An impressive explanation, everything very clear, thank you very much for your time to create this video.

[@HeyFlutter]

Glad to hear that, You are most welcome Software BJT! 😊

[@devkumar9889]

I came from js and this was so easy to understand
In short : Streams are higher version of Future
Future = Waiting -> Done
Stream = Waiting -> Active -> Done

[@HeyFlutter]

Cool @devkumar9889 😀

Guten Abend Johannes. Ich habe ein Problem. Ich arbeite an einem Projekt, ich muss eine Anwendung oder ein System wie kahoot codieren. Das ist eine Plattform, auf der jeder zur gleichen Zeit Multiple-Choice-Fragen beantworten kann. Aber ich stecke insbesondere bei der Frage fest, wie ich die gleiche Frage allen gleichzeitig anzeigen und ihre Antworten speichern kann. Ich kann zum Beispiel keine Funktion starten, wenn sich eine Variable auf Firebase ändert. Kannst du mir bitte helfen?

Hello Mr. Milke! For the streaming section, I wanted to ask how would you do a broadcast stream? That is, one that you could subscribe to more than once. I've seen other videos that seem to be using older code that use a streamcontroller and set it to be a broadcast. Is that functionality still available? Thank you!

[@ergunerkus]

Hello, thank you for the video, you did not dispose stream, is there any specific reason to not dispose it? or it is unnecessary since you use getUserUpdatedLocationStream() function?

My future builder keeps refetching data. How do I stop this?

[@belveloper]

use snapshot.currentState if it's done ✔️ use a break;

[@josephjoey3904]

@@belveloper share a snippet? I've tried memoizing the function call the api but it keeps firing, every time. I've done what's in the video already with no luck
