Flutter Android Studio 错误 - ApiException：10

Question

我已经有两天遇到同样的错误了，问题是 Android Studio 给我的唯一错误是； “谷歌：PlatformException（sign_in_failed，com.google.android.gms.common.api.ApiException：10：，null，null）”

我正在尝试使用 Firebase 登录

查了很多资料也没找到解决办法。之前它确实给了我更多的错误，但我一直在打磨它，直到只剩下这个。

我给你留下一些配置，你可以看看是否正确。

我有 firebase_options.dart，还安装了 firebase-tools-instant-win.exe，进行登录。

我的 android/build.gradle 是：

buildscript {
    ext.kotlin_version = '1.7.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.4.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.15'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

我的build.gradle是：

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'
}

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    namespace "com.example.untitled"
    compileSdkVersion flutter.compileSdkVersion
    ndkVersion flutter.ndkVersion

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.untitled"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
        minSdkVersion 20
        targetSdkVersion 34
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true

        signingConfigs {
            release {
                storeFile file("xxxxxxxxx.jks")
                storePassword 'xxxxxxx'
                keyAlias 'xxxxxxxkey'
                keyPassword 'xxxxxxx'
            }
        }
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.multidex:multidex:2.0.1'
    implementation 'com.google.firebase:firebase-analytics'
    implementation platform('com.google.firebase:firebase-bom:32.2.0')
}

我的Main调用Firebase，在Main代码中我怀疑有任何错误，它一定是外部的。由于没有出现错误并且没有 firebase YES，所以有登录

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
  runApp(const MyApp());
}

我认为问题出在凭据中，因为我无法创建“创建 OAuth 客户端 ID”，因为它告诉我“请求失败，因为 Android 包名称和指纹已在使用中”

SHA 密钥是正确的...其他一切都正确，检查了一、二、三...四次，我没有在任何地方看到任何错误。

预先感谢，抱歉我的英语！

PS：我添加了 Main 的代码，删除了所有内容（因为它是一个非常完整的代码），只留下启动会话的“逻辑”。
