I use this code to take a picture with the plugin image_picker:

var image = await ImagePicker.pickImage(source: ImageSource.camera);

Now I would like to save the image in the gallery directory of the device.

According to the accepted answer to this post How to Save Image File in Flutter ? File selected using Image_picker plugin, it should have been done automatically, but I do not find in the gallery the picture taken.

I already added this permission to the manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

You can use package gallery_saver https://pub.dev/packages/gallery_saver
Get image with ImagePicker and save with GallerySaver.saveImage

code snippet

void _takePhoto() async {
    ImagePicker.pickImage(source: ImageSource.camera)
        .then((File recordedImage) {
      if (recordedImage != null && recordedImage.path != null) {
        setState(() {
          firstButtonText = 'saving in progress...';
        });
        GallerySaver.saveImage(recordedImage.path, albumName: albumName)
            .then((bool success) {
          setState(() {
            firstButtonText = 'image saved!';
          });
        });
      }
    });
  }
