i really need a help, so every help would mean so much to me, thankyou guys
here is my app working perfectly when i run only the ReminderPage
https://i.stack.imgur.com/JqcZp.png
and here's how it look if i run it with BottomNavigationBar (the add reminder button and moon icon cant be clicked)
https://i.stack.imgur.com/9hVr8.png
Try the following code:
Navigator.of(context, rootNavigator: true).push(
MaterialPageRoute(builder: (context) => const ReminderHomePage())
);
try this
Navigator.of(context, rootNavigator: true).push(
context,
MaterialPageRoute(builder: (context) => const ReminderHomePage()),
);
What I'm trying to achieve:
Have a BottomNavigationBar widget in its own class in its own dart file called navigationBar.dart
Have a main.dart file that has a Scaffold widget that calls this class to create the BottomNavigationBar widget
Then in the main.dart file I want to be able to set the BottomNavigationBar from navigationBar.dart and I want to be able to change the body of the Scaffold widget in the main.dart file depending on which index is selected in the BottomNavigationBar widget (check the comment in the main.dart file in the body property for a better explanation)
Here is my code below so far:
navigationBar.dart
import 'package:flutter/material.dart';
import '../home.dart';
class NavigationBar extends StatefulWidget {
const NavigationBar({Key? key}) : super(key: key);
#override
State<NavigationBar> createState() => _NavigationBar();
}
class _NavigationBar extends State<NavigationBar> {
int selectedIndex = 2;
void _onItemTapped(int index) {
setState(() {
selectedIndex = index;
});
}
#override
Widget build(BuildContext context) {
return BottomNavigationBar(
items: const <BottomNavigationBarItem>[
BottomNavigationBarItem(
icon: Icon(Icons.home),
label: 'Home',
backgroundColor: Colors.red,
),
BottomNavigationBarItem(
icon: Icon(Icons.business),
label: 'Business',
backgroundColor: Colors.green,
),
BottomNavigationBarItem(
icon: Icon(Icons.school),
label: 'School',
backgroundColor: Colors.purple,
),
BottomNavigationBarItem(
icon: Icon(Icons.settings),
label: 'Settings',
backgroundColor: Colors.pink,
),
],
currentIndex: selectedIndex,
selectedItemColor: Colors.amber[800],
onTap: _onItemTapped,
);
}
main.dart
import 'package:flutter/material.dart';
import 'components/navigationBar.dart';
void main() {
runApp(const MaterialApp(home: App()));
}
class App extends StatefulWidget {
const App({Key? key}) : super(key: key);
#override
State<App> createState() => _App();
}
class _App extends State<App> {
static const List<Widget> _widgetOptions = <Widget>[
Text(
'Index 0: Home',
),
Text(
'Index 1: Business',
),
Text(
'Index 2: School',
),
Text(
'Index 3: Settings',
),
];
#override
Widget build(BuildContext context) {
const navBar = navigationBar()
return Scaffold(
appBar: AppBar(
title: const Text('Test App',
style: TextStyle(
color: Colors.white,
fontFamily: 'LogoFont',
fontSize: 30.0,
letterSpacing: 1.5)),
centerTitle: true,
backgroundColor: Colors.lightBlue[500],
elevation: 0.0,
),
backgroundColor: Colors.lightBlue[800],
body: //something like this: _widgetOptions.elementAt(navbar.selectedIndex)
),
bottomNavigationBar: navBar);
}
}
Any ideas on how I could create what I need in the bullet points? Any help would be great, thanks
I think there is no way with stateful widget but you can do this by provider, like example below.
Provider:
class MainViewProvider with ChangeNotifier ,
DiagnosticableTreeMixin{
int activeItem = 2;
changeActiveItem(int activeElement){
activeItem = activeElement;
notifyListeners();
}
}
BottomNavBar Widget:
class BotNavWidget extends StatelessWidget {
const BotNavWidget({Key? key}) : super(key: key);
get context => null;
#override
Widget build(BuildContext context) {
final watch = context.watch<ColorsProvider>();
return Container(
padding: EdgeInsets.symmetric(
horizontal: getWidth(16), vertical: getHeight(10)),
child: Container(
height: SizeConfig.height! * .1,
width: SizeConfig.width!,
decoration: BoxDecoration(
color: watch.colors[1],
borderRadius: BorderRadius.circular(getWidth(20))),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
buildIcon(watch.bottomIcons[0], context, 0),
buildIcon(watch.bottomIcons[1], context, 1),
buildIcon(watch.bottomIcons[2], context, 2),
buildIcon(watch.bottomIcons[3], context, 3),
buildIcon(watch.bottomIcons[4], context, 4),
],
),
),
);
}
buildIcon(ColorFiltered icon, BuildContext context, int i) {
final read = context.read<MainViewProvider>();
final watch = context.watch<MainViewProvider>();
final watchColors = context.watch<ColorsProvider>().colors;
return InkWell(
onTap: () async{
read.changeActiveItem(i);
},
child: Container(
padding: EdgeInsets.all(getWidth(15)),
height: SizeConfig.height! * .07,
width: SizeConfig.height! * .07,
decoration: BoxDecoration(
color: watch.activeItem == i ? watchColors[2] : Colors.transparent,
borderRadius: BorderRadius.circular(getWidth(20))),
child: SizedBox(
height: getHeight(24),
width: getHeight(24),
child: icon
),
),
);
}
}
P.S: You can use custom BottomNavigationBar Widget instead of making it manually
There're two buttons from my WelcomeScreen, when this page is loaded, two buttons will be pressed automatically.
two buttons were used by the external widget"RoundButton".
Why I knew those buttons were being pressed, because I was using print function, and I saw the first button and second button were pressed automatically and sequentially.
Navigator.pushNamed(context, LoginScreen2.id);
Navigator.pushNamed(context, RegistrationScreen.id);
Navigator.pushNamed(context, LoginScreen2.id);
Navigator.pushNamed(context, RegistrationScreen.id);
Is there any setting I should set to prevent this problem? Thank you.

You should remove brackets from RoundButton class in
onPressed: onPressed()
to
onPressed:onPressed
and add brackets to this line of code
final Function onPressed;
as here
final Function() onPressed;
I'm not sure but maybe issue occurs because of you are using onPressed: onPressed() in RoundButton.
You can use this function without brackets like this; onPressed: onPressed,

How to make the function for api call visible to the screen after button click.
Also I want to use the text field's values at the place of defalut values
Can you solve my problem? It will be very helpful if you do so. I am a newbie and learning flutter since 15 days. Help me so that I can learn it fast. Also the flutter's community is growing fast so it will be easy for me not to wait for response. Thank You.
I have created simplified, single-screen, app without any extra capabilities to solve exactly your issue. It contains two text fields, two Text widgets to display API results and a floating action button to make request.
Key concepts that you should know to make this code are http requests and asynchronous coding. Those links are good starting points for you to get a sense of what actually happens
To summarize what exactly you need:
You send request asynchronously to the API declaring function with async keyword and await keyword in front of http.get() function. This allows you to wait for the result of the request without freezing the app
When result comes back, the rest of the _getNames() function gets executed, which includes setState(). setState() rebuilds your widget and updates values in Text() widgets

How can i change the position of my text "Sito Web" on the right of the appbar? I tryid with
alignment: Alignment.TopRight
but he move it the text on the top right corner down the appbar. Here a screen of what i mean https://ibb.co/X28TzNN change the position of "Sito Web" in the position of the red cirle. That's the codes, i tryid with this method too, but can't move in the appbar. Here the file with the appbar background_image_task-9.dart
import 'package:flutter/material.dart';
class BackgroundImage extends StatelessWidget{
final Widget body;
BackgroundImage({this.body});
#override
Widget build(BuildContext context){
return Scaffold(
appBar: AppBar(
elevation: 0,
title: Text('Blumax', style: TextStyle(
fontWeight: FontWeight.w500,
fontFamily: 'DancingScript',
fontSize: 40
),),
centerTitle: false,
),
body: Stack(
children: <Widget>[Container(
decoration: BoxDecoration(
image: DecorationImage(image: AssetImage("assets/blumax.jpg"), fit: BoxFit.cover),
),
),
body
]
)
);
}
}
And here the file with the container hyperlink.dart
import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.dart';
class Hyperlink extends StatelessWidget {
final String _url;
final String _text;
Hyperlink(this._url, this._text);
_launchURL() async {
if (await canLaunch(_url)) {
await launch(_url);
} else {
throw 'Could not launch $_url';
}
}
#override
Widget build(BuildContext context) {
return InkWell(
child: Container(
alignment: Alignment(0.9, -1.0),
child: Text(
_text,
textAlign: TextAlign.right,
style: TextStyle(
fontFamily: 'RobotoMono',
fontSize: 20,
color: Colors.white,
decoration: TextDecoration.underline),
)),
onTap: _launchURL,
);
}
}
main.dart
import 'package:flutter/material.dart';
import 'background_image_task-9.dart';
import 'hyperlink.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Blumax',
debugShowCheckedModeBanner: false,
theme: ThemeData(

home: BackgroundImage(

);
}
}
You can use Row widget and use mainAxisAlignment: MainAxisAlignment.spaceBetween to render BluMax and Sito Web elements on left and right of the appbar respectively. And since you want to open a url after tapping on sito web, you can wrap that element with GestureDetector and then call launchURL method that opens required url. A working sample code is as below:
appBar: AppBar(
title: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Text('Blumax'),
GestureDetector(
child: Text('Sito Web'),
onTap: _openURL
)
],
),
centerTitle: false,
actions: <Widget>[
PopupMenuButton<int>(
itemBuilder: (context) =>
[
PopupMenuItem(
value: 1,

PopupMenuItem(

This is rendered on screen as:
...
void _openURL() async {
const url = 'https://flutter.dev';
if (await canLaunch(url)) {
await launch(url);
} else {
throw 'Could not launch $url';
}
}
I just used a text Blumax for demo, but you may replace it per your need.
Hope this answers your question.
