liquid_wave_indicator

Liquid wave fill for percent metrics (0–100 in rows, 0.0–1.0 on a single pill). You provide icons and gradients; only the animation ships with the package.

Preview

Features

• SocialMediaPill — one liquid gauge (progress 0.0–1.0)
• SocialMediaFeed / SocialMediaReachSection — horizontal rows of gauges (section adds optional heading + title)
• SocialMediaPillStyle.socialReach — tall pill preset for dense rows
• buildSocialReachItems — merge a Map<String, int> (percent values) with a config map
• Semantics: accessibility label + spoken percent

Metrics row (section + tall pills)

Optional heading, section title (default Progress), and a full-width row. Override title for your domain (e.g. 'Weekly goals', 'Social Media Reach').

import 'package:flutter/material.dart';
import 'package:liquid_wave_indicator/liquid_wave_indicator.dart';

SocialMediaReachSection(
  heading: 'Dashboard',
  title: 'This week',
  items: [
    SocialReachItem(
      label: 'Workouts',
      reach: 60,
      icon: const Icon(Icons.fitness_center, color: Colors.white),
      gradient: const LinearGradient(
        begin: Alignment.bottomCenter,
        end: Alignment.topCenter,
        colors: [Color(0xFF2E7D32), Colors.white],
      ),
    ),
    SocialReachItem(
      label: 'Focus',
      reach: 40,
      icon: const Icon(Icons.timer, color: Colors.white),
      gradient: const LinearGradient(
        begin: Alignment.bottomCenter,
        end: Alignment.topCenter,
        colors: [Color(0xFF1565C0), Colors.white],
      ),
    ),
  ],
);

The section hides when every reach is ≤ 0. Use pillStyle to change size.

With maps:

final items = buildSocialReachItems(
  reachByPlatformKey: {
    'instagram': 98,
    'tiktok': 32,
    'facebook': 85,
    'snapchat': 27,
  },
  configByPlatformKey: configMap,
);

SocialMediaReachSection(
  heading: 'Liquid Wave Indicator',
  title: 'Social Media Reach',
  items: items,
);

Quick start (centered row)

import 'package:flutter/material.dart';
import 'package:liquid_wave_indicator/liquid_wave_indicator.dart';

class MetricRowSnippet extends StatelessWidget {
  const MetricRowSnippet({super.key});

  @override
  Widget build(BuildContext context) {
    final items = [
      SocialReachItem(
        label: 'Hydration',
        reach: 72,
        icon: const Icon(Icons.water_drop, color: Colors.white, size: 22),
        gradient: const LinearGradient(
          colors: [Color(0xFF4FC3F7), Color(0xFF0288D1)],
        ),
      ),
      SocialReachItem(
        label: 'Steps',
        reach: 45,
        icon: const Icon(Icons.directions_walk, color: Colors.white, size: 22),
        gradient: const LinearGradient(
          colors: [Color(0xFF66BB6A), Color(0xFF2E7D32)],
        ),
      ),
    ];

    return SocialMediaFeed(items: items);
  }
}

Items with reach <= 0 are omitted.

Usage

Values from maps (buildSocialReachItems)

Keys are arbitrary ('north', 'premium', …). One map holds int percents, the other holds label + icon + gradient per key.

import 'package:flutter/material.dart';
import 'package:liquid_wave_indicator/liquid_wave_indicator.dart';

final valuesByKey = {
  'a': 72,
  'b': 45,
  'c': 0, // hidden in the feed
};

final uiByKey = {
  'a': SocialPlatformConfig(
    label: 'Metric A',
    icon: const Icon(Icons.star, color: Colors.white, size: 22),
    gradient: const LinearGradient(colors: [Colors.deepPurple, Colors.purple]),
  ),
  'b': SocialPlatformConfig(
    label: 'Metric B',
    icon: const Icon(Icons.bolt, color: Colors.white, size: 22),
    gradient: const LinearGradient(colors: [Colors.orange, Colors.deepOrange]),
  ),
};

final items = buildSocialReachItems(
  reachByPlatformKey: valuesByKey,
  configByPlatformKey: uiByKey,
);

SocialMediaFeed(items: items);

For SVG icons, add flutter_svg and pass SvgPicture.asset(...) as icon.

Single pill

SocialMediaPill(
  progress: 0.75,
  label: 'Storage',
  icon: const Icon(Icons.sd_storage, color: Colors.white),
  gradient: const LinearGradient(
    colors: [Color(0xFF5C6BC0), Color(0xFF3949AB)],
  ),
);

Custom size and timing

SocialMediaFeed(
  items: items,
  spacing: 10,
  padding: const EdgeInsets.symmetric(horizontal: 16, vertical: 12),
  pillStyle: SocialMediaPillStyle(
    width: 80,
    height: 60,
    percentFontSize: 13,
    waveDuration: const Duration(milliseconds: 2000),
    percentTweenDuration: const Duration(milliseconds: 600),
  ),
);

Acknowledgments

We built this package together and are happy to put it out there so other developers can add liquid-style progress UI without reinventing the wheel—less grind, more focus on what makes your app special.

George Amany and Mohameed Saleh did the hands-on work on the code and the package. Abdlrahman Ibrahem, our tech lead, guided architecture and quality. Abdalla Gad shaped the look and feel as designer. Huge thanks to everyone involved; we hope it saves you time.
