flutter_liquid_glass_kit 1.0.4

iOS 26 Liquid Glass UI kit — native SwiftUI bridge on iOS, graceful glassmorphism fallback on Android.

flutter_liquid_glass_kit

iOS 26 Liquid Glass UI kit for Flutter.

• iOS → native SwiftUI glass surface. iOS 26+ uses .glassEffect(); older iOS versions use the system material fallback inside that native surface.
• Android → pure-Flutter matte glass by default, or coloured glass when LiquidGlassSettings.tintColor is supplied.

Widgets

Widget	Description
LiquidGlassCard	Glass container / card
LiquidGlassButton	Pressable glass button with scale feedback
LiquidGlassNavBar	Floating glass bottom navigation bar

Quick start

import 'package:flutter_liquid_glass_kit/flutter_liquid_glass_kit.dart';

// Card
LiquidGlassCard(
  child: Text('Hello, Glass!', style: TextStyle(color: Colors.white)),
)

// Button
LiquidGlassButton(
  onPressed: () {},
  child: Text('Tap me', style: TextStyle(color: Colors.white)),
)

// Nav bar (inside a Stack)
LiquidGlassNavBar(
  currentIndex: _index,
  onTap: (i) => setState(() => _index = i),
  items: [
    LiquidGlassNavItem(icon: Icons.home, label: 'Home'),
    LiquidGlassNavItem(
      icon: Icons.search,
      label: 'Search',
      androidIcon: Text('S'),
    ),
    LiquidGlassNavItem(icon: Icons.person, label: 'Profile'),
  ],
)

Customisation

All widgets accept a LiquidGlassSettings object:

LiquidGlassCard(
  settings: LiquidGlassSettings(
    tintColor: Colors.blue,
    tintOpacity: 0.20,
    blurSigma: 28,
    borderOpacity: 0.30,
  ),
  child: ...,
)

Two built-in presets: LiquidGlassSettings.matteLight and LiquidGlassSettings.matteDark.

On Android, omit tintColor for adaptive matte glass:

LiquidGlassCard(
  settings: const LiquidGlassSettings(),
  child: ...,
)

Check rendering mode at runtime

if (isNativeLiquidGlassSupported) {
  print('Running the native iOS glass surface');
} else {
  print('Running Android Flutter glass');
}

Requirements

• Flutter ≥ 3.19
• Dart ≥ 3.0
• iOS 16+ (native material; iOS 26+ uses Liquid Glass)
