void getImage(ImageSource imageSource) async { PickedFile imageFile = await picker.getImage(source: imageSource); if (imageFile == null) return; File tmpFile = File(imageFile.path); final appDir = await getApplicationDocumentsDirectory(); final fileName = basename(imageFile.path); localFile = await tmpFile.copy('${appDir.path}/$fileName'); setState(() { _image = localFile; }); }
