title: How to make Flutter Markers in Firestone CRUD?
body: <p>I am developing a function inside of a flutter app.</p>
  <p>Its will work like this:</p>
  <p>pressing a button adds a custom marker.</p>
  <p>That is, a new page opens and you can complete: -Name -Description -Raiting -Google Map with current location, but allowing to move the marker to another side.</p>
  <p>The problem is the following, I need to have a guide on how to implement it, since I have not found much information about it.</p>
  <p>From what I understand, I should do a CRUD operations with FIRESTORE. I know how to store and modify the data of the TextFields of name - description - etc etc.</p>
  <p>But I do not know how to implement the map view with marker not added automatically in the general map, when saving.</p>
  <p>I will leave an example of how the marker is added to the screen.</p>
  <p>It should be noted, that when the users enters, they will see a general map from Google Maps with their location and on one side of the screen there must be a button to add a marker.</p>
