Question

我正在尝试创建一个简单的“使用Google登录”应用程序。 \ 我遵循以下指示： 1.在https://firebase.google.com/上注册应用 2.下载google-services.json（注册后）并将其放入myproj/android/app文件夹中 3.将apply plugin: "com.google.gms.google-services"放在myproj/android/app/build.gradle文件的末尾，然后在同一文件中编辑包名称。 4.将classpath 'com.google.gms:google-services:4.3.2'放入myproj/android/build.gradle文件的依赖项中 5.添加

firebase_core: ^0.4.0+9
#firebase_analytics: ^5.0.2

cloud_firestore: ^0.12.9+5

firebase_auth: ^0.14.0+5
google_sign_in: ^4.0.7

rxdart: ^0.22.3

进入pubspec.yaml文件 6.构建并运行应用程序

但是由于某种原因，我遇到了这个错误：

* Error running Gradle:
ProcessException: Process "D:\Projects\simple_login\android\gradlew.bat" exited abnormally:

FAILURE: Build failed with an exception.

* Where:
Build file 'D:\Projects\simple_login\android\app\build.gradle' line: 24

* What went wrong:
A problem occurred evaluating project ':app'.
> ASCII

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

更新＃2如果我应用Google Services 3.2.1，则一切正常，因此该错误是4.3.2版本的Google Services .....

Answer 1

您错过了对myproj / android / app / build.gradle的一种依赖：

dependencies {
    implementation 'com.google.firebase:firebase-core:17.2.0'
}

Answer 2

在您的 myproj / android / build.gradle 目录中

更改Google服务版本：

class Category
{
     ...
     ...
   // i assume your category primary key is `id`
     public function subs()
     {
          return $this->hasMany(SubCategory::class, 'category_id');
     }
}


class SubCategory
{
     ...
     ...
    // i assume your subs category primary key is `id`
     public function products()
     {
          return $this->hasMany(Product::class, 'subcat_id');
     }
}


class Product
{
     //
}

Flutter，添加了Google服务后，给出了Gradle错误
