setWallpaper method

@override Future<bool> setWallpaper(File imageFile, int location)

Sets the wallpaper from an image file at a specified location.

This method converts the given image file to bytes and sends it via a platform channel to set it as the wallpaper.

imageFile is the image file that will be converted to bytes and used as the wallpaper. location specifies the location where the wallpaper should be set. It can be:

• home screen
• lock screen
• both screens

Implementation

@override
Future<bool> setWallpaper(File imageFile, int location) async {
  try {
    if (!await imageFile.exists()) {
      throw Exception("Image file does not exist: ${imageFile.path}");
    }

    // Read image bytes in an isolate to prevent blocking the UI thread
    Uint8List imageBytes = await _readFileBytesInIsolate(imageFile.path);

    // Send byte data and location to platform channel to set wallpaper
    return await methodChannel.invokeMethod('setWallpaper', {
      'imageBytes': imageBytes,
      'location': location,
    });
  } catch (e) {
    // Catch any errors during the process and return a failure
    if (e is FileSystemException) {
      throw Exception("Failed to read the image file: ${e.message}");
    } else if (e is PlatformException) {
      throw Exception("Failed to set wallpaper: ${e.message}");
    } else {
      throw Exception("An unexpected error occurred: $e");
    }
  }
