body: <p>what I'm trying to do is to have something like this by building an app in Flutter:
  <a href="https://i.stack.imgur.com/ud8zA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ud8zA.png" alt="enter image description here" /></a></p>
  <p>I Have a list of interest and I want to have this kind of card (autosized based on numbers of character) for each of those, I have no fixed number of columns and each row is filled by the right number of elements based on the number of character and I have all the rows needed in order to print all interest in List.</p>
  <p>Which is the right widget that I have to use?</p>
  <p>I tried with listview but I have only one element for row, I can use multiple columns but this means I have a fixed number of columns.
  I tried also with GridView, but again I have to fix the crossAxisCount (to fix number of columns).</p>
  <p>I have no idea,</p>
