A custom navigation bar with bubble click effect in Flutter
License: MIT License
I'm a software engineer at PayPal in Chicago, IL 🌆
I am getting this exception when testing my application with your navigation included. Which does not happen if I use a different one. Yet, I couldn't figure out the issue. The dispose() method is not getting called in the CostumeNavigationBarState when I debug it. Since, I am new to flutter you might have a better idea, where this comes from.

Hello, i found one issue, which doesn't let me implement this widget to my app.
When i switching between tabs quickly, animation of icon growing isn't fully animated and icon remains large
When I remove the title property (CustomNavigationBarItem) on iphone 11, there is a space above it. but no problem on iphone 7 plus.
But if I set it to Title('') the problem goes away. This time the problem is on iphone 7.
Code:
@override
Widget build(BuildContext context) {
return KeyboardDismissOnTap(
child: Scaffold(
bottomNavigationBar: MyBottomNavigationBar(),
body: pages[_selectedIndex],
),
);
}
Widget MyBottomNavigationBar() {
return CustomNavigationBar(
elevation: 5,
bubbleCurve: Curves.linear,
iconSize: 28.0,
selectedColor:
Theme.of(context).bottomNavigationBarTheme.selectedItemColor ??
Colors.black,
strokeColor: Color(0x30040307),
unSelectedColor:
Theme.of(context).bottomNavigationBarTheme.unselectedItemColor ??
Colors.black38,
backgroundColor:
Theme.of(context).bottomNavigationBarTheme.backgroundColor ??
Colors.white,
borderRadius: Radius.circular(10.0),
items: [
CustomNavigationBarItem(
icon: Icon(LineIcons.home),
title: Text(""),
),
CustomNavigationBarItem(
icon: Icon(LineIcons.search),
title: Text(""),
),
CustomNavigationBarItem(
icon: Icon(LineIcons.plusCircle),
// title: Text(""),
),
CustomNavigationBarItem(
icon: Icon(LineIcons.bell),
// title: Text(""),
),
CustomNavigationBarItem(
icon: Icon(LineIcons.userCircle),
// title: Text(""),
),
],
currentIndex: _selectedIndex,
onTap: (index) {
setState(() {
_selectedIndex = index;
});
},
);
}I think there is a minor bug when disposing the widget.
I paste here the log if you want to have a look.

is it possible to add swipe pages with his bar. if yes please tell how
Thank you for this great package.
Feature Request
Would it be possible to increase the gesture area for each CustomNavigationBarItem ? For example the CupertinoTabScaffold 's TabBar takes on the default behaviour of not only tapping on the Icon itself, but rather tapping on the Icon and its relative surrounding.
This makes it easier for users to easily change tabs without aiming directly for the Icons or better still, expose the animations to a CupertinoTabScaffold.
Hi , great job but i want to use svg with SvgPicture rather than IconData. I don't know if is possible to use both of them.
Thanks
Hi, just wonder it's that possible add a blur effect to navbar background? that would looks nice on iOS apps.
So I have 3 NavbarItems all with a title of text. In the first one the text is longer, pushing the other 2 off center and to the side.
So instead of
---1---2---3---
its
---1----2---3--
Which seems odd since there is more than enough space for all 3 text widgets
I want to use elevation but it doesn't work for me. I tried on emulator and real device but no results. how can i use ? Thank you
Facing Null Safety support issue for v2.12.0. Please update the code as per requirement.
don't support null safety:
- package:custom_navigation_bar
I was wondering if it is possible to set the width of the floating navbar?
Navbar that I have now:
CustomNavigationBar( selectedColor: Color(0xFF279B40), strokeColor: Color(0xFF279B40), unSelectedColor: Colors.grey[600], backgroundColor: Colors.white, items: [ CustomNavigationBarItem( icon: Icon(Icons.notifications), title: Text("Meldingen", style: TextStyle(fontSize: 12, fontWeight: FontWeight.w600),), ), CustomNavigationBarItem( icon: Icon(Icons.home), title: Text("Dashboard", style: TextStyle(fontSize: 12, fontWeight: FontWeight.w600),), ), ], currentIndex: _activeIndex, onTap: (page) { _controller.animateToPage( page, duration: const Duration(milliseconds: 250), curve: Curves.fastOutSlowIn, ); }, borderRadius: Radius.circular(16.0), isFloating: true, ),
Is it possible to add a circular border on the top left and top right?
Example:
return Container(
color: themeData.settingsListBackground,
width: MediaQuery.of(context).size.width,
alignment: Alignment.center,
child: ConstrainedBox(
constraints: BoxConstraints(maxWidth: 810),
child: SettingsTheme(
themeData: themeData,
platform: platform,
child: ListView.builder(
physics: physics,
controller: xxxxxxxxx,
shrinkWrap: shrinkWrap,
itemCount: sections.length,
padding: contentPadding ?? calculateDefaultPadding(platform),
itemBuilder: (BuildContext context, int index) {
return sections[index];
},
),
),
),
);
this component so good to me , but demo on iOS with dark mode look like not so well.
Due changes in flutter_icons this:
AntDesign.getIconData('shoppingcart')
Needs to be change to:
AntDesign.shoppingcart
And this other part:
onChanged: (ThemeStyle value) { setState(() { _currentStyle = value; }); }
Doesn't compile either, it needs "ThemeStyle ?" and
ThemeStyle? _currentStyle = ThemeStyle.NotificationBadge;
Also, the package flutter_icons is not null safety so, impossible to execute the example
