Question

我刚刚启动了一个新的Flutter应用，所以蜜蜂还没有真正完成任何工作。我已将firebase_core:添加到我的pubspec.yaml文件中，没有错误，并且该应用程序可以正常启动。当我添加firebase_auth:时，会出现此错误：

Launching lib/main.dart on iPhone 11 Pro Max in debug mode...

到目前为止，该软件包还存在许多其他问题。发生什么事了？

我认为您忘记了最后（7）个步骤： https://pub.dev/packages/google_sign_in#ios-integration

您必须为每个登录方法在Info.plist中添加CFBundleTypeRoles。此示例适用于Google登录。

<!-- 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 -->

使用您的GoogleService-Info.plist中的那个REVERSED_CLIENT_ID更改

我回家可以为您提供帮助。我有同样的错误，这就是解决方法。

如果您已向Flutter项目中添加了function App() { const [cards, setCards] = useState([]); const addNewCard = cardInfo => { setCards(cards.concat(cardInfo)); }; const removeCard = key => { setCards(cards.slice(0, key).concat(cards.slice(key + 1, cards.length))) }; return ( <div> <Form onSubmit={addNewCard} /> <CardList cards={cards} handleClick={removeCard} /> </div> ); } const CardList = props => ( <div> {props.cards.map((card, index) => ( <Card {...card} key={index} handleClick={props.handleClick(index)} /> ))} </div> ); const Card = props => { return ( <div style={{ margin: "1em" }}> <img alt="avatar" style={{ width: "70px" }} src={props.avatar_url} /> <div> <div style={{ fontWeight: "bold" }}>{props.name}</div> <div>{props.blog}</div> <a href={props.html_url}>{props.html_url}</a> <button onClick={props.handleClick}>Delete</button> </div> </div> ); };个软件包，则应将从Firebase控制台下载的firebase添加到Xcode项目中。另外，请确保您的GoogleService-Info.plist和bundle id (com.companyname.appname) firebase iOS project相同。
