Flutter - Flutter 升级后 AndroidManifest.xml 损坏

如何解决Flutter - Flutter 升级后 AndroidManifest.xml 损坏

我刚刚升级到 Flutter 2 并随之升级了一个应用程序。我按照所有步骤升级应用程序，但现在我似乎无法运行该应用程序，因为我的 AndroidManifest.xml 文件似乎已损坏。

这是 xml 文件（我还在出现错误的地方添加了注释）。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.finances_management">
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <application
        android:name="io.Flutter.app.FlutterApplication" <-- Unresolved class 'FlutterApplication' 
        android:label="finances_management"
        android:icon="@mipmap/ic_launcher"> <-- Cannot resolve symbol '@mipmap/ic_launcher'
        <activity
            android:name=".MainActivity" <-- Unresolved class 'MainActivity' 
            android:launchMode="singletop"
            android:theme="@style/LaunchTheme" <-- Cannot resolve symbol '@style/LaunchTheme'
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- Specifies an Android theme to apply to this Activity as soon as
                 the Android process has started. This theme is visible to the user
                 while the Flutter UI initializes. After that,this theme continues
                 to determine the Window background behind the Flutter UI. -->
            <Meta-data
              android:name="io.Flutter.embedding.android.normalTheme"
              android:resource="@style/normalTheme" <-- Cannot resolve symbol '@style/normalTheme' 
              />
            <!-- displays an Android View that continues showing the launch screen
                 Drawable until Flutter paints its first frame,then this splash
                 screen fades out. A splash screen is useful to avoid any visual
                 gap between the end of Android's launch screen and the painting of
                 Flutter's first frame. -->
            <Meta-data
              android:name="io.Flutter.embedding.android.SplashScreenDrawable"
              android:resource="@drawable/launch_background" <-- Cannot resolve symbol '@drawable/launch_background' 
              />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <!-- Don't delete the Meta-data below.
             This is used by the Flutter tool to generate GeneratedpluginRegistrant.java -->
        <Meta-data
            android:name="FlutterEmbedding"
            android:value="2" />
    </application>
</manifest>

我在其他地方看到人们只是完全重建他们的项目（例如完全生成一个新项目，从他们的 Flutter 1.x 应用程序中剥离业务逻辑并将其复制到 Flutter 2.x 应用程序）。有谁知道我的 XML 文件怎么了？

解决方法

最好的解决方案是降级 Flutter 。之后更新 AndroidManifest 文件
