AndroidManifest.xml未知属性报错与应用主屏幕图标缺失问题求助

我用Android Studio开发的Flutter项目可以正常运行，但遇到两个问题：

• AndroidManifest.xml文件中多个属性被下划线标注，鼠标悬停时提示“未知属性”，但这些属性根据官方文档是合法的。
• 应用安装后，启动图标仅出现在应用托盘，未显示在主屏幕。

以下是我的相关文件和信息，恳请帮忙解决：

AndroidManifest.xml代码 #

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.sevocab">

    <uses-sdk android:minSdkVersion="21"
        android:targetSdkVersion="33"/>

   <application
        android:label="SE Vocab"
        android:name="${applicationName}"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:exported="true"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"

            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"
              />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <action android:name="android.intent.action.VIEW" />
                <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>
