title: how can i call query with a notEqual (!=) where-clause using **Flutter** cloud_firestore plugin?
body: <p>firebase team announced <a href="https://firebase.googleblog.com/2020/09/cloud-firestore-not-equal-queries.html" rel="nofollow noreferrer">in this blog post</a> that they now support <strong>notEquals</strong> in where-clause queries,</p>
  <p>how can we call such a query in flutter?
  i use the <a href="https://pub.dev/packages/cloud_firestore" rel="nofollow noreferrer">latest version</a> in pubspec.yaml:</p>
  <pre><code>cloud_firestore: ^0.14.2
  </code></pre>
  <p>for instance in firebase this is now (October 1, 2020) possible:</p>
  <pre><code>collection(&quot;projects&quot;).where(&quot;status&quot;, &quot;!=&quot;, &quot;completed&quot;)
  </code></pre>
  <p>and in flutter it's not working (too many positional arguments):</p>
  <pre class="lang-dart prettyprint-override"><code>    FirebaseFirestore.instance.collection(&quot;projects&quot;).where(&quot;status&quot;, &quot;!=&quot;, &quot;completed&quot;);
  </code></pre>
  <p>and there is no named arguments for it, the only arguments i can find:</p>
  <pre class="lang-dart prettyprint-override"><code>      Query where(
          dynamic field, {
          dynamic isEqualTo,
          dynamic isLessThan,
          dynamic isLessThanOrEqualTo,
          dynamic isGreaterThan,
          dynamic isGreaterThanOrEqualTo,
          dynamic arrayContains,
          List&lt;dynamic&gt; arrayContainsAny,
          List&lt;dynamic&gt; whereIn,
          bool isNull,
        })
  </code></pre>
  <p>does any one have a workaround / idea / solution ?</p>
