当我尝试从 imagelabeler 调用 processImage() 时出现以下错误如他们的文档中所述，我已经添加了依赖项，但它似乎仍然没有工作。
错误

我使用图像贴标机的功能。
Future<void> _labelScanner() async{
result='';
FirebaseVisionImage visionImage = FirebaseVisionImage.fromFile(_pickedImage);
ImageLabeler labeler = FirebaseVision.instance.imageLabeler();
final List<ImageLabel> labels = await labeler.processImage(visionImage);
for(ImageLabel label in labels){
print(label.toString());
}
}
我的应用级别 build.gradle

if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)

}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

if (flutterVersionCode == null) {

flutterVersionName = '1.0'

项目级 build.gradle 文件正如他们的官方文档链接中提到的那样。我在 buildscript 和依赖部分都添加了 maven 存储库。
buildscript {
repositories {
google()
jcenter()
maven{
url 'https://maven.google.com/'
name 'Google'
}
}
dependencies {
classpath 'com.android.tools.build:gradle:4.0.2'

}
allprojects {
repositories {

jcenter()
maven{

}
}
rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}
task clean(type: Delete) {
delete rootProject.buildDir
