我正在创建一个Flutter应用程序,该应用程序使用相机插件拍摄图像,然后对其进行处理。我正在使用Firebase ML Vision程序包来处理这些图像,但是当我在iPhone上运行该应用程序时,它会崩溃。
Here's an image of the stack trace
Here's an image of when I run "flutter doctor -v"
相关代码:
fetchImageAnnotations(File image) async {
final FirebaseVisionImage visionImage =
FirebaseVisionImage.fromFile(image);
final BarcodeDetector barcodeDetector =
FirebaseVision.instance.barcodeDetector();
final LabelDetector labelDetector =
FirebaseVision.instance
.labelDetector(LabelDetectorOptions(confidenceThreshold: 0.80));
final TextDetector textDetector =
FirebaseVision.instance.textDetector();
final List<Barcode> barcodes = await barcodeDetector.detectInImage(visionImage);
final List<Label> labels = await labelDetector.detectInImage(visionImage);
final List<TextBlock> blocks = await textDetector.detectInImage(visionImage);
}
如果有人可以提供帮助,将不胜感激。
