  1. Thank you, much appreciated!

  2. my 2 hour search is over. At long last, a question mark saved the day!

  3. C# has the same feature since C# 8, why there's no check here? 2:25

    Complier analyzes code flow and warns if some value can be null where is shouldn't be

  4. But it creates problem while declaring global variable.

  5. Super video. Please create more news videos and tutorials.

  6. "Stay null-safe out there", hahaha that's hilarious

  7. thanks a lot got my self clear on it he he he he he he

  8. Thanks for your explanation. What is your native language anyway?

  9. can't you just swift for Flutter 😛

  10. Dart is worst programming language to learn in 2021. It should be inspired by Python. short line of code, easier to understand, easier to learn.
    And Dart is totally opposite.In tech things are getting short and less time consumption but it is worst. It was not expected from Google.

  11. Thank you for such informative and easy to understand guide 😁

  12. avoid using ! , what i do it 90% of time

  13. How to add null safety for this –>
    @Query
    ('SELECT * FROM Favorite WHERE uid=:uid AND id=:id')
    Future<Favorite> getFavInFavByUid(String uid,int id);
    Error –> Query method parameters have to be non-nullable. Define uid as non-nullable.

  14. void main() {
    int? da=null;
    print('hello ${da+1 }');
    }
    I don't understand the exact reason of null safety , above code need to apply null check. then whats the benefit ??

  15. @Filip
    is java has null safety?? I don't think @2:25

  16. Too Many NULLS in a 5 Minute video []~( ̄▽ ̄)~*

  17. Also the larger general programming question is…. Is null a feature or bug?
