hologramism 1.0.1

Motion-reactive security-hologram (DOVID/Kinegram) widget for Flutter (iOS + Android): color-shifting foil that tilts with the device, GPU-rendered with Rust + wgpu.

hologramism (Flutter / iOS + Android)

Flutter binding for the Hologramism animated security-hologram renderer. It renders to a native GPU surface: a CAMetalLayer on iOS (the HologramismKit Swift package) and an ANativeWindow / TextureView on Android (the io.github.alexdonh:hologramism AAR). Rust + wgpu power both.

Install

flutter pub add hologramism

iOS

The native GPU engine ships separately as the prebuilt HologramismKit pod, hosted on GitHub Releases (not on CocoaPods trunk). Add one line to your app's ios/Podfile pointing at the matching release, then pod install:

pod 'HologramismKit', :podspec =>
  'https://github.com/alexdonh/hologramism/releases/download/v1.0.0/HologramismKit.podspec'

Android

The native engine ships as the io.github.alexdonh:hologramism AAR on Maven Central (the plugin pins the matching version). Just ensure mavenCentral() is in your app's repositories, with no credentials needed.

minSdk 24. There's no other setup, since the plugin registers the platform view.

Usage

import 'package:hologramism/hologramism.dart';

// Gold guilloché, transparent so it overlays anything.
SizedBox(
  width: 300, height: 190,
  child: HologramView(preset: Preset.guilloche(), color: HologramColor.gold),
);

// Tile a circle into a grid; the rainbow sweeps the whole grid as one surface.
HologramView(
  shape: HologramShape.circle(),
  preset: Preset.rainbow(),
  layout: Layout.tile(size: 0.22, gap: 0.03),
);

// Kinegram: cross-fades gold to sapphire on tilt.
HologramView(
  layers: [
    HologramLayer(preset: Preset.linear(angle: 0), color: HologramColor.gold, azimuth: 0),
    HologramLayer(preset: Preset.rosette(), color: HologramColor.sapphire, azimuth: 90),
  ],
  tilt: const Tilt(motion: true, gesture: true, autoOrbit: true),
);

Angles and azimuths are in degrees. The widget props mirror the same canonical scene schema used by every Hologramism binding. See the top-level README for the full feature list.
