title: How to convert Android's DP to Flutter's LP? What is the difference between DP and LP?
body: <p>I got the designs for a new app. All the dimensions are Android-ready and are given in DP - (<em>Density-independent Pixels</em>). How can I convert these values to <strong>Flutter's LP</strong> (<em>Logical Pixels</em>). 
  I know that <code>Window.devicePixelRatio</code> gives me the number of device pixels for each logical pixel. </p>
  
  <p>What's the exact difference between DP and LP?
  Are there any built-in methods for dp to lp conversion? </p>
