Issue
I'm trying to convert an image or XFile from image_picker to an inputImage for a different library. The full error message is: ======== Exception caught by gesture =============================================================== The following _TypeError was thrown while handling a gesture: type 'Future< dynamic>' is not a subtype of type 'XFile'
These are the 3 methods that I've been using to do this. I've tried several things, but I keep getting this error.
GetImage() async {
print("getImage");
final ImagePicker _picker = ImagePicker();
final XFile? photo = await _picker.pickImage(source: ImageSource.camera);
return photo;
}
changeFile(XFile image) async{
File? file = File(image!.path);
return file;
}
getData(File file) async{
TextRecognition textRecognition = TextRecognition();
//final inputImage = _processImageFile(image);
final inputImage = InputImage.fromFile(file);
var result = await textRecognition.process(inputImage);
print(result);
}
I call it with:
XFile photo = GetImage();
File file = changeFile(photo);
getData(file);
The error message says that it's on the line
XFile photo = GetImage();
I tried adding more functions, adding the async, and I tried changing
File file = File(image.path);
to
File? file = File(image!.path);
Solution
Try to convert into Future method and await for photo.
Future<XFile?> GetImage() async {
print("getImage");
final ImagePicker _picker = ImagePicker();
final XFile? photo = await _picker.pickImage(source: ImageSource.camera);
return photo;
}
Now call this method with await
XFile? photo = await GetImage(); /// convert it to async method, and this will provide nullable file
