🛠️ How to Use

🔹 Set Wallpaper from Cached Network Image

To set a wallpaper from a remote image URL using caching, integrate the flutter_cache_manager:

Step 1: Add dependency

dependencies:
  flutter_cache_manager: ^any

Step 2: Import packages

import 'dart:io';
import 'package:flutter_cache_manager/flutter_cache_manager.dart';
import 'package:wallpaper_manager_plus/wallpaper_manager_plus.dart';

Step 3: Example code

try {
  String imageUrl = 'https://example.com/image.jpg';
  File file = await DefaultCacheManager().getSingleFile(imageUrl);

  await WallpaperManagerPlus().setWallpaper(
    file,
    WallpaperManagerPlus.homeScreen,
  );
} catch (e) {
  print('Error: $e');
}

🔹 Set Wallpaper from Local File

Use a file from local storage:

try {
  File imageFile = File('/storage/emulated/0/Download/image.png');

  await WallpaperManagerPlus().setWallpaper(
    imageFile,
    WallpaperManagerPlus.homeScreen,
  );
} catch (e) {
  print('Error: $e');
}

🔹 Set Live Wallpaper (Video)

Set a video file as a live wallpaper. The system wallpaper picker will open for manual confirmation.

From Local File:

try {
  File videoFile = File('/storage/emulated/0/Download/video.mp4');
  
  await WallpaperManagerPlus().setLiveWallpaper(videoFile);
} catch (e) {
  print('Error: $e');
}

Download and Set from URL:

import 'package:flutter_cache_manager/flutter_cache_manager.dart';

try {
  String videoUrl = 'https://www.pexels.com/download/video/7121778/';
  File videoFile = await DefaultCacheManager().getSingleFile(videoUrl);
  
  await WallpaperManagerPlus().setLiveWallpaper(videoFile);
} catch (e) {
  print('Error: $e');
}

📌 User interaction is required to complete the wallpaper setup through the system picker.
