<h1>Flutter ignoring header x-firebase-locale because its value was null</h1>
<p>When making a request to a Firebase service using the Flutter application, the header x-firebase-locale is usually included to indicate the desired localization for the response. However, if the value of this header is null, Flutter will ignore it and proceed with the request.</p>
<p>Here's an example of a request made with a null x-firebase-locale:</p>
<pre>
<code>
GET /example/api/endpoint HTTP/1.1
Host: example.com
Content-Type: application/json
x-firebase-locale: null
</code>
</pre>
<p>In this case, the x-firebase-locale is included in the request header, but since its value is null, it will be ignored by the Firebase service.</p>
