i wanna convert my photo from gallery to File i need that beacause i will take the image to firebase when i try convert to File, it will throw me error The argument type 'String' can't be assigned to the parameter type 'List'
My code:
File? _imageFile;
final picker = ImagePicker();
Future getImage() async{
final photo = await _picker.pickImage(source: ImageSource.gallery);
_imageFile=File(photo!.path,""); #that line give error
}
EDIT: I DELETE "import 'dart:html';" and it work
To pick image
final XFile? pickedFile = await ImagePicker().pickImage(
source: ImageSource.gallery,
);
And use like
if(pickedFile !=null) Image.file(File(pickedFile.path)),
Image.file(File(pickedFile.path))///I used this code for image picking and uploading the image to firebase
File? _image;
final picker = ImagePicker();
///pop-up to choose camera gallery while uploading image

}
try use if to make a function return File
if (picedfile!= null) {
return File(picedfile.path);
}
""._imageFile=File(photo!.path);. Try this"", getting the same error? It's not possible unless you are using the same variable name (_imageFile) in somewhere else which has the type ofList<Object>. Maybe checking other codes helps.
