dependencies:
  async_wallpaper: ^3.1.0

Usage

import 'package:async_wallpaper/async_wallpaper.dart';

Set wallpaper from URL

final WallpaperResult result = await AsyncWallpaper.setWallpaper(
  const WallpaperRequest(
    target: WallpaperTarget.both,
    sourceType: WallpaperSourceType.url,
    source: 'https://example.com/wallpaper.jpg',
    goToHome: true,
  ),
);

if (!result.isSuccess) {
  debugPrint('Wallpaper failed: ${result.error?.message}');
}

Set wallpaper from file

final WallpaperResult result = await AsyncWallpaper.setWallpaper(
  WallpaperRequest(
    target: WallpaperTarget.home,
    sourceType: WallpaperSourceType.file,
    source: '/storage/emulated/0/Download/wallpaper.jpg',
  ),
);

Set live wallpaper

final WallpaperResult result = await AsyncWallpaper.setLiveWallpaper(
  const LiveWallpaperRequest(
    filePath: '/storage/emulated/0/Download/live.mp4',
    goToHome: false,
  ),
);

Open wallpaper chooser

await AsyncWallpaper.openWallpaperChooser();

Start wallpaper rotation (Android only)

final WallpaperResult result = await AsyncWallpaper.startWallpaperRotation(
  const WallpaperRotationRequest(
    sources: <WallpaperRotationSource>[
      WallpaperRotationSource(
        sourceType: WallpaperSourceType.url,
        source: 'https://example.com/wallpaper1.jpg',
      ),
      WallpaperRotationSource(
        sourceType: WallpaperSourceType.file,
        source: '/storage/emulated/0/Download/wallpaper2.jpg',
      ),
    ],
    target: WallpaperTarget.both,
    intervalMinutes: 60,
    order: WallpaperRotationOrder.shuffle,
    triggers: <WallpaperRotationTrigger>{
      WallpaperRotationTrigger.interval,
      WallpaperRotationTrigger.charging,
      WallpaperRotationTrigger.timeOfDay,
    },
    activeHoursStart: 6,
    activeHoursEnd: 23,
  ),
);

Notes:

• Minimum interval is 15 minutes.
• URL entries are cached locally before rotation starts.
• Rotation runs from local files only.
• Charging trigger rotates when power is connected.
• Time-of-day trigger rotates only between activeHoursStart and activeHoursEnd.

Rotation controls

await AsyncWallpaper.rotateWallpaperNow();
await AsyncWallpaper.getWallpaperRotationStatus();
await AsyncWallpaper.stopWallpaperRotation();

Material You support check

final MaterialYouSupport support = await AsyncWallpaper.checkMaterialYouSupport();

Migration from 2.x

• HOME_SCREEN, LOCK_SCREEN, BOTH_SCREENS are replaced by WallpaperTarget enum.
• previous bool-based setter methods are replaced with typed request APIs.
• internal toasts were removed; handle UX messaging in your app.
