i am trying to update the state of the animated switcher in the middle area. i am trying to do this using a setstate in the lower area. but it does not work.
the first thing i did is to create a variable with a boolean data type in the home class.
then i passed the variable to both the middle area and the lower area
the idea was that if the same variable is passed to the class whose state i am trying to update, and the class with the set state, it would work. but it seems i am wrong. i would appreciate some assistance.
the boolean variable i am trying to make work is the _rep variable
This is the Home widget
class HomePage extends StatefulWidget {
const HomePage({Key? key}) : super(key: key);
#override
State<HomePage> createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> with TickerProviderStateMixin {

_anime = Tween<Offset>(

use provider pacakges https://pub.dev/packages/provider
Create a class that inherits the functions of ChangeNotifyer to create a flag to control and create a setter.
provider class
class StateController extends ChangeNotifier{
bool _req = false;
bool get req => _req; //getter
setReqValue(){
_req = !_req;
notifyListener();
}
}
Declare the provider class in the main function. You can change the location of the declaration according to Wiget tree, but first declare it in main
Change main.dart
void main(){
runApp(
Multiprovider(
providers: [
ChangeNotifierProvider(create: (_) => StateController()),
],
child: HomePage(),
)
);
}
The UI is updated by notifyListener().
change UI
child: context.watch<StateController>().req == true ? Padding(
padding: const EdgeInsets.all(14.0),
key: const Key('1'),
child: Container(
height: 40,
width: 40,
decoration: BoxDecoration(
border: Border.all(
color: Colors.brown.shade300,
width: 3
),
borderRadius: BorderRadius.circular(10)
),
child: const Center(
child: Icon(
Icons.coffee_outlined,
size: 20,
),
)
),
):null,
Change State
onTap: (){
widget.controller.forward();
setState(() {
_bigger = !_bigger;
_fade = !_fade;
context.read<StateController>().setReqValue();
print('this is fade $_fade ');
});
},
I am too lazy to try understand your code. But if you want to update state of the page after you pop from Navigation to it.
In page you want to update
Navigation.push(context, /* Page that will change something */)
// Future will trigger then you return to this page.
.then((_) => setState(() {}))

in above code i think there might be the issues between the usage of SviverToBoxAdapter what widget should i use instead to achieve the required design
I want the dialog to open when a button is clicked, but an error occurs due to BLoC. Previously, there was such an error with the class itself, but I successfully solved it, and in this case, the complexity already arises. I've already tried a couple of options but couldn't solve it. I tried to make the event in onPressed as a separate widget, and the same error did not work either.

You have to use MultiBlocProvider before MaterialApp.
just do like that
#override
Widget build(BuildContext context) => MultiBlocProvider(
providers: [
BlocProvider(create: (_) => TodoBloc()),
],
child: MaterialApp()
);
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,

];
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(

child: Row(
children: [
SizedBox(

}
Widget pickedEmpty() {
return Text(

fontWeight: FontWeight.w400,
),
);
}
Widget pickedNotEmpty() {
List<Widget> list = <Widget>[];
for (var i = 0; i < picked.length; i++) {
list.add(

overlayEntry?.remove();
},

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(

Hi I have designed a screen in flutter. I have AlertDialog on which I want to close the dialog and screen on pressing. Right now AlertDialog dismiss on press but screen is not closing.
Does anyone know how to do this ?

Ideally, you'll want to call pop more than once. One for the modal, another for the actual route.
There are a few ways to achieve this. But ideally you'll want to await the close of the dialog before triggering another close:
foo() async {
await showDialog(
context: context,
builder: (context) => AlertDialog(
actions: [
new FlatButton(
child: new Text("OK"),
onPressed: () => Navigator.pop(context),
),
],
),
);
Navigator.pop(context);
}
This way, both the route and the modal can handle their close however they like.
This is how i did with mine
bool _logout = false;
and then at the start of build Widget
#override
Widget build(BuildContext context) {
return WillPopScope(
onWillPop: () async {
_onBackPressed(context);
return _logout;
},
child: Container(),
);
}
and the method _onBackPressed returns a custom dialog Class like so
void _onBackPressed(BuildContext c) async {
await showDialog(
barrierColor: CustomColors.darkGrey.withOpacity(0.8),
barrierDismissible: true,
context: context,
builder: (BuildContext context) {
return CustomDialogBox(
title: 'Logout',
description: 'Are you sure you want to logout?',
rightButtonText: 'Yes',
onPClick: () {
_logout = true;
if (_logout == true) {
Get.back();
}
},
onNClick: () {
_logout = false;
Get.back();
},
);
});
if (_logout == true) {
Get.back();
}
}
and my custom Dialog class is here
class CustomDialogBox extends StatefulWidget {
final String? title, description, leftButtonText, rightButtonText;
final VoidCallback? onPClick, onNClick;
final Image? image;
const CustomDialogBox({
Key? key,
this.title,
this.description,
this.leftButtonText,
this.rightButtonText,
this.image,
this.onPClick,
this.onNClick,
}) : super(key: key);
#override
_CustomDialogBoxState createState() =>
// ignore: no_logic_in_create_state
_CustomDialogBoxState(onPClick!, onNClick!);
}
class _CustomDialogBoxState extends State<CustomDialogBox> {
final VoidCallback onPClick, onNClick;
_CustomDialogBoxState(this.onPClick, this.onNClick);
#override
Widget build(BuildContext context) {
return Dialog(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(Dimensions.BORDER_RADIUS_4),
),
elevation: 0,
backgroundColor: Colors.transparent,
child: Container(
//height: 200,
padding: const EdgeInsets.only(
left: 10,
right: 0,
bottom: 10,
),
decoration: BoxDecoration(
shape: BoxShape.rectangle,
color: Colors.white,
borderRadius: BorderRadius.circular(8),
boxShadow: [
BoxShadow(
color: CustomColors.darkGrey,
offset: const Offset(0, 30),
blurRadius: 20,
),
]),
child: Wrap(children: <Widget>[
dialogBody(context),
]),
),
);
}
Widget dialogBody(context) {
return Column(children: [
Row(mainAxisAlignment: MainAxisAlignment.spaceBetween, children: [
Image.asset(
Images.LOGO,
height: MediaQuery.of(context).size.height * 0.035,
),
IconButton(
//padding: const EdgeInsets.all(0),
onPressed: () {
Get.back();
},
icon: const CircleAvatar(
radius: 12.5,
child: Icon(

),
]),
Padding(
padding: const EdgeInsets.only(
right: 10,
),
child: Column(children: [
//----//

text: widget.title ?? '',

fontSize: 16,

return onPClick();
},
context: context,
),
//----//
]),
),
]);
}
}
the buttons and texts are custom so feel free to change them. and where you see Get.back(); is GetX code.. you can replace with Navigator.of(context).pop();
try this
showPop() async {
await showDialog(
context: context,
barrierDismissible: true,
builder: (context) => AlertDialog(
actions: [
new FlatButton(
child: new Text("Close"),
onPressed: () => Navigator.pop(context),
),
],
),
);
}
