Overview

bottom_navigation_badge / BottomNavigationBadge

BottomNavigationBadge is a Flutter class developed by westdabestdb.

Getting Started

Add this to your package's pubspec.yaml file:

...
dependencies:
  bottom_navigation_badge: ^1.0.3

Now in your Dart code, you can use:

import 'package:bottom_navigation_badge/bottom_navigation_badge.dart';

Usage

Initialize the badger. Isn't it a nice variable name lol 😁

BottomNavigationBadge badger = new BottomNavigationBadge(
  backgroundColor: Colors.red,
  badgeShape: BottomNavigationBadgeShape.circle,
  textColor: Colors.white,
  position: BottomNavigationBadgePosition.topRight,
  textSize: 8);

Create a list of BottomNavigationBarItems

List<BottomNavigationBarItem> items = [
  BottomNavigationBarItem(icon: Icon(Icons.home), title: Text("Home")),
  BottomNavigationBarItem(icon: Icon(Icons.notifications), title: Text("Notifications")),
  BottomNavigationBarItem(icon: Icon(Icons.face), title: Text("Profile"))
];

Add badge to index with content "1"

setState(() {
  items = badger.setBadge(items, "1", index);
});

Remove the badge at index

setState(() {
  items = badger.removeBadge(items, index);
});

Remove all the badges

setState(() {
  items = badger.removeAll(items);
});

Badge is giving padding on top

Implemented this plugin, it gives bottom overflowby 12 px, tried resizing title text, warning does not go. anyhelp would be appreciated. thanks in advance

A Major Update (50%+ code re-write)
Changes:

delete duplicate labels see (https://github.com/westdabestdb/bottom_navigation_badge/pull/10)

migrate to support null-safety

fix major bugs

removeAll not actually removing every badge (if you have 2 layers of the badge)

allowing multiple layers of the badge is a bad idea

update example

All changes above are extensively tested on the example.

I will be happy to take on maintaining this package if you wish.
