title: Connect to MongoDB Atlas with mongo_dart
body: <p>I try to connect to a MongoDB Atlas database through mongo_dart with this line of code. The provided link from MongoDB is defined by:</p>
  
  <pre><code>mongodb+srv://&lt;user&gt;:&lt;PASSWORD&gt;@test-asdf.mongodb.net/test?retryWrites=true
  </code></pre>
  
  <p>throws an "Invalid scheme" Error. When I cut out "+srv" and try to connect with: </p>
  
  <pre><code>Db db = new Db("mongodb://&lt;user&gt;:&lt;password&gt;@test-asdf.mongodb.net/test?retryWrites=true");
  </code></pre>
  
  <p>it throws a SocketException: Failed host lookup.</p>
  
  <p>Is it even possible to access to a atlas mongoDB or am I forgetting something?</p>
