App crashes if we feed pdf in ocr

[momin-mostafa]

scenario :
use google_mlkit_text_recognition version. pick a pdf file from user. And feed it through OCR. App Crashes. Need a file type validation to ensure only image files are being passed to filePathToVisionImage method here.

code that causes crash :

22 + (MLKVisionImage *)filePathToVisionImage:(NSString *)filePath {
23     UIImage *image = [UIImage imageWithContentsOfFile:filePath];
24     MLKVisionImage *visionImage = [[MLKVisionImage alloc] initWithImage:image];  // gives error in this line
25     visionImage.orientation = image.imageOrientation;
26     return visionImage;
27 }

config:

google_mlkit_text_recognition: ^0.15.0
flutter - sdk: '>=3.3.0 <4.0.0'
