无法找到构建Flutter项目时显示的firebase_core FlutterFire插件错误

Question

我在构建颤振项目时出现以下错误：*评估项目"：firebase_ml_vision"时出现问题。

找不到firebase_core FlutterFire插件，您是否已将其作为依赖项添加到您的pubspec*中

这是否意味着我必须安装一些额外的库？我只想在我的项目中使用ML Vision。谢谢你的帮助。

我的pubspec.yaml文件：

dependencies:
flutter:
sdk: flutter
get: ^3.24.0
firebase_ml_vision: ^0.11.0
image_picker: ^0.6.3+4
image_cropper: 1.0.2

build.gradle(应用程序(：

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
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.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}

将firebase_core添加到您的项目中。
