My question is pretty much the same as this: Displaying text from a text-file on Firebase storage
Only I want to do it in flutter and I have tried so many things. So basically I created a futurebuilder, future is the getDownloadUrl. Up to this point, it's okay.  
So moving on.
First, I tried nesting another FutureBuilder, where future is an http request to the url. The future does not have any data. I had my shiny little red box all the time, from the else clause of if(snapshot.hasData()){....}else{my redbox}.  
Then I tried a stateful widget where I have the text as loading... and in the then() clause of the get request I called setState with updating the text to the response body. It also doesn't have any data.  
The link is for sure 100% correct, tried it in python, in browser and the best part.... Tried it in a separate dart file. It printed the correct data. Then I imported it in my flutter app, called the function, and nothing happens. I just don't get it. Sorry for the messy question but I'm starting to give up. I like challenges in programming, but only if it has a reason to go bad and i can find that reason.
