This plugin saves images and videos to gallery/photos.
You need to provide a path to the file that you want to save like below:
GallerySaver.saveImage(path)
You can use this package

If you dont understand any documentation given on this page then you can simply follow the following tutorial by Johannes

I am currently building a QR Scanner App using flutter. There I want to know how to scan a QR Code and save it permanently(using shared preferences) with the Details button. Give me an example of this (there is no need to scan a Qr, there is only a simple text title and a description of how to save a circle avater).

I'm working on a project that captures a screenshot of a widget and saves it in gallery.
my problem is there is few save to gallery packages in flutter and I tries almost all of them!
they save images as jpg which adds extra black bars around my widget which I don't want them to be there.
is there any package to save images to gallery in PNG format?
I've found the solution after 2 days of struggling with that.
you should save file as PNG to device path then use image_gallery_saver
package to save it as file
File('$dir/file_name${DateTime.now()}.png').writeAsBytes(pngBytes!);
final result = await ImageGallerySaver.saveFile(imagePath);
You can save image to gallery by using Image_gallery_saver plugin.image_gallery_saver
. For the black bars , you have to make sure that the screenshot is attached to the widget , what you want it image.
await ImageGallerySaver.saveImage(uint8list blob);
I'm trying to change the background of my map and put an image instead of it.
I'm currently using map box studio so when I'm choosing a local path
(c\deskstop\toto.png), it is working on the software, so if I choose to upload my whole map style, and use my map on the internet, it doesn't work.
I choose to upload the picture in my website then I changed the URL of the path too ( toto.com\pictures\toto.png). but it is till not working
Does someone has already this problem with mapbox?
