Exception: The plugin firebase_admob could not be built due to the issue above.

我尝试将 gradle 版本更改为 5.1.1，但同样的错误预计将涉及其他 gradle 发行版，我也尝试运行 flutter clean 和 flutter pub cache repair 如果需要，我将分享我的代码的某些部分 此外，当我尝试添加 admob 插件和代码中所需的代码时，我遇到了这个错误

Answer 1

我通过删除 android 文件夹解决了这个问题，然后运行以下命令 flutter create . 因为我发现了类似的问题 here 然后我根据 admob 的要求修改了 android 文件夹，之后我用广告测试了我的应用程序和它工作正常，但它给了我一些错误

Plugin project :firebase_core_web not found. Please update settings.gradle.

答案是通过像这样编辑本期here中的setting.gradle文件

include ':app'

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
}
