Вопрос:
Я пытаюсь использовать MLKit в своем приложении flutter. Я следовал инструкциям SDK, и мое приложение отлично работает с распознаванием текста. Но когда я загружаю изображение и нажимаю enter для метки изображения, оно выходит. Функция для маркировки изображений является:
//image_label_recognition
processImageLabels() async {
FirebaseVisionImage myImage = FirebaseVisionImage.fromFile(_userImageFile!);
ImageLabeler labeler = FirebaseVision.instance.imageLabeler();
_imageLabels = await labeler.processImage(myImage);
result = "";
for (ImageLabel imageLabel in _imageLabels) {
setState(() {
result = result
imageLabel.text!
":"
imageLabel.confidence.toString()
"n";
});
}
}
мой app/build.gradle
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation platform('com.google.firebase:firebase-bom:28.0.1')
implementation 'com.google.android.gms:play-services-vision:20.1.3'
implementation 'com.google.firebase:firebase-analytics'
// Use this dependency to bundle the model with your app
implementation 'com.google.mlkit:image-labeling:17.0.5'
// Use this dependency to use dynamically downloaded model in Google Play Service
implementation 'com.google.android.gms:play-services-mlkit-image-labeling:16.0.5'
градация уровня проекта
classpath 'com.android.tools.build:gradle:4.1.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.3.10'
Я добавил google-сервисы.json в приложении. И инициализировал огневую базу.
Тогда в чем может заключаться возможная ошибка. Если ошибка связана с зависимостями, то почему она не возникает в случае распознавания текста?
Я также должен добавить окно терминала.
