The problem was that the <code>AndroidManifest.xml</code> file was lacking a required <code>&lt;meta-data android:name=&quot;flutterEmbedding&quot; android:value=&quot;2&quot;/&gt;</code> tag. Add it like so:
<pre><code>&lt;manifest xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
 package=&quot;com.coding.informer.simple_material_app&quot;&gt;

 &lt;uses-permission android:name=&quot;android.permission.INTERNET&quot;/&gt;
 &lt;meta-data android:name=&quot;flutterEmbedding&quot; android:value=&quot;2&quot;/&gt;

 &lt;application android:name=&quot;${applicationName}&quot; android:label=&quot;simple_material_app&quot; android:icon=&quot;@mipmap/ic_launcher&quot;&gt;
 &lt;activity android:name=&quot;.MainActivity&quot;
 android:launchMode=&quot;singleTop&quot;
 android:theme=&quot;@android:style/Theme.Black.NoTitleBar&quot;
 android:configChanges=&quot;orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection&quot;
 android:hardwareAccelerated=&quot;true&quot;
 android:windowSoftInputMode=&quot;adjustResize&quot;&gt;
 &lt;intent-filter&gt;
 &lt;action android:name=&quot;android.intent.action.MAIN&quot;/&gt;
 &lt;category android:name=&quot;android.intent.category.LAUNCHER&quot;/&gt;
 &lt;/intent-filter&gt;
 &lt;/activity&gt;
 &lt;/application&gt;
&lt;/manifest&gt;

It will inside application tag. Please see attached :<a href="https://i.stack.imgur.com/lONDN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lONDN.png" alt="enter image description here" /></a>
So your manifest fill wiil be look like this :
<pre><code>&lt;manifest xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
 package=&quot;com.coding.informer.simple_material_app&quot;&gt;

 &lt;uses-permission android:name=&quot;android.permission.INTERNET&quot;/&gt;
 

 &lt;application android:name=&quot;${applicationName}&quot; android:label=&quot;simple_material_app&quot; android:icon=&quot;@mipmap/ic_launcher&quot;&gt;
 &lt;activity android:name=&quot;.MainActivity&quot;
 android:launchMode=&quot;singleTop&quot;
 android:theme=&quot;@android:style/Theme.Black.NoTitleBar&quot;
 android:configChanges=&quot;orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection&quot;
 android:hardwareAccelerated=&quot;true&quot;
 android:windowSoftInputMode=&quot;adjustResize&quot;&gt;
 &lt;intent-filter&gt;
 &lt;action android:name=&quot;android.intent.action.MAIN&quot;/&gt;
 &lt;category android:name=&quot;android.intent.category.LAUNCHER&quot;/&gt;
 &lt;/intent-filter&gt;
 &lt;/activity&gt;


 &lt;meta-data
 android:name=&quot;flutterEmbedding&quot;
 android:value=&quot;2&quot; /&gt;

 &lt;/application&gt;

Add below code to android &gt; app &gt; src &gt;main &gt; AndroidManifest.xml
<code> &lt;meta-data android:name=&quot;flutterEmbedding&quot; android:value=&quot;2&quot; /&gt;</code>

Trying to run a Flutter application with the <code>flutter run</code> command produces the following error:
<pre><code>No `&lt;meta-data android:name=&quot;flutterEmbedding&quot; android:value=&quot;2&quot;/&gt;` in &quot;..\src\main\AndroidManifest.xml&quot;
</code></pre>
Here is my <code>AndroidManifest.xml</code> file:
<pre><code>&lt;manifest xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
 package=&quot;com.coding.informer.simple_material_app&quot;&gt;

 &lt;uses-permission android:name=&quot;android.permission.INTERNET&quot;/&gt;

 &lt;application android:name=&quot;${applicationName}&quot; android:label=&quot;simple_material_app&quot; android:icon=&quot;@mipmap/ic_launcher&quot;&gt;
 &lt;activity android:name=&quot;.MainActivity&quot;
 android:launchMode=&quot;singleTop&quot;
 android:theme=&quot;@android:style/Theme.Black.NoTitleBar&quot;
 android:configChanges=&quot;orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection&quot;
 android:hardwareAccelerated=&quot;true&quot;
 android:windowSoftInputMode=&quot;adjustResize&quot;&gt;
 &lt;intent-filter&gt;
 &lt;action android:name=&quot;android.intent.action.MAIN&quot;/&gt;
 &lt;category android:name=&quot;android.intent.category.LAUNCHER&quot;/&gt;
 &lt;/intent-filter&gt;
 &lt;/activity&gt;
 &lt;/application&gt;
&lt;/manifest&gt;
</code></pre>
I'm aware that the error message offers an obvious solution but I want to post my answer here so that anyone else running into this error can resolve it quickly.

No `<meta-data android:name="flutterEmbedding" android:value="2"/>` in "..\src\main\AndroidManifest.xml"
