Neoweb4u|Do you know that widgets can dispatch notifications? As an example, Scrollable widgets like ListView dispatch scroll notifications. Use NotificationListener to …

  1. Lol just knew after 2 friggin years. Nice

  2. So….

    1. "Notification"s are bubbled up to "NotificationListener" parent widget. Seems fairly good for event driven process.

    2. Changes of "ValueNotifier" are go down to "ValueListenable + ValueListenableBuilder" descendent widgets.
    Right? What about just to use "InheritedModel"? Or sort of state management libs.. It seems like a very low level widget.

  3. The Intro Music sounds retro now.

  4. Background music is super

  5. Excellent beginning music and ending music

  6. so….. redux for flutter

  7. With this, I can finally buy myself a good mattress. Thank you.

  8. This is a really crisp overview, thank you!

  9. mh. this seems like a very easy way to do state management.

  10. it sounds like a good way to ruin the smoothness of scrollable widgets, even with a single listener along the tree

  11. What's a real use for the notification listener?

  12. Plot Twist : It's not about actual notifications we say in Android development. It's called event listeners. E.g. Scroll event

  13. This is seriously awesome 😍

  14. Woahh! Very neat 👍🏻

  15. Chinese translation is some bad.

  16. Another widget very useful, thanks!

  17. I love this series! Great video as always 🙂

  18. People who type something like "I love Flutter" or "Flutter is awesome" under literally each Flutter video, are you bots or real?

  19. thanks Youtube for the notification of the widget notification

  20. I've a question regarding this widget if any dev from flutter team can answer it.

    Is there any way to find source of Notification. Like I have 4 scrollable widgets & I want to listen 2 of them. I tried adding keys in they but I got something else in notifcation context.

  21. Is it not provider package?

  22. The team who designed flutter and dart are just so brilliant.
    I have no words to explain how happy I feel with this stack.

  23. I thought it was Notification listener service from Android for a sec there…

  24. This should become something like jquery listeners that can listen to $(document).on() events. Wrapping a tree in a single listener which accepts multiple events would be useful. As far as I understand you now have to define a new listener for every type of event you're expecting. which can result in messy trees imo.

  25. I wish everything wasn't a widget. The code becomes extremely noisy and indented. It doesn't even help to break everything up into super small parts.

  26. yeessssssss, finally, i love flutter team I Love it

  27. This is my favorite section!
