}
return NewsLoading(text: '1');
}
When I tap first or second item on the there is no reaction from UI. It seems onTap does not navigate to different pages.
Could you please help me why this code is not working?
Edit: I think the problem causing Scaffold body. Current Scaffold body is:
body: TabBarView(
children: [
for (final tab in filteredList)
NewsView(
id: tab.id!,
),
],
),
How can I integrate showPage(_selectedIndex), into Scaffold Body without hurt the TabbarView?
here is the TabBarController
return DefaultTabController(
// length: snapshot.data!.data!.length,
length: filteredList.length,
child: Scaffold(
appBar: AppBar(
backgroundColor: (Colors.white),
iconTheme: const IconThemeData(color: Colors.black),
title: Transform.translate(
offset: const Offset(-24.0, 0.0),
child: Image.asset("assets/images/lo.png",
fit: BoxFit.contain, height: 22),
),
bottom: PreferredSize(
preferredSize: const Size.fromHeight(30.00),
child: ColoredBox(
color: Colors.white,

indicatorColor: Colors.purple,
isScrollable: true,

I would like to create a home page for my flutter app. I used templates from the network, but unfortunately I don't get it the way I sketched it in the picture. maybe someone can help me with that
sketch / result
Unfortunately, I'm sure that I can't do it better: - /, would like to have it exactly like the one on the left (icons and colors are not so important)
I used this link from the forum as a template for the appbar, and I had difficulties in inserting it ^^
Custom AppBar Flutter
I also got the code for the BottomNavigationBar from somewhere in the forum, but I think this is not suitable for my purposes anyway. Since I don't like this shrink effect when clicking on it, the two arrow buttons at the edge should snap back when pressed and not stay in the pressed state, as they should stand for the front and back function ...

I have modified your code with some commentaries to support you in building the UI.
For the AppBar, you are going in the right direction of using PreferredSize with Stack, just some minor adjustments.
For the BottomNavigationBar, since the provided BottomNavigationBarItem has the icon and title attributes already, we can use that and modify the color from their parents. The 2 arrows buttons can be placed together within the Row.
Here's the full example:
import 'package:flutter/material.dart';

I need to build a BottomNavigationBar with a text and a number as the photo below :
the name of the tab is will shown just when the app is active
how to do it ??
Basically this is exactly what you want: https://flutterawesome.com/a-modern-google-style-nav-bar-for-flutter/
I recomend you extracting this code and build it to your fits.
import 'package:flutter/material.dart';

import 'package:line_icons/line_icons.dart';
void main() => runApp(MaterialApp(

home: Example()));
class Example extends StatefulWidget {
#override
_ExampleState createState() => _ExampleState();

int _selectedIndex = 0;

static const List<Widget> _widgetOptions = <Widget>[

'Index 0: Home',
style: optionStyle,
),
Text(
'Index 1: Likes',
style: optionStyle,
),
Text(
'Index 2: Search',
style: optionStyle,
),
Text(
'Index 3: Profile',
style: optionStyle,
),
];
#override

I'm having a problem right now in my bottom navigation in flutter.
I have four navigation "Community, Feeds, Activity, Profile".
In my "Feeds" navigation I have a button named "View Profile" everytime I click that button it directs me to a new screen using
"Navigator.push(context, MaterialPageRoute())"
and I notice it auto generates a "<-" or "back arrow" icon on the appbar.
The problem is everytime I click that "back arrow", it redirects me to the first option on my navigation bar.
Not on the "Feeds" navigation.
Any tips how to fix this?
Here is my bottom navigation code:
_getPage(int page) {
switch (page) {
case 0:
return NewsFeed();
case 1:
return OrgAndNews();
case 2:
return MyActivity();
case 3:
return Profile();
}
}
int currentPage = 0;
void _onBottomNavBarTab(int index) {
setState(() {
currentPage = index;
});
}
return Scaffold(
body: Container(
child: _getPage(currentPage),
),
bottomNavigationBar: Container(
height: _height * .09,
child: BottomNavigationBar(

Have you used MaterialPage Route With Builder Like This?
Navigator.push(

You will have to add your way back to the stack.
Try the below appbar in you 'tuloung duloung' title page, it should do the trick.
Note if your homescreen has tabs its advised to pass the index of the page you want to reach on exiting 'tuloung duloung'.
Let me know if it helps.
