AndroidManifest is givin me multiple error-CodePudding

I am having multiple error regarding following AndroidManifest.xml these are the error. I am flutter bigginer, and couldn't understand reading similer posts.

・Unresolved class '{applicationName}' ・Attribute android:usesCleartextTraffic is not allowed here ・Attribute android:icon is not allowed here ・Unresolved class 'MainActivity' ・Attribute android:launchMode is not allowed here ・Attribute android:theme is not allowed here ・Attribute android:configChanges is not allowed here ・Attribute android:hardwareAccelerated is not allowed here ・Attribute android:windowSoftInputMode is not allowed here ・Attribute android:allowBackup is not allowed here ・Attribute android:fullBackupContent is not allowed here

What I have tried so far is invalidate cache and remove all of them and re-add lines. Do you know what is to be fixed?

         additional functionality it is fine to subclass or reimplement
         FlutterApplication and put your custom class here. -->

Your manifest should look something like this

<?xml version="1.0" encoding="utf-8"?>
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:versionCode="1"
    android:versionName="1.0">

    <!-- Beware that these values are overridden by the build.gradle file -->
    <uses-sdk android:minSdkVersion="15" android:targetSdkVersion="26" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <!-- This name is resolved to com.example.myapp.MainActivity
             based upon the namespace property in the `build.gradle` file -->
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

Unfortunately you have placed most of your property in disarray

CodePudding user response：

The Error is in the application name. android:name="${applicationName} is not valid or has access to applicationName Variable. Application Name must be a string.
