Installation

dependencies:
  desktop_lyrics: ^0.0.1

Quick Start

import 'package:desktop_lyrics/desktop_lyrics.dart';

final lyrics = DesktopLyrics();

void onLyricsChanged() {
  final enabled = lyrics.state.interaction.enabled;
  // update UI with state fields
}

lyrics.addListener(onLyricsChanged);

await lyrics.apply(
  lyrics.state.copyWith(
    interaction: lyrics.state.interaction.copyWith(
      enabled: true,
      clickThrough: false,
    ),
    text: lyrics.state.text.copyWith(fontSize: 34),
    background: lyrics.state.background.copyWith(opacity: 0.93),
    layout: lyrics.state.layout.copyWith(overlayWidth: 980),
  ),
);

await lyrics.render(
  const DesktopLyricsFrame.line(
    currentLine: 'Never gonna give you up',
    lineProgress: 1.0,
  ),
);

lyrics.removeListener(onLyricsChanged);
lyrics.dispose();

Karaoke Frames

Use DesktopLyricsFrame.fromTimedTokens:

final frame = DesktopLyricsFrame.fromTimedTokens(
  tokens: const [
    DesktopLyricsTokenTiming(text: 'Never ', duration: Duration(milliseconds: 700)),
    DesktopLyricsTokenTiming(text: 'gonna ', duration: Duration(milliseconds: 600)),
    DesktopLyricsTokenTiming(text: 'give ', duration: Duration(milliseconds: 500)),
    DesktopLyricsTokenTiming(text: 'you up', duration: Duration(milliseconds: 700)),
  ],
  lineProgress: 0.45,
);
await lyrics.render(frame);

Or use timeline tokens:

final frame = DesktopLyricsFrame.fromKaraokeTimeline(
  position: position,
  tokens: const [
    DesktopLyricsTimelineToken(
      text: 'Ne',
      start: Duration.zero,
      end: Duration(milliseconds: 250),
    ),
    DesktopLyricsTimelineToken(
      text: 'ver ',
      start: Duration(milliseconds: 250),
      end: Duration(milliseconds: 700),
    ),
  ],
);
await lyrics.render(frame);

   • git push origin v0.0.1
3. The desktop_lyrics_publish workflow will run and publish automatically.

Trusted Publisher setup (one-time on pub.dev):

Notes

• Linux known issue: overlay size/position does not automatically follow system scaling or resolution changes (can occur on both X11 and Wayland).
