title: How logical pixels translate to physical pixels
body: <p>First question:</p>
  
  <p>If I create a Container widget with width set to 50 (logical pixels), how many physical pixels will this widget occupy eventually?<br>
  It is correct to assume the answer will be 50*devicePixelRatio and it will be rounded off to an integer value?</p>
  
  <p>Second question:</p>
  
  <p>This question technically arises from the first question. Let say we have 2 devices and each has the same screen width , same resolution but different screen height. In theory, the width value in logical pixels should be the same for both devices right. 
  However, one devicePixelRatio will be higher. Hence, the eventual width value in physical pixels will be different and this might cause one of the Container to overflow since my assumption is that the eventual Container widget width will be multiplied by the devicePixelRatio.</p>
