Я добавил mlkit в свой проект флаттера, и он создает исключение при сборке. Файл dart и файлы pubspec.yaml, похоже, не содержат ошибок.
Я попытался изменить некоторые вещи в файлах build.gradle, однако это не сработало, поэтому я вернул их в исходное состояние
Код дротика выглядит следующим образом:
import 'package:flutter/material.dart';
import 'dart:io';
import 'dart:ui' as ui;
import 'package:firebase_ml_vision/firebase_ml_vision.dart';
import 'package:image_picker/image_picker.dart';
import 'package:mlkit/mlkit.dart';

@override

);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
File _imageFile;
List<Face> _faces;
List<VisionLabel> _currentLabels = <VisionLabel>[];
bool isLoading = false;
ui.Image _image;
_getImageAndDetectFacesAndObjects() async {
final imageFile = await ImagePicker.pickImage(source: ImageSource.camera);
setState(() {
isLoading = true;
});
final image = FirebaseVisionImage.fromFile(imageFile);
FirebaseVisionLabelDetector detector = FirebaseVisionLabelDetector.instance;
final faceDetector = FirebaseVision.instance.faceDetector();
List<Face> faces = await faceDetector.processImage(image);
List<VisionLabel> currentLabels =
await detector.detectFromBinary(imageFile?.readAsBytesSync());
if (mounted) {

}
}
