title: Flutter-initialize video as quick as possible
body: <p>I'm trying to play videos as user swipe to left or right.<br>
  I was able to play next or previous video by using <code>NotificationListener</code>.<br>
  If user swipe to left, pass next url and initialize,  if swipe right vice versa.<br>
  However with this approach, video will be initialized after user swiped.<br>
  So, it takes a couple of seconds to play.<br>
  How can I make this more efficiently?<br>
  Do I have to initialize next video while current video playing or similar?<br>
  Can someone guide me to the correct way please?<br>
  Thank you in advance!</p>
