我想创建一个文本ocr应用程序，并且使用了flutter和firebase ml视觉。
我想阅读文字时遇到一个例外。
我已将我的应用迁移到androidx并检查了Firebase和Gradle版本。
我可以构建没有任何Gradle问题的应用程序，并且该应用程序也可以启动。
但是如上所述，问题在阅读文本时就开始了。
您可以在下面查看我的代码和错误。
请帮助我，因为我尝试修复超过6个小时。
我的代码：
Future pickImage() async {
File pickedImage = await ImagePicker.pickImage(
source: ImageSource.gallery,);
setState(() {
fileImage = pickedImage;
isImageLoaded = true;
});
}
Future readText() async {
FirebaseVisionImage ourImage = FirebaseVisionImage.fromFile(fileImage);
TextRecognizer recognizeText = FirebaseVision.instance.textRecognizer();
VisionText readText = await recognizeText.processImage(ourImage);
for (TextBlock block in readText.blocks) {
for (TextLine line in block.lines) {
for (TextElement word in line.elements) {
print(word.text);
}
}
}
}
错误：
