title: Flutter - How can I add a Google Map but inside a Card/Container Widget?
body: <p>I have read a whole lot about this topic on Google and forums but I can't really understand how to use the Google Maps API.</p>
  
  <p>[TL;DR]
  I want to create a Google Maps Widget that fits inside a Card so when the user taps the Card it gets bigger and easier to use.
  [TL;DR]</p>
  
  <p>I'm new into Flutter and I don't really know how to use certain Widgets. I'd be happy if anyone just helps me solving this, but I'd also like to understand how to create certain Widget for calling it later in the main class of the app.</p>
  
  <p>Thanks!</p>
