Same here, but with pictures. If I try to save multiple images in sync they work fine. But if it’s in parallel, it crashes the app.

Works:

 
static Future<List<bool?>> downloadAllImages(List<String> urls) async {
  final distinctUrls = urls.toSet().toList();

  final results = <bool?>[];
  for (var url in distinctUrls) {
    final result = await GallerySaver.saveImage(url);
    results.add(result);
  }
  return results;
 }

Crashs the app:

static Future<List<bool?>> downloadAllImages(List<String> urls) async {
  final distinctUrls = urls.toSet().toList();

  return Future.wait(distinctUrls.map(GallerySaver.saveImage));
}

I have exactly the same behavior as @carlosfiori. Would be great if there was a method that took a list of paths/urls.
