Flutter Firebase 身份验证与 Google 应用程序崩溃

Posted 2023-02-23

【中文标题】Flutter Firebase 身份验证与 Google 应用程序崩溃

【英文标题】：Flutter Firebase Authentication With Google App Crash

【发布时间】：2019-12-20 12:24:51

【问题描述】：

我正在使用 Flutter 制作“使用 Google 登录”按钮，但是当我单击该按钮时，应用程序崩溃并退出，尽管我确信 Firebase 已与应用程序正确集成，并且 SHA1 正确且应用程序可以正常工作与 Firestore 相得益彰

这里是代码和错误。

错误：

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In ios, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

# For information on the generic Dart part of this file, see the
# following page: https://dart.dev/tools/pub/pubspec

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
   - res/images/bag.jpg
   - res/images/computer.jpg
   - res/images/dress.jpg
   - res/images/phone.jpg
   - res/images/shoes.jpg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf

【问题讨论】：

您是否在 Google 控制台上填写了同意书？错误 12500。

【参考方案1】：

我遇到了同样的问题。升级到 AndroidX 解决了我的问题。 将您的 Flutter 项目升级到 androidx Android Studio 可以节省时间。

步骤：

要将项目升级到 androidx，请在 Android Studio 的 Flutter 项目中打开 android 文件夹。

从 重构 菜单中选择 迁移到 AndroidX

并应用迁移更改

运行flutter clean build

【参考方案2】：

在应用层build.gradle

 defaultConfig       

    minSdkVersion 23

在项目级别gradle.properties添加

android.useAndroidX=true
android.enableJetifier=true

在build.gradle添加

dependencies 
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.2.0'

如果您不使用 Kotlin 支持，则可以跳过该 Kotlin 插件 不要忘记运行flutter clean 然后flutter pub upgrade

这些更改帮助我防止了我的应用崩溃，它也应该对您有所帮助。

【讨论】：

这肯定有帮助。

【参考方案3】：

我正在使用 firebase_auth：^0.14.0+2 google_sign_in: ^4.0.6

应用级分级：

dependencies 
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'com.google.firebase:firebase-core:17.0.1'

收到此错误....

E/AndroidRuntime(5431): 原因: java.lang.NullPointerException: 尝试调用虚拟方法'android.view.View androidx.fragment.app.FragmentActivity.dispatchFragmentsOnCreateView(android.view.View, java.lang. String, android.content.Context, android.util.AttributeSet)' 在空对象引用上

完成： 扑干净 清理缓存 颤振升级 颤振酒吧获取

【讨论】：

你是如何清理缓存的？

C:flutter/pub-cache/hosted/../ &

我几乎尝试了 2 天来让两个版本一起工作，但失败了。所以我使用 google_sign_in: 4.0.2 & firebase_auth: ^0.11.0+7

我在 iOS 上遇到了同样的问题 .... 有没有人偶然为 iOS 解决了这个问题？
