,
style: const TextStyle(
height: 1.5,
color: kDarkGrey,
fontSize: 12.5,
fontWeight: FontWeight.bold,
),
),
],
),
],
),
Row(
children: [
Text(
typeList[index].fruitPrice!, //and here again
style: const TextStyle(
fontWeight: FontWeight.bold,
),
),
const Spacer(),
const AddProduct(),
],
)
],
),
),
),
);
},
);
}

I want to have a draggable bottom sheet for which I have written the code. But the problem is bottom sheet is shown properly but the body has a container and that is not shown. Can somebody help me with the same. If I run the code without bottomsheet it runs properly. I am unable to figure out where is the problem
import 'package:flutter/material.dart';
class HomePage1 extends StatelessWidget {
const HomePage1({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
double height = MediaQuery.of(context).size.height;
return Scaffold(

}),
);*/
},

}
}
DraggableScrollableSheet is always display in bottom no need to attached with bottom sheet,
Just drag into stack (as mentioned below)
Stack(

child: const Icon(

size: 15,

See the Output...
you should try a function called bottom Model sheet and make it use in your project..

I use hive to store my data locally in expense tracker app. I have saved all expenses in a box called expenseBox. I have given each expense item a date and I want items with the same date to be grouped together and displayed separately. Is there a way to achieve this?

Hey guys I'm working on some project and need to create a custom dropdown,
like this
I am able to make that here is the code, the code is messy but I will refactor it once I make it work. Or if you have some other way how I can accomplish this I'm open to suggestions.
GlobalKey? actionKey = GlobalKey();
List<String> picked = [];
List<IconData> icons = [
Icons.blur_circular_outlined,
Icons.sports_basketball,
Icons.sports_baseball_sharp,
Icons.sports_tennis_rounded,
Icons.people,
];
List<String> sports = [
"Fudbal",
"Kosarka",
"Tenis",
"Stoni tenis",
"Kuglanje"
];
List<int> ints = [0, 1, 2, 3, 4];
List<bool> booles = [false, false, false, false, false];
OverlayEntry? overlayEntry;
var position;
double? y;
double? x;
void findDropdownData() {
RenderBox renderBox =
actionKey!.currentContext!.findRenderObject() as RenderBox;
position = renderBox.localToGlobal(Offset.zero);
y = position!.dy;
x = position!.dx;
}
OverlayEntry _overlayEntryBuilder() {
return OverlayEntry(
builder: (context) {
return Positioned(
// top: position,
left: 16.w,
right: 16.w,
child: Material(
child: dropdownExpanded(),
),
);
},
);
}
Widget buildRows(i) {
return Padding(
padding: EdgeInsets.symmetric(horizontal: 17.w, vertical: 15.h),
child: Row(
children: [
SizedBox(
height: 24.h,
width: 24.w,
child: Checkbox(
activeColor: style.purpleMain,
value: booles[i],
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(4)),
onChanged: (value) {
setState(() {
booles[i] = value!;
booles[i] == true
? picked.add(sports[i])
: picked.remove(sports[i]);
});
},
),
),
SizedBox(
width: 10.w,
),
Text(
sports[i],
style: TextStyle(
color: booles[i] == true ? style.purpleMain : Colors.grey,
),
),
const Spacer(),
Icon(
icons[i],
color: booles[i] == true ? style.purpleMain : Colors.grey,
size: 15,
),
],
),
);
}
Widget dropdown() {
return GestureDetector(
key: actionKey,
onTap: () {
setState(() {
isPressed = !isPressed;
});
if (isPressed == false) {
overlayEntry = _overlayEntryBuilder();
Overlay.of(context)!.insert(overlayEntry!);
}
},
child: Container(
width: double.infinity,
height: 50.h,
decoration: BoxDecoration(
border: Border.all(color: style.e8e8e8),
borderRadius: BorderRadius.circular(8),
),
padding: EdgeInsets.only(left: 16.w, right: 13.w),
child: Row(
children: [
picked.isEmpty ? pickedEmpty() : pickedNotEmpty(),
const Spacer(),
const Icon(
Icons.arrow_drop_down,
color: style.bdbdbd,
),
],
),
),
);
}
Widget pickedEmpty() {
return Text(
"Možete obeležiti više aktivnosti",
style: TextStyle(
fontSize: 16.sp,
color: style.bdbdbd,
fontWeight: FontWeight.w400,
),
);
}
Widget pickedNotEmpty() {
List<Widget> list = <Widget>[];
for (var i = 0; i < picked.length; i++) {
list.add(
Padding(
padding: EdgeInsets.only(right: 5.w),
child: Text(
picked[i],
style: TextStyle(
fontSize: 16.sp,
color: style.bdbdbd,
fontWeight: FontWeight.w400,
),
),
),
);
}
return Row(children: list);
}
Widget dropdownExpanded() {
return Container(
decoration: BoxDecoration(
color: Colors.white,
border: Border.all(color: style.purpleMain),
borderRadius: BorderRadius.circular(8),
),
child: Column(
children: [
GestureDetector(
onTap: () {
setState(() {
isPressed = !isPressed;
});
overlayEntry?.remove();
},
child: Container(
width: double.infinity,
height: 50.h,
padding: EdgeInsets.only(left: 16.w, right: 13.w),
child: Row(
children: [
picked.isEmpty ? pickedEmpty() : pickedNotEmpty(),
const Spacer(),
const Icon(
Icons.arrow_drop_up,
color: style.bdbdbd,
),
],
),
),
),
const Divider(
height: 0,
thickness: 1,
color: style.e8e8e8,
indent: 17,
endIndent: 17,
),
Column(
children: [
for (int i in ints) buildRows(i),
],
),
],
),
);
}
Here are results
This is what I want to accomplish
So I just want to move down this expanded dropdown and how to update these booles in the overlay if I don't use overlay it's working as it should but I need to open that dropdown on the top of another content. Thanks for the help.
Use smart_select it is fully customizable and you can achieve the design you want easily using this library.
Updated Answer
Regarding the UI, it is like an Expansions Tile Widget in flutter. You can implement that dropdown with expansions tile and pass list of items in children,
for expand, collapse tile after select each item, you can create a global key and control that in UI.
final GlobalKey<AppExpansionTileState> expansionTile = new GlobalKey();
collapse → expansionTile.currentState.collapse();
ExpansionTile(
title: Text(
"Možete obeležiti više aktivnosti",
style: TextStyle(fontSize: 16.0, fontWeight: FontWeight.w500),
),
children: <Widget>[
// put items here
],
),
smaple :
Widget customDropDown() => Container(
// color: Colors.white,
padding: const EdgeInsets.all(10),
child: ListTileTheme(
dense: true,
child: ExpansionTile(
title: const Text(
"Možete obeležiti više aktivnosti",
style: TextStyle(fontSize: 16.0, fontWeight: FontWeight.w500),
),
children: <Widget>[
Container(
width: double.infinity,
decoration: const BoxDecoration(
color: Colors.white,
borderRadius:
BorderRadius.vertical(bottom: Radius.circular(20))),
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
children: const [
ListTile(
leading: Icon(Icons.ac_unit),
title: Text("something"),
),
ListTile(
leading: Icon(Icons.ac_unit),
title: Text("something"),
),
ListTile(
leading: Icon(Icons.ac_unit),
title: Text("something"),
),
ListTile(
leading: Icon(Icons.ac_unit),
title: Text("something"),
)
],
),
),
)
],
),
),
);
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: Scaffold(
body: SafeArea(
child: Stack(
children: [pageDesign(), customDropDown()],
),
),
),
);
}
fakeWidget(color) => Container(
height: 100,
width: double.infinity,
color: color,
child: const Center(
child: Text("widget1"),
),
);
Widget pageDesign() => Column(
children: [
/* you should control this size in diffrent orientation and for big size

const SizedBox(

I'm trying to delete the Null Container in SliverGrid.count after validated the map entries . I wish the issue arrive you . thanks in advance for you solution .
class myGridItem extends StatefulWidget {
final Item item;
final EdgeInsets? margin;
const myGridItem({
Key? key,
required this.item,
this.margin,
}) : super(key: key);
#override
_myGridItemState createState() => _myGridItemState();
}
class _myGridItemState extends State<myGridItem> {
#override
Widget build(BuildContext context) {
return Container(
margin: widget.margin == null ? EdgeInsets.zero : widget.margin,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(7),

],
),
child: Column(

children: [
Container(

],
),
),
Padding(
padding: const EdgeInsets.all(16.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
widget.item.name,
style: TextStyle(

fontSize: 13,
height: 1.5,
),
),
SizedBox(
height: 10,
),
Wrap(
spacing: 3,
crossAxisAlignment: WrapCrossAlignment.center,
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text(

}
}
Here the creation of SliverGrid.count to display the items I tried to use SliverChildBuilderDelegate but the same issue after some Editing on it to reach the same level of SliverGrid.count .
class myCartItemDisplay extends StatefulWidget {
#override
_myCartItemDisplayState createState() => _myCartItemDisplayState();
}
class _myCartItemDisplayState extends State<myCartItemDisplay> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: myAppBar(
title: 'Cart',
myBarColor: Colors.white,
mybackWidget: HomeScreen(),
),
bottomNavigationBar: AppBottomNavigation(),
backgroundColor: Colors.white,
body: SafeArea(
child: CustomScrollView(
slivers: [
Container(
child: SliverGrid.count(
crossAxisCount: 2,
childAspectRatio: 0.65,
mainAxisSpacing: 16,
crossAxisSpacing: 16,
children: Fake.furniture.asMap().entries.map((f) {
return Container(
child: f.value.addToCart == 1
? myGridItem(
item: f.value,
margin: EdgeInsets.only(
left: f.key.isEven ? 16 : 0,
right: f.key.isOdd ? 16 : 0,
))
: null,
);
}).toList(),
),
),
],
),
),
);
}
}
You can add a filter before your map:
children: Fake.furniture.asMap().entries
.where((f) => f.value.addToCart == 1)
.map((f) {
return Container(
child: myGridItem(
item: f.value,
margin: EdgeInsets.only(
left: f.key.isEven ? 16 : 0,
right: f.key.isOdd ? 16 : 0,
),
),
);
}).toList(),
This way you won't end up with any null entries in the first place.
I fixed it by add a new List it has my target entries
List<Item> _names = Fake.furniture.where((i) => i.addToCart == 1).toList();
And then :
_names.asMap().entries.map((f)
But if you have another solution with flutter give us it , thanks
Good Evening fellow Developers,
I am trying to find a way for my parent container to have its height set to be equal to the child text widget content.
The text (textDes) in the Text widget is changing. It can be short or long and for that reason I can not set the height: to a specific number like 1400 because it will look ugly.
Please be so kind and help me, trying for hours.
import 'package:angelbay_bungalows/screens/overview.dart';

Amenities(this.titleTop, this.textDes, this.img);

Wrap your Text widget inside an Expanded and remove the hardcoded height of 1400
Expanded(
child: Text(
textDes,
style: TextStyle(
fontSize: 16.0,
color: Color.fromRGBO(117, 117, 117, 1),
