Neoweb4u|That is the second video within the Flutter in Focus sequence on asynchronous coding in Dart. On this episode, study the whole lot about Future objects, Dart’s most elementary …

  1. How's the future status named "uncompleted"?

  2. Ótima explicação, só que diferente disso eu uso o Connection.state que faz os devidos retornos de acordo com o a resposta.

  3. What's the difference between catchError and onError callbacks? both are triggered in case of errors, so why are there two of them?

  4. This channel could potentially make non coders jump in directly as a mobile application devs❤️❤️.
    Uhh sorry cross platform 😁

  5. I am getting "Flutter intent redirection " issue as i upload the app on playstore, and they have given me until 21st December 2020 to clear this issue. if not they'll remove my app

    Please help me

  6. Can anyone tell me what is the datatype of myFuture at 3:27. final means it can't be changed, but what is the datatype of myFuture ??

  7. Loved this video, thank you for explaining things in such a straightforward way.

  8. I think Future API lacks readability.

  9. This is quite similar with promises in ES6, JavaScript.
    And the async/await is quite similar with async/await in ES7, JavaScript.

  10. Is the syntax for the second argument for the delayed method wrong? I can't find it anywhere 5:00

  11. is there a dart equivalent to the javascript "resolve" and "reject" methods passed to a promise handler?
    function getUserInput() {
    return new Promise(resolve => {
    setInputEventHandler(data => {
    resolve(data);
    });
    });
    }
    Because futures in dart seem to just be based on synchronous code that returns a value… but that doesn't really make sense?

  12. I was watching some other Flutter videos and reading code and i saw Future quite a while. At first i thought it was something like Python's _future_ but after closer inspection i realized it's related to asynchronous stuff. Quite good. The concept might seem daunting at first for some people (it sure was my case) but it's actually pretty simple. Some stuff will be done at some point, deal with the result or deal with the error and move on.

  13. Clean and crisp slides and diagram.

  14. Is there a better way to nest FutureBuilders? I need 3 different resources for 3 different widgets on the same screen? Something equivalent of MultiProviders would be really great

  15. I love the gift box analogy …but by any chance can we save it and open at our will?

  16. 2:45 my face when he said gifts contain errors …but it's a gift thou…

  17. Does Future create new thread

  18. can the event loop do more than one stuff at a time

  19. I think catchError and whenComplete are strange. just catch and finally are simple!

  20. Lol. This series is a safe space.

  21. Can ( provider + future ) + widget be used in the same way as set state , with the only difference of rendering that widget instead of whole screen?

  22. After watching this video, I learned that there's an alternative way to pronounce json.

  23. Why not just name them: then, catch, finally?

  24. Thank you
    I read a Json file from storage, converted to map and then update into global configuration

    For me the widget gets updated with old map data while there is a delay in reading file content

    If I put the reading global configuration inside future.then( ), it does not work and gives some exception

    I don't want to use bloc pattern for small data
    Any clue?
    Also shared preferences does not seem to work

  25. future dart is a promise in js world

  26. this thing kinda sucks lol. i'm trying to filter a stream from firestore by userID (i have objects that saved wich user created them)
    been trying for hours, still nothing

    my latest attempt
    child: StreamBuilder( stream: Firestore.instance.collection('properties').where('uid', isEqualTo: getUserId()).snapshots(), ……

    getUserId() async {

    String userId;

    await _authService.getUserId().then((value) => userId = value);

    return userId;

    }

    does not work

  27. What would be the most idiomatic way to synchronize Futures. For example I may have to wait on multiple Futures until I can start processing the data.

  28. Am I the only one who thought the gift example was funny AF?

  29. Thank you! Very helpful and informative!

  30. 感谢字幕制作人员

  31. Can anybody tell me exactly what coding color theme that was?????????????????????????????????????????

  32. Google announced big plans for Dart and was about to replace JS with it but couldn't do it. They dumped it in midway despite being superior than JS. Why they are sticking with Dart now!?

  33. Is this like android handler? Well, handler begins when the app starts and not delayed the first time if its a loop

  34. Make a video on HOW TO MANAGE STATE???

  35. Easy to follow explanation. Why wasn't async/await included? I am unclear after watching this video when/whether to use then vs. await….?

  36. The quality of these videos is astounding. Please keep 'em coming!

  37. The Event Loop described badly, please clarify how it works. If it works like V8 then please add stack call, queue, and tell about external threads for API.

  38. Where is Emily Fortuna??? 🙁

  39. And scopes and closures work like in javascript?

    String url = 'https://';
    http.get(url).then((resp) {print(resp); print(url)} )
