Flutter-请确保 android 清单是有效的 XML 文档，然后重试

Question

在这里，我在运行 flutter 项目时遇到错误。

*** 解析 LocalFile 时出错：'D:\DEVELOPMENT\Paklayer\park_app\android\app\src\main\AndroidManifest.xml' 请
确保 android 清单是有效的 XML 文档，然后重试。 ***

这是我的清单

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.park_app">
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <android:usesCleartextTraffic="true">
   <application
        android:name="io.flutter.app.FlutterApplication"
        android:label="park_app"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@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"/>
            <!-- 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"/>
            <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> ```

在应用程序标记内添加此行：

  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.park_app">
        <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
        
       <application
            android:name="io.flutter.app.FlutterApplication"
            android:label="park_app"
            android:icon="@mipmap/ic_launcher"
            android:usesCleartextTraffic="true">
            <activity
                android:name=".MainActivity"
                android:launchMode="singleTop"
                android:theme="@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

                <meta-data

                  android:resource="@style/NormalTheme"/>
                <!-- Displays an Android View that continues showing the launch screen

                <meta-data
                  android:name="io.flutter.embedding.android.SplashScreenDrawable"

                    <category android:name="android.intent.category.LAUNCHER"/>
                </intent-filter>
            </activity>
            <!-- Dont delete the meta-data below.

            <meta-data
