title: type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'FutureOr<List<dynamic>>'
body: <p>I have a Problem with my json.decode.
  I want to get some data from my website but when my website says {&quot;Number&quot;:5} i only get this error (type '_InternalLinkedHashMap&lt;String, dynamic&gt;' is not a subtype of type 'FutureOr&lt;List&gt;').</p>
  <p>However if my website says string{&quot;Number&quot;:5} i get the correct output and this error FormatException: Unexpected character (at character 1).</p>
  <p>Here is my Flutter code:</p>
  <pre><code>@override
  void initState() {
  
  
  Future&lt;List&gt; senddata() async {
    final response = await http.post(&quot;http://www.quyre.de/2/Home.N.php&quot;, body: {
      &quot;status&quot;: &quot;0&quot;,
      &quot;nam_ersteller&quot;: &quot;Quyre&quot;,
    });
  
    var datauser = json.decode(response.body);
    return datauser;
  }
  
  senddata();
  }
  </code></pre>
  <p>Thanks for any answer</p>
