How to convert String List to String in flutter? : <p>I need to convert List into string in dart.</p>

<p>i want to extract the value of list from preferences. I have tried this implementation but it is only giving me the last value.</p>

<pre><code>   Future&lt;List&lt;String&gt;&gt; 
    services=SharedPrefSignUp.getSelectedServices();
     services.then((onValue){
  List&lt;String&gt;servicesList=onValue;
  selectServicesText=servicesList.join(",");
});
</code></pre>
