android - 为flutter项目添加Firebase无法正常工作

Question

我遵循了一些教程，将Firebase添加到我的flutter项目中。但是，无论我做什么，我的项目都会引发同样的错误并完全失败。
我尝试创建新项目，但同样失败。
我正在关注tutorial。
进行更改并输入命令flutter run之后，这一次又一次给了我同样的错误。
输出:

Launching lib/main.dart on ASUS X00TD in debug mode...
Running Gradle task 'assembleDebug'...
Plugin project :firebase_core_web not found. Please update settings.gradle.
Plugin project :firebase_auth_web not found. Please update settings.gradle.

尝试添加
下面的代码在flutter app-> android-> settings.gradle

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}
