I'm gonna use flutter reaction button plugin on new my app.
But when I put the reaction button, and push the icon, Preview icon box is shown to right side and main view is moved to left site.1
Here is the Item Codes to show pics and reaction button.
class CommunicationItem extends StatefulWidget {
const CommunicationItem({#required this.communication});
final Communication communication;
#override
_CommunicationItemState createState() => _CommunicationItemState();
}
class _CommunicationItemState extends State<CommunicationItem> {
#override
Widget build(BuildContext context) {
return Card(
margin: const EdgeInsets.symmetric(horizontal: 10, vertical: 5),
elevation: 2,
child: ClipRRect(
borderRadius: const BorderRadius.all(Radius.circular(5)),
child: Column(
children: [
Image.asset('assets/images/showImage.png'),
spaceH8,
Padding(
padding: const EdgeInsets.symmetric(horizontal: 20),
child: Row(
children: [
FlutterReactionButtonCheck(
onReactionChanged: (reaction, index, isChecked) {
print('reaction selected index test: $index');
},
reactions: data.reactions,
initialReaction: data.defaultInitialReaction,
selectedReaction: data.reactions[0],
),
I know the other solution like this link.
https://githubmemory.com/repo/GeekAbdelouahed/flutter-reaction-button/issues/22
But I don't know the solution by codes.
Please help it.
V/r,
This happened because the transition of the CupertinoPageRoute, try to set the page transition to none.

I do not know how to correctly explain, but I'll try. On my auth page, at the top of it, I have a GIF logo (without repeat). So auth page works like this:
logo animation running (for around 3 seconds)
after 3 seconds all other content appears (thanks to delayed_display)
And all works fine. But if I logged in to the app, and press log out, I'm redirected back to the same login page (as expected), but GIF not playing again, and simply freezing on the first frame. I can assume it's probably because my GIF set up to not repeat and it cached in flutter??? But if it's cached, why do I see it at the beginning of the animation, but not the final frame???
Also not about how authentication works. I'm using GetX for state management. So basically all is moving around authUser observable from AuthenticationController, and I have a Wrapper page which checks if authUser is not null to show DashboardScreen, otherwise AuthScreen.
Here is the AuthScreen with the gif image itself:
class AuthScreen extends StatelessWidget {
AuthScreen({Key? key}) : super(key: key);
final AuthenticationController _authController =
Get.find<AuthenticationController>();
#override
Widget build(BuildContext context) {
return Scaffold(
body: SingleChildScrollView(
child: SafeArea(
child: Column(
children: [
Image.asset('assets/images/n2mu_animated_logo.gif'), <=== here is the GIF
DelayedDisplay(
delay: const Duration(seconds: 4),
child: Container(
margin: const EdgeInsets.only(top: 40, right: 20, left: 20),
child: Center(
child: Column(children: [
RichText(
text: const TextSpan(children: [
TextSpan(
text: 'Hey, let verify:',
style:
TextStyle(fontWeight: FontWeight.bold, fontSize: 22),
),
])),
Obx(() => AnimatedSwitcher(
duration: const Duration(microseconds: 300),
child: (_authController.verificationCodeSent.value ==
false)
? PhoneNumberWidget() <== widget to shop phone number input
: SmsVerificationWidget(), <== SMS verification widget
)),
])),
)),
],
),
)));
}
}
Found the solution, you should use evict() method of the AssetImage widget. Here is more info https://github.com/flutter/flutter/issues/51775#issuecomment-680997795
I am having an issue when trying to blur a container in a Row widget when the user hovers over it (on Chrome). I have a custom widget called PanelLink, which is supposed to shrink in size and blur the background when the cursor goes over it. It works, but for some reason when hovering over one it also blurs every widget to the left not just itself.
FrontPage.dart:
import 'package:flutter/material.dart';
import 'package:website_v2/CustomWidgets/PanelLink.dart';
class FrontPage extends StatefulWidget {
FrontPage();
#override
_FrontPageState createState() => _FrontPageState();
}
class _FrontPageState extends State<FrontPage> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Website'),
centerTitle: false,
backgroundColor: Colors.blue[900],
),
backgroundColor: Colors.blueGrey[900],
body: Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
PanelLink(false, 'assets/education.jpg'),
PanelLink(true, 'assets/about.jpeg'),
PanelLink(false, 'assets/projects2.jpg'),
],
),
),
);
}
}
PanelLink.dart:
import 'package:flutter/material.dart';
import 'dart:ui';
class PanelLink extends StatefulWidget {
PanelLink(this._blur, this.imageLoc);
final bool _blur;
final String imageLoc;
#override
PanelLinkState createState() => PanelLinkState(_blur, imageLoc);
}
class PanelLinkState extends State<PanelLink> {
PanelLinkState(this._blur, this.imageLoc);
bool isHovering = false;
bool _blur;
String imageLoc;
Widget build(BuildContext context) {
return Expanded(
child: InkWell(
onTap: () => null,
onHover: (hovering) {
setState(() => {isHovering = hovering});
},
child: Stack(children: [
AnimatedContainer(
duration: const Duration(milliseconds: 1000),
curve: Curves.ease,
margin: EdgeInsets.all(isHovering ? 20 : 0),
decoration: BoxDecoration(
color: Colors.black,
image: DecorationImage(
image: AssetImage(imageLoc), fit: BoxFit.cover)),
child: BackdropFilter(
filter: ImageFilter.blur(
sigmaX: isHovering ? 5 : 0, sigmaY: isHovering ? 5 : 0),
child: Container(
color: Colors.black.withOpacity(0.1),
)),
),
Text('Test')
]),
));
}
}
Here is a picture of the issue occurring. I am hovering the mouse over panel 2, but both panel 1 and 2 are blurred but not panel 3. If I hover over panel 1 only panel 1 is blurred. If I hover over panel 3, all of them are blurred.
I experimented by only making panel two have the BackdropFilter Widget, but panel 1 still got blurred when hovering over panel 2.
Since your using AnimatedContainer widget the problem might be it cant identify the difference between his child widget. Try adding a key value identifier
AnimatedContainer(
child: Container(
key: ValueKey("imageA"), //make sure that this is different on every widget, its better to passed some value here thats different on the other refactored widget
Try experimenting it might work for you
),
),
I am a newbie to Flutter and Dart, and am trying to create a clickable container class that is based on the
GestureDetector class. My code for my container is shown below:
class CustomWidget extends GestureDetector
{
final aTitle;
CustomWidget(this.aTitle)
{
onTap() {
print("$aTitle was pressed!");
}
child: new Container(
padding: const EdgeInsets.all(8),
child: Text(aTitle),
color: Colors.blueGrey[200],
);
}
}
I am attempting to display this widget in my main application screen using the following code in the body of my app widget:
body: CustomScrollView(
primary: false,
slivers: <Widget>[
SliverPadding(
padding: const EdgeInsets.all(20),
sliver: SliverGrid.count(
crossAxisSpacing: 10,
mainAxisSpacing: 10,
crossAxisCount: 2,
children: <Widget>[
CustomWidget('Test Display'),
],
),
),
],
),
I seem to have two problems: (1) my development environment is telling me that my onTap() method is "unused", indicating
that it will not capture tap events, and (2) that doesn't seem to matter much because the CustomWidget instance that I am
creating in the app widget is not appearing on my screen.
I am clearly missing something. Can someone help me correct my code so that my custom widget will be displayed and process
onTap events?
Generally speaking, the CustomWidget is a good idea, but inheritance is the wrong implementation. Flutter strongly favors composition over inheritance.
Your custom widget using composition:
class CustomWidget extends StatelessWidget {
final String title;
const CustomWidget(this.title);
#override
Widget build(BuildContext context) {
return GestureDetector(
onTap: () {
print("$title was pressed!");
},
child: new Container(
padding: const EdgeInsets.all(8),
child: Text(title),
color: Colors.blueGrey[200],
));
}
}
I am new to Flutter and trying to build a responsive web app. So far, the code I have working is when the screen shrinks in width to a certain size, the navigation bar and its items get crunched into a menu icon button (Flutter's IconButton). This works. What doesn't work is when I click the IconButton, the new navigation bar doesn't pop up, even though the console shows I'm clicking on it. DrawerItem() is just a Text Widget wrapped in a Container. After the couple sections of code, you can see the console spitting out a response. I do not get any errors on screen or in the console when I adjust the screen size or when I click the IconButton. I've also tried making the MNavigationBar a stateful widget and adding setState to the onPressed attribute, nothing changes from the current issue and the same thing happens.
class MNavigationBar extends StatelessWidget {
const MNavigationBar({Key key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Container(
height: 80,
child: Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
IconButton(
icon: Icon(
Icons.menu,
),
onPressed: () {
NavigationDrawer();
print('Menu Icon pressed');
},
),
NavBarLogo(),
],
),
);
}
}
class NavigationDrawer extends StatelessWidget {
const NavigationDrawer({Key key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Container(
width: 260,
decoration: BoxDecoration(
color: Colors.white,
boxShadow: [
BoxShadow(
color: Colors.black,
blurRadius: 16,
),
],
),
child: Column(
children: <Widget>[
NavigationDrawerHeader(),
DrawerItem('Home'),
DrawerItem('Events'),
NavBarMenuDropdown(),
DrawerItem('Store'),
DrawerItem('Partners'),
DrawerItem('About Us'),
],
),
);
}
}

Thank you, Afridi Kayal! I did exactly what you said and it works great! See the answer in the code below...
In my main Scaffold widget, I added this code and also added logic with a ResponsiveBuilder
return ResponsiveBuilder(
builder: (context, sizingInformation) => Scaffold(
drawerEnableOpenDragGesture: false,
drawer: sizingInformation.deviceScreenType == DeviceScreenType.Mobile
? NavigationDrawer()
: null,
In my MNavigationBar, I modified this.
onPressed: () {
Scaffold.of(context).openDrawer();
print('Menu Icon pressed');
},
I'm working on my first Flutter app (debugging on my Android phone). I have a list with row items. When you long-press the row, it copies the content into the user's clipboard. This is working great!
But I need to let the user know that the content was copied.
I've attempted to follow many tutorials on trying to get the row surrounded by a build method or inside a Scaffold, but I can't get any to work. Is there an alternative method to notifying the user (simply) that something like "Copied!" took place?
Notice the commented out Scaffold.of(... below. It just seems like there must be an easier method to notifying the user other than wrapping everything in a Scaffold. (and when I try, it breaks my layout).
import 'package:flutter/material.dart';
import 'package:my_app/Theme.dart' as MyTheme;
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/services.dart';
class RowRule extends StatelessWidget {
final DocumentSnapshot ruleGroup;
RowRule(this.ruleGroup);
_buildChildren() {
var builder = <Widget>[];
if (!ruleGroup['label'].isEmpty) {
builder.add(new Text(ruleGroup['label'],
style: MyTheme.TextStyles.articleContentLabelTextStyle));
}
if (!ruleGroup['details'].isEmpty) {
builder.add(new Text(ruleGroup['details'],
style: MyTheme.TextStyles.articleContentTextStyle));
}
return builder;
}
#override
Widget build(BuildContext context) {
return new GestureDetector(
onLongPress: () {
Clipboard.setData(new ClipboardData(text: ruleGroup['label'] + " " + ruleGroup['details']));
// Scaffold.of(context).showSnackBar(SnackBar
// (content: Text('text copied')));
},
child: Container(
margin: const EdgeInsets.symmetric(vertical: 3.0),
child: new FlatButton(
color: Colors.white,
padding: EdgeInsets.symmetric(horizontal: 0.0),
child: new Stack(
children: <Widget>[
new Container(
margin: const EdgeInsets.symmetric(
vertical: MyTheme.Dimens.ruleGroupListRowMarginVertical),
child: new Container(
child: Padding(
padding: EdgeInsets.symmetric(horizontal: 32.0, vertical: 8.0),
child: new Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: _buildChildren(),
),
)),
)
],
),
),
));
}
}
The goal is to have a page like this (see image), which I have, and it works and scrolls...etc, but I cannot get it to work with a Scaffold, and therefore, haven't been able to use the snackbar. Each "Row" (which this file is for) should show a snackbar on longPress.
You can use GlobalKey to make it work the way you want it.
Since I don't have access to your database stuff, this is how I gave you an idea to do it. Copy and paste this code in your class and make changes accordingly. I also believe there is something wrong in your RowRule class, can you just copy the full code I have given you and run?
void main() => runApp(MaterialApp(home: HomePage()));
class HomePage extends StatelessWidget {
final GlobalKey<ScaffoldState> _key = GlobalKey();
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Color(0xFFFFFFFF).withOpacity(0.9),
key: _key,
body: Column(
children: <Widget>[
Container(
color: Color.fromRGBO(52, 56, 245, 1),
height: 150,
alignment: Alignment.center,
child: Container(width: 56, padding: EdgeInsets.only(top: 12), decoration: BoxDecoration(shape: BoxShape.circle, color: Colors.yellow)),
),
Expanded(
child: ListView.builder(
padding: EdgeInsets.zero,
itemCount: 120,
itemBuilder: (context, index) {
return Container(
color: Colors.white,
margin: const EdgeInsets.all(4),
child: ListTile(
title: Text("Row #$index"),
onLongPress: () => _key.currentState
..removeCurrentSnackBar()
..showSnackBar(SnackBar(content: Text("Copied \"Row #$index\""))),
),
);
},
),
),
],
),
);
}
}
These is a simple plugin replacement for the Snackbar named "Flushbar".
You can get the plugin here - https://pub.dartlang.org/packages/flushbar
You don't have to take care of any wrapping of widgets into scaffold also you get a lot of modifications for you like background gradient, adding forms and so on into Snackbar's and all.
Inside your onLongPressed in GestureDetectore you can do this.
onLongPressed:(){
Clipboard.setData(new ClipboardData(text: ruleGroup['label'] + " " + ruleGroup['details']));
Flushbar(
message: "Copied !!",
duration: Duration(seconds: 3),
)..show(context);
}
This will display the snackbar in you app where you would want to see it also you can get a lot of modification available to you so the you can make it look as per your app.
There are couple of things you need to do, like use onPressed property of the FlatButton it is mandatory to allow clicks, wrap your GestureDetector in a Scaffold. I have further modified the code so that it uses GlobalKey to make things easy for you.
Here is the final code (Your way)
class RowRule extends StatelessWidget {
final GlobalKey<ScaffoldState> globalKey = GlobalKey();
final DocumentSnapshot ruleGroup;
RowRule(this.ruleGroup);
_buildChildren() {
var builder = <Widget>[];
if (!ruleGroup['label'].isEmpty) {
builder.add(new Text(ruleGroup['label'], style: MyTheme.TextStyles.articleContentLabelTextStyle));
}
if (!ruleGroup['details'].isEmpty) {
builder.add(new Text(ruleGroup['details'], style: MyTheme.TextStyles.articleContentTextStyle));
}
return builder;
}
#override
Widget build(BuildContext context) {
return Scaffold(
key: globalKey,
body: GestureDetector(
onLongPress: () {
Clipboard.setData(new ClipboardData(text: ruleGroup['label'] + " " + ruleGroup['details']));
globalKey.currentState
..removeCurrentSnackBar()
..showSnackBar(SnackBar(content: Text('text copied')));
},
child: Container(
margin: const EdgeInsets.symmetric(vertical: 3.0),
child: new FlatButton(
onPressed: () => print("Handle button press here"),
color: Colors.white,
padding: EdgeInsets.symmetric(horizontal: 0.0),
child: new Stack(
children: <Widget>[
new Container(
margin: const EdgeInsets.symmetric(vertical: MyTheme.Dimens.ruleGroupListRowMarginVertical),
child: new Container(
child: Padding(
padding: EdgeInsets.symmetric(horizontal: 32.0, vertical: 8.0),
child: new Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: _buildChildren(),
),
),
),
)
],
),
),
),
),
);
}
}
I made a dropdown banner package on pub that allows you to easily notify users of errors or confirmation of success. It's a work in progress as I continue to add visually rich features.
I am not sure if your build() method is completed or you are yet to change it, because it consist of many widgets which are just redundant. Like there is no need to have Container in Container and further Padding along with a FlatButton which would make complete screen clickable. Also having Column won't be a good idea because your screen may overflow if you have more data. Use ListView instead.
So, if you were to take my advice, use this simple code that should provide you what you are really looking for. (See the build() method is of just 5 lines.
class RowRule extends StatelessWidget {
final GlobalKey<ScaffoldState> globalKey = GlobalKey();
final DocumentSnapshot ruleGroup;
RowRule(this.ruleGroup);
_buildChildren() {
var builder = <Widget>[];
if (!ruleGroup['label'].isEmpty) {
builder.add(
ListTile(
title: Text(ruleGroup['label'], style: MyTheme.TextStyles.articleContentLabelTextStyle),
onLongPress: () {
globalKey.currentState
..removeCurrentSnackBar()
..showSnackBar(SnackBar(content: Text("Clicked")));
},
),
);
}
if (!ruleGroup['details'].isEmpty) {
builder.add(
ListTile(
title: Text(ruleGroup['details'], style: MyTheme.TextStyles.articleContentTextStyle),
onLongPress: () {
globalKey.currentState
..removeCurrentSnackBar()
..showSnackBar(SnackBar(content: Text("Clicked")));
},
),
);
}
return builder;
}
#override
Widget build(BuildContext context) {
return Scaffold(
key: globalKey,
body: ListView(children: _buildChildren()),
);
}
}
I read your comments on all answers and here is my conslusion:
You need ScaffoldState object that is just above the widget in tree to show Snackbar. You can either get it through GlobalKey as many have suggested. Fairly simple if the Scaffold is created inside build of the widget, but if it is outside the widget (in your case) then it becomes complicated. You need to pass that key, wherever you need it through Constructor arguments of child widgets.
Scaffold.of(context) is a very neat way to just do that. Just like an InheritedWidget, Scaffold.of(BuildContext context) gives you access of the closest ScaffoldState object above the tree. Else it could be a nightmare to get that instance (by passing it through as constructor arguments) if your tree was very deep.
Sorry, to disappoint but I don't think there is any better or cleaner method than this, if you want to get the ScaffoldState that is not built inside build of that widget. You can call it in any widget that has Scaffold as a parent.
