badges 4.0.1

A package for creating badges. Badges can be used for an additional marker for any widget, e.g. show a number of items in a shopping cart.

Installing:

In your pubspec.yaml

dependencies:
  badges: ^4.0.0

Attention! Material ships its own Badge widget, so to escape the ambiguous imports you need to import the package like this:

Option 1: namespace prefix

import 'package:badges/badges.dart' as badges;

and then use the "badges.Badge" widget instead of the "Badge" widget. The same for all the classes from this package.

Option 2: hide Flutter's Material Badge widget

import 'package:badges/badges.dart';
import 'package:material_ui/material_ui.dart' hide Badge;
// or, if your app hasn't migrated to material_ui yet:
// import 'package:flutter/material.dart' hide Badge;

Basic Usage:

    badges.Badge(
      badgeContent: Text('3'),
      child: Icon(Icons.settings),
    )

Advanced usage

    badges.Badge(
      position: badges.BadgePosition.topEnd(top: -10, end: -12),
      showBadge: true,
      ignorePointer: false,
      onTap: () {},
      badgeContent:
          Icon(Icons.check, color: Colors.white, size: 10),
      badgeAnimation: badges.BadgeAnimation.rotation(
        animationDuration: Duration(seconds: 1),
        colorChangeAnimationDuration: Duration(seconds: 1),
        loopAnimation: false,
        curve: Curves.fastOutSlowIn,
        colorChangeAnimationCurve: Curves.easeInCubic,
      ),
      badgeStyle: badges.BadgeStyle(
        shape: badges.BadgeShape.square,
        badgeColor: Colors.blue,
        padding: EdgeInsets.all(5),
        borderRadius: BorderRadius.circular(4),
        borderSide: BorderSide(color: Colors.white, width: 2),
        borderGradient: badges.BadgeGradient.linear(
            colors: [Colors.red, Colors.black]),
        badgeGradient: badges.BadgeGradient.linear(
            colors: [Colors.blue, Colors.yellow],
            begin: Alignment.topCenter,
            end: Alignment.bottomCenter,
        ),
        elevation: 0,
      ),
      child: Text('Badge'),
    ),

onTap: when the badge sits outside its child (negative position values), the badge adds padding around the child so the whole badge can be tapped. Flutter only delivers taps inside a widget's bounds. The padding makes the widget bigger, so leave onTap null if you don't need it.

ignorePointer: true lets taps pass through the badge to the widgets below it (and onTap is not called).
