No error display...

I used this code but Android 6 to downward its not set wallpaper await WallpaperManager.setWallpaperFromFile( file.path, WallpaperManager.HOME_SCREEN);

I am getting this MissingPluginException error while using method setwallpaperfromasset, setwallpaperfromfile works fine, please tell me solution, my device is android running with API 29

Note: C:\Users\athul\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\wallpaper_manager-1.0.7\android\src\main\java\com\mulgundkar\wallpaper_manager\WallpaperManagerPlugin.java uses or overrides a deprecated API.

Some users with Redmi Note 8 in my app are reporting this kind of error (set lock screen not working) , only happens in Lock Screen and only with this smartphone, with other phones are okay. Home Screen also are okay.

  String path = file.path;
  int location = WallpaperManager
      .HOME_SCREEN; // or location = WallpaperManager.LOCK_SCREEN;
  String result;
  try {
    result = await WallpaperManager.setWallpaperFromFile(path, location);
  } on Exception {
    result = 'Failed to get wallpaper.';
  }

No effect when I set the LOCK_SCREEN status

why?

try {
  result = await WallpaperManager.setWallpaperFromAsset(
      assetPath, WallpaperManager.LOCK_SCREEN);
} on PlatformException {
  result = 'Failed to get wallpaper.';
}

It would be useful to have a constant like WallpaperManager.BOTH, so we could set both lock screen and home screen in one method call. I think this may also be a workaround for #6.

When I load low quality image (< 200 KB) it sets properly, but when I want to set larger image (600+ KB),sometimes it doesn't load image at all, at times does or loads with black rectangles (not full image).

i am trying to set wallpaper without being scrolled here is my function

var data = jsonDecode(dat);
    var aspectRatio = data['aspectRatio'];
    if (data['type'] == 1) {
      try {
        String url = data['url'];
        int location = WallpaperManager.HOME_SCREEN;
        File file = await DefaultCacheManager().getSingleFile(url);
        var decodedImage = await decodeImageFromList(file.readAsBytesSync());
        print(decodedImage.height);

        final String result =
            await WallpaperManager.setWallpaperFromFileWithCrop(
                file.path,
                location,
                0,
                0,
                (aspectRatio * decodedImage.width).toInt(),
                (( aspectRatio) * decodedImage.height).toInt());
        print(result);
      } on PlatformException {
        print('Failed to get wallpaper.');
      }

  i searched alot but i can't find a way to centralize it 
  thx in advance
