一、创建数据库

二、对使用不同提供方的账号登录的用户进行身份验证和管理，而无需服务器端代码

三、添加依赖 google_sign_in

1、如果您需要向后端服务器进行身份验证，您可以在 GoogleService-Info.plist 中添加 SERVER_CLIENT_ID 键值对。 SERVER_CLIENT_ID可以从 iOS 应用对应的GoogleService-Info.plist 文件中获取到。

2、然后将下面的 CFBundleURLTypes 属性添加到 [my_project]/ios/Runner/Info.plist 文件中。

<!-- Put me in the [my_project]/ios/Runner/Info.plist file -->
<!-- Google Sign-in Section -->
<key>CFBundleURLTypes</key>
<array>
	<dict>
		<key>CFBundleTypeRole</key>
		<string>Editor</string>
		<key>CFBundleURLSchemes</key>
		<array>
			<!-- TODO Replace this value: -->
			<!-- Copied from GoogleService-Info.plist key REVERSED_CLIENT_ID -->
			<string>com.googleusercontent.apps.861823949799-vc35cprkp249096uujjn0vvnmcvjppkn</string>
		</array>
	</dict>
</array>
<!-- End of the Google Sign-in Section -->

3、作为将 GoogleService-Info.plist 添加到 Xcode 项目的替代方法，您可以在 Dart 代码中配置应用程序。 在这种情况下，请跳过步骤 3 到 7，并将 clientId 和 serverClientId 传递给 GoogleSignIn 构造函数：

GoogleSignIn _googleSignIn = GoogleSignIn(
  ...
  // The OAuth client id of your app. This is required.
  clientId: ...,
  // If you need to authenticate to a backend server, specify its OAuth client. This is optional.
  serverClientId: ...,
);

1、在 firebase 中添加项目 项目名：flutter-firebase-chat

2、配置项目

➜ firebase_chat git:(main) ✗ flutterfire configure

完成后会在对 ios、andorid、web 三个平台生成对应的配置文件. ios: GoogleService-Info.plist android: google-services.json web:

备注：在我的应用中，iOS、Android 两个应用分别有 GoogleService-Info.plist 和 google-services.json 文件，需要下载到本地，与之前自动生成的文件进行对比，如果不同，则需要手动替换。

3、添加依赖

  # Firebase Core 的 Flutter 插件，可连接到多个 Firebase 应用程序。
  firebase_core: ^2.15.1
  # 适用于 Firebase Auth 的 Flutter 插件，支持使用密码、电话号码和 Google、Facebook 和 Twitter 等身份提供商进行 Android 和 iOS 身份验证。
  firebase_auth: ^4.9.0

4、iOS、Android 真机运行 结果：均运行 OK。
