title: StreamBuilder and AsyncSnapshot + rxdart flutter question
body: <p>I have <code>final _fetcher = PublishSubject&lt;MyModel&gt;() ;</code> in my bloc Component. Here is structure of <code>MyModel</code>:</p>
  
  <pre><code>MyModel { List&lt;MyObjects&gt; _objects = []; 
  List&lt;MyObjects&gt; get allObjects =&gt; _objects; }
  </code></pre>
  
  <p>also there is </p>
  
  <pre><code>Observable&lt;MyModel&gt; get myObjects =&gt; _fetcher.stream;
  </code></pre>
  
  <p>in bloc.  </p>
  
  <p>I have two pages, first displays list of <code>MyObjects</code> inside <code>Listview.builder</code>, and second displays selected <code>MyObject</code> data.<br>
  I'm trying to get data from <code>myObjects</code> using <code>StreamBuilder</code>.<br>
  In the first page all objects displays perfectly. But when I open a page with selected object, my <code>AsyncSnapshot</code> inside <code>StreamBuilder</code> always has <code>connections.state</code> waiting, although I have data in stream.<br>
  What am I doing wrong?</p>
