I want to add an image and a text together in a card but I'm not able to do it. I think a row would be used here but not able to implement it. I'm new to flutter and app development so having some troubles. Any help is really appreciated. Also the cards are in GridView(not in ListView).

This is a variable which I'm using in the "body" of Scaffold.
If you want to place an Image and a text side by side, add a Row widget:
child: Row(
children: <Widget>[
DecorationImage(...),
Text(...),
],
)
You can also set mainAxisAlignment and crossAxisAlignment to make sure that your widgets are placed correctly
just wrap your Container into a Row Widget and add a text to it.
Row(
children: <Widget>[
Text("add text here"),
Container(
// child: SizedBox(child: Text('yashjha'),),
// child: Image.asset('lib/images/${images[index]}'),
decoration: BoxDecoration(
image: DecorationImage(
image: AssetImage('lib/images/${images[index]}'),
fit: BoxFit.fitWidth,
alignment: Alignment.topCenter,
),
),
),
],
),

I am trying to make an audio player app,
and I want to make the player screen fit the whole screen size.
However, the padding at the top and at the bottom doesn't help.
I tried to remove the SafeArea from bottomNavigationBar and other widgets and it didn't work.
How can I handle this?
Image of the player:
(the gray color padding doesn't let the image stretch to the end)
the code of the player:
Widget build(BuildContext context) {
return Scaffold(
resizeToAvoidBottomInset: false,
backgroundColor: const Color(0xff1c1c1e),
body: GetBuilder<OverlayHandler>(
builder: (getContext) {
if (!Get.find<OverlayHandler>().inPipMode) {
return Stack(
children:[
Container(...)
]
); // player at full screen
} else {
return Stack(...); // player at PiP mode
}
}
)
);
}
the code of the main screen widget:
Widget build(BuildContext context) {
return GetBuilder<NavigationController>(
builder: (controller) {
return Scaffold(
body: SafeArea(
// bottom option of this SafeArea doesn't affect the player size
child: IndexedStack(
index: controller.tabIndex,
children: const [
...
],
),
),
bottomNavigationBar: SafeArea(
// bottom option of this SafeArea doesn't affect the player size
child: SizedBox(
height: 80,
child: BottomNavigationBar(
items: [
...
],
),
),
),
);
}
);
}
}

Try removing the Scaffold()'s background color and add extendBody: true, or set the height of the container to height: double.infinity, or inside the stack just add and empty container with height as height: double.infinity,
i was searching a lot and reading a lot another threads and nothing work for my case, my background image is moving when keyboards appears. I tried my best, and I am getting frustrated already because I am wasting a lot of time, could someone help me with this?
the image goes up every time I open the textinput and the keyboard appears, I think my mistake is to position the elements in the code, or I am missing something but the truth is I can't figure out what my mistake is.
I want to add that this page" is a page of a PageView, I don't know if that will have something about causing the issue.
Cuz i switch between login and register pages with the buttons, they are a pageview.

}
PageController get pageController => this._pageController;
}
Fixed!!! i will share how i fix it for someone need this:
welcome_page.dart
#override
Widget build(BuildContext context) {
return ChangeNotifierProvider(
create: (_) => new NavegacionModel(),
child: Scaffold(
resizeToAvoidBottomInset: false, // i had to add this here, when i add here the image didnt move anymore by the keyboard
body: _Paginas(),
),
);
}
}
login_page.dart
#override
Widget build(BuildContext context) {
return Stack( // i remove this unnecesary scaffold until i need childrens, for now, i just return the stack
children: [
_crearfondo2(),
Padding( //i add this Padding cuz the form didnt scroll with the "resizeToAvoidBottomInset: false" until i add this padding here.
padding: EdgeInsets.only(
bottom: MediaQuery.of(context).viewInsets.bottom,
),
child: _loginForm(),
),
],
);
}
Try Like This
Widget build(BuildContext context) {
return MaterialApp(
title: 'flutter background',
home: Container(
decoration: BoxDecoration(
image: DecorationImage(
image: AssetImage("images/background.jpg"), fit: BoxFit.cover)),
child: Scaffold(
resizeToAvoidBottomInset: false,
backgroundColor: Colors.transparent,
appBar: AppBar(
elevation: 0,
backgroundColor: Colors.transparent,
title: Text('My App'),
centerTitle: true,
),
),
),
);
}
Use
resizeToAvoidBottomInset: false,
in the welcome page Scaffold
child: Scaffold(
body: _Paginas(),
),
I have been struggling with the problem of pushing updated data from one widget to another. This problem occurs when I have two Stateful widgets and the data is updated in the parent Stateful widget but is not updated in the child Stateful widget. The error occurs with the usage of the freezed package but also occurs without it as well.
I have not been able to find anything that fixes this as of yet.
Below is an example:
First Stateful Widget:
class FirstWidget extends StatefulWidget {
#override
_FirstWidgetState createState() => _FirstWidgetState();
}
class _FirstWidgetState extends State<FirstWidget> {
ItemBloc _itemBloc = getit<ItemBloc>();
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.black,
appBar: AppBar(
elevation: Mquery.width(context, 2.5),
backgroundColor: Colors.black
title: Text(
'First stateful widget',
style: TextStyle(fontSize: 17),
),
centerTitle: true,
),
body: BlocBuilder<ItemsBloc,ItemsState>(
cubit: _itemsBloc,
builder: (BuildContext context,ItemState state) {
return state.when(
initial: () => Container(),
loading: () => Center(child: CustomLoader()),
success: (_items) {
return AnotherStatefulWidget(
items: _items,
...
);
},
);
},
));
},
);
);
}
}
Second Stateful Widget:
class AnotherStatefulWidget extends StatefulWidget {
final List<String> items;
AnotherStatefulWidget(this.items);
#override
_AnotherStatefulWidgetState createState() => _AnotherStatefulWidgetState();
}
class _AnotherStatefulWidgetState extends State<AnotherStatefulWidget> {
final ScrollController scrollController = ScrollController();
ItemsBloc _itemsBloc = getit<ItemsBloc>();
bool _handleNotification(ScrollNotification notification, List<String> items) {
if (notification is ScrollEndNotification &&
scrollController.position.extentAfter == 0.00) {
_itemsBloc.add(ItemsLoadEvent.loadMoreItems(
categories: items, document: ...));
}
return false;
}
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.black,
body: Container(
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Container(
width: double.infinity,
height: 280,
child: Padding(
padding: EdgeInsets.only(
right: 8,
),
child: NotificationListener<ScrollNotification>(
onNotification: (_n) =>
_handleNotification(_n, widget.items),
child: DraggableScrollbar.arrows(
alwaysVisibleScrollThumb: true,
controller: scrollController,
child: ListView.builder(
controller: scrollController,
itemCount: widget.items.length,
itemBuilder: (context, index) {
return GestureDetector(
child: Padding(
padding: EdgeInsets.all(16),
child: Align(
alignment: Alignment.center,
child: Text(
widget.items[index],
style: TextStyle(color: Colors.white),
)),
),
);
},
),
),
),
),
)
],
),
),
),
);
}
}
I would really appreciate any help!
Thank you for you time,
Matt
so I am currently having a grid of pictures and I want to implement a feature from instagram: If you longPress on one of the pictures, you get a a larger version of that picture appearing in the middle of the screen. If you stop pressing, the image dissapears.
I don't really need the code for that, but I just can't think of which widgets I should use.
Is there maybe a package for something like this? If not then how can I do it with Flutter standard widgets? Maybe using a dialog that appears on the longPress ?
Here's the improved vewrsion that resembles the same exact UX as of Instagram with blurred background.
We can achieve this using a combination of Stateful Widget, Stack and BackdropFliter, here is the sample code -
import 'dart:ui';
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Counter Demo',
theme: ThemeData.light(),
home: Scaffold(
appBar: AppBar(
backgroundColor: Colors.blueGrey,
centerTitle: true,
title: Text("Demo App"),
),
body: Stacked(),
),
);
}
}
class Stacked extends StatefulWidget {
#override
_StackedState createState() => _StackedState();
}
class _StackedState extends State<Stacked> {
final List<String> images = [
"1.jpg",
"2.jpg",
"3.jpg",
"4.jpg",
"5.jpg",
"6.jpg",
"7.jpg",
"8.jpg",
"9.jpg",
"10.jpg",
];
bool _showPreview = false;
String _image = "assets/images/1.jpg";
#override
Widget build(BuildContext context) {
return SafeArea(
child: Stack(
children: [
GridView.builder(
itemCount: images.length,
gridDelegate:
SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 2),
itemBuilder: (BuildContext context, int index) {
return GestureDetector(
onLongPress: () {
setState(() {
_showPreview = true;
_image = "assets/images/${images[index]}";
});
},
onLongPressEnd: (details) {
setState(() {
_showPreview = false;
});
},
child: Padding(
padding: const EdgeInsets.all(4.0),
child: Card(
elevation: 4,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(5.0),
),
clipBehavior: Clip.hardEdge,
child: Image.asset("assets/images/${images[index]}"),
),
),
);
},
),
if (_showPreview) ...[
BackdropFilter(
filter: ImageFilter.blur(
sigmaX: 5.0,
sigmaY: 5.0,
),
child: Container(
color: Colors.white.withOpacity(0.6),
),
),
Container(
child: Center(
child: ClipRRect(
borderRadius: BorderRadius.circular(10.0),
child: Image.asset(
_image,
height: 300,
width: 300,
),
),
),
),
],
],
));
}
}
This is just a baseline example and there are endless possibilities you can modify this to achieve behavior you want.
Another simple way is we can build this by using StatefulWidget and IndexedStack -
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Counter Demo',
theme: ThemeData.light(),
home: Scaffold(
appBar: AppBar(
backgroundColor: Colors.blueGrey,
centerTitle: true,
title: Text("Demo App"),
),
body: Body(),
),
);
}
}
class Body extends StatefulWidget {
#override
_BodyState createState() => _BodyState();
}
class _BodyState extends State<Body> {
final List<String> images = [
"1.jpg",
"2.jpg",
"3.jpg",
"4.jpg",
"5.jpg",
"6.jpg",
"7.jpg",
"8.jpg",
"9.jpg",
"10.jpg",
];
int _index = 0;
String _image = "assets/images/1.jpg";
#override
Widget build(BuildContext context) {
return SafeArea(
child: IndexedStack(
index: _index,
children: [
GridView.builder(
itemCount: images.length,
gridDelegate:
SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 2),
itemBuilder: (BuildContext context, int index) {
return GestureDetector(
onLongPress: () {
setState(() {
_index = 1;
_image = "assets/images/${images[index]}";
});
},
onLongPressEnd: (details) {
setState(() {
_index = 0;
});
},
child: Padding(
padding: const EdgeInsets.all(4.0),
child: Card(
elevation: 4,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(5.0),
),
clipBehavior: Clip.hardEdge,
child: Image.asset("assets/images/${images[index]}"),
),
),
);
},
),
Container(
decoration: BoxDecoration(
color: Colors.white.withOpacity(0.2),
),
child: Center(
child: ConstrainedBox(
constraints: BoxConstraints(
maxHeight: 400,
maxWidth: 400,
),
child: Image.asset(
_image,
),
),
),
)
],
),
);
}
}
You can check output for above code here.
You could use Peek and Pop https://pub.dev/packages/peek_and_pop
Is an implementation for Flutter based on the iOS functionality of the same name.
I have a String _value, which I would like to call it from another page.
Here is my players.dart
class MyWidgetPopup extends StatefulWidget {
#override
MyWidgetPopupState createState() => MyWidgetPopupState();
}
enum Answers{FIRST,SECOND}
class MyWidgetPopupState extends State<MyWidgetPopup> {
String _value = '';
void _setValue(String value) => setState(() => _value = value);
Future selectGk(BuildContext context) async {
switch(
await showDialog(
...
...
{
case Answers.FIRST:
_setValue('FIRST TEAM');
break;
case Answers.SECOND:
_setValue('SECOND TEAM');
break;
}
}
So, in players.dart, I can show the selected team with simple code: Text(_value)
But I would like to show it in select.dart
import 'package:flutter/material.dart';
import 'package:myapp/players.dart';
MyWidgetPopupState dataSource = MyWidgetPopupState();
class Besdortbir extends StatefulWidget {
#override
_BesdortbirState createState() => _BesdortbirState();
}
class _BesdortbirState extends State<Besdortbir> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(
'My Title'),
centerTitle: true,
backgroundColor: Colors.redAccent[700],
elevation: 0.0,
),
body: Stack(
fit: StackFit.expand,
children: <Widget>[
Container(
decoration: BoxDecoration(
image: new DecorationImage(
image: new AssetImage("assets/field.png"),
fit: BoxFit.fill
)
),
),
//FIRST PLAYER
Container(
padding: EdgeInsets.only(bottom: 90.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
crossAxisAlignment: CrossAxisAlignment.end,
children: <Widget>[
GestureDetector(
onTap: (){dataSource.selectGk(context);}, //I have the FIRST TEAM and SECOND TEAM listed here.
child: Container(
child: ClipRRect(
borderRadius: BorderRadius.circular(20.0),
child: Image.asset('assets/PLUS.png',
scale: 8),
),
),
),
Text(//somehow I would like to show which team is selected by user),
],
),
),
],
),
);
}
}
I have tried to recall setState(), _value, and a few other options. But, I could not be successful.
