Select file using this code and my file in _image now I try to store using path_provider and dart.io but I can't get save methodology.

Using await ImagePicker.pickImage(...), you are already on the right track because the function returns a File.

The File class has a copy method, which you can use to copy the file (which is already saved on disk by either the camera or by lying in gallery) and put it into your application documents directory:

// using your method of getting an image
final File image = await ImagePicker.pickImage(source: imageSource);

// getting a directory path for saving
final String path = await getApplicationDocumentsDirectory().path;

// copy the file to a new path
final File newImage = await image.copy('$path/image1.png');

setState(() {
  _image = newImage;
});

You should also note that you can get the path of the image file from ImagePicker using image.path, which will also contain the file ending that you might want to extract and you can save your image path by using newImage.path.
