Flutter Neumorphism UI

A Flutter package for building beautiful Neumorphic (soft-UI) interfaces with minimal code. It provides a clean, simple API with smart shadow auto-computation — no need to manually specify shadow colors every time.

Features

• FlutterNeumorphism — new simple widget, just pass a child and an optional NeumorphismStyle
• NeumorphismStyle — bundles all styling; auto-computes light/dark shadows from the base color
• NeumorphismType.flat — raised / embossed look
• NeumorphismType.pressed — inset / debossed look (great for active/toggle states)
• BoxShape.circle support — circular neumorphic buttons and avatars
• Optional onTap — add interaction only when needed
• Auto-sized containers — width and height are optional; widget sizes to content
• Fully backward-compatible with the original FlutterNeumorphisms widget

---

Installation

Add to your pubspec.yaml:

dependencies:
  flutter_neumorphism_ui: ^1.0.2

Then import:

import 'package:flutter_neumorphism_ui/flutter_neumorphism_ui.dart';

Quick Start

Minimal example (auto shadows, sizes to content)

FlutterNeumorphism(
  child: Text('Hello Neumorphism'),
)

Card

FlutterNeumorphism(
  style: NeumorphismStyle(
    color: Color(0xFFE8EDF2),
    borderRadius: 20,
    depth: 8,
  ),
  padding: EdgeInsets.all(20),
  child: Text('Card'),
)

Circular button

FlutterNeumorphism(
  style: NeumorphismStyle(
    color: Color(0xFFE8EDF2),
    shape: BoxShape.circle,
    depth: 8,
  ),
  width: 60,
  height: 60,
  padding: EdgeInsets.zero,
  onTap: () {},
  child: Icon(Icons.play_arrow_rounded),
)

Pressed / active state (toggle)

FlutterNeumorphism(
  style: NeumorphismStyle(
    color: Color(0xFFE8EDF2),
    depth: isActive ? 3 : 8,
    type: isActive ? NeumorphismType.pressed : NeumorphismType.flat,
  ),
  onTap: () => setState(() => isActive = !isActive),
  child: Icon(Icons.lightbulb_rounded),
)

Custom shadow colors

FlutterNeumorphism(
  style: NeumorphismStyle(
    color: Color(0xFFE8EDF2),
    lightShadow: Colors.white,
    darkShadow: Color(0xFFB8C0CC),

    borderRadius: 24,
  ),
  child: Text('Custom shadows'),
)

Legacy API

The original FlutterNeumorphisms widget is still available and unchanged for backward compatibility:

FlutterNeumorphisms(
  onTap: () {},
  backgroundColor: Colors.grey.shade300,
  topLeftShadowColor: Colors.white,
  bottomRightShadowColor: Colors.grey.shade500,
  topLeftShadowBlurRadius: 15,
  bottomRightShadowBlurRadius: 15,
  topLeftShadowSpreadRadius: 1,
  bottomRightShadowSpreadRadius: 1,
  topLeftOffset: const Offset(-4, -4),
  bottomRightOffset: const Offset(4, 4),
  borderRadius: 12,
  borderWidth: 0,
  height: 100,
  width: double.infinity,
  child: Row(
    children: [
      Icon(Icons.opacity_rounded, size: 30),
      SizedBox(width: 20),
      Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          Text('Drop', style: TextStyle(fontSize: 20)),
          Text('Neumorphism', style: TextStyle(fontSize: 18)),
        ],
