  1. Great tutorial. pls make a video on Navigation for web and mobile. e.g web has sidebar navgation on click again and again every route inserted in stack. this is the big problem in flutter for web

  2. New to flutter here. I found something ready-made that I could use in my project, but I was having a hard time replicating it because I didn't understand the concept and the basics behind it. You made it crystal clear, and now I don't have to use the ready-made code; instead I can build it from scratch. Thank you so much. Of course, I subscribed and liked your video.

  3. Spread operator & Null-aware operator on Lists, Maps and Sets in Dart

    Spread operator & Cascade Operator What is the function of each?
    And when do we use each? also witch using with Map witch uing with list?

  4. simple and useful, good job

  5. Love u So Much Brother You Save my Life Always

  6. how can I replace an item in a list with another item in the same index? (ie delete an item and place another item in the same place as it was)

  7. Hello. I am not used to writing in English, but I am writing comments to express my gratitude.
    Many classes deal with List, Map, but like your bike example, lists that require class constructor are often not properly educated with deep explanation, so I didn't understand about that even if I have taken several classes before. But now I understand for sure with your lesson. Thank you!

  8. You are very helpful 👍

  9. can you help me on a project please i have a little problem with lists
    text me please
    yacinserhani@gmail.com

  10. Hi Johannes, if I have duplicated objects in the list e.g. if you have two Hondas in your bikes list, how would you compress or remove the duplicate item?

  11. Thank you, Johan. I really enjoyed this video.

  12. Hello, bro. Do you have videos for testing? If you haven't, can you give me the source, please😊

  13. why is there no automatic translation into Russian (

  14. Thanks for the info! Streightforward and helpful

  15. You are better and more efficient teacher. 🙂

  16. Awesome Content. To the point and useful.

  17. Thanks Johannes for all your videos and their simple explanations.

    Be careful, there is an error in your map explanation:
    This is not the purpose of the .toList() at the end. The reason we generally need it is that .map() produces an Iterable type (MappedIterable) instead of a List type. And generally, widgets accept only List type. So if you want a List type, you have to convert it to a list with .toList(). In this case, because you use it with […iterable], you don't need a .toList()

    So if you only need an Iterable (not specifically a List), you don't have to put .toList(), it will produce a new object anyway. Moreover, this Iterable is lazy, so we can chain several calls without worry about performance.

    See here for the documentation: https://api.dart.dev/stable/2.12.2/dart-core/Iterable/map.html (it always produces a new object)

  18. Thanks, Johannes. Straightforward, comprehensive, and logical.

  19. Great Brother, you are the best teacher I ever had…..

  20. Johannes Milke Rocks…🙏🙏

  21. Man!! Your map explanation was not only the best that I saw but the only one that I understood!!! Finally I know how to use and what is the purpose of .toList() at the end!! thanks God, ops, thanks Johannes!!!!!!!!!!!!! Viva la vida!!!
