title: MutableList<DualCamera> Possible to construct without argument or mistake by google?
body: <pre><code>data class DualCamera(val logicalId: String, val physicalId1: String, val physicalId2: String)
  
  fun findDualCameras(manager: CameraManager, facing: Int? = null): List&lt;DualCamera&gt; {
    val dualCameras = MutableList&lt;DualCamera&gt;()
  
    // Iterate over all the available camera characteristics
    manager.cameraIdList.map ...
  </code></pre>
  <p>Google provides this code as an example. You can find it through the link below. Unfortunately my IDE tells me that a value parameter 'size' is missing from the constructor of <code>MutableList&lt;DualCamera&gt;</code>. Did Google made here a mistake or did i miss something? And how to fix it? I want to use this code.</p>
