+    select **Flutter**.
+
+ 1. <h3>Verify Flutter SDK setup</h3>

  1. <h3>Configure your project</h3>
+
+    Click **Next** to continue to project configuration.
+    Multiple configuration options should appear.
+
+    In the **Project name** field, enter a name for your app that

+    following the [Effective Dart][package-name] guidelines.
