title: What is the difference between the camera and image picker plugins?
body: <p>I’m pretty new in flutter. So bear with me. I’m not sure the difference between plugin “camera” and “image picker”. 
  I was able to capture video and image by using “image picker”. From my perspective,”image picker” is more straightforward and easy to implement but on the internet, seems like “camera” plugin is more popular. 
  Then I want to ask, when it comes to taking video and picture, especially video. Is there any pros and cons? Any help appreciated!</p>
