#8 - BuildContext In-Depth Explanation - Fix BlocProvider.of() fails to find a context containing...
HTML-код
- Опубликовано: 16 ноя 2020
- Hi there!
Here's the github repository where you can clone all the source code:
github.com/TheWCKD/blocFromZe...
In this tutorial I will introduce you to how Flutter builds the widget tree and how the widget tree is structured and organised by using build contexts. Build contexts are a really, really, really important feature of Flutter and I can bet most of you don't understand it 100% accurate. So today I will talk about how you can manually build the widget tree by yourself, along with all the widgets and their specific build contexts. I'll also show you how BlocProvider.of(context) works in order to lookup for a BlocProvider widget inside the widget tree. We'll see, understand and fix the well-known BlocProvider.of() fails to find a context containing a specific bloc/cubit error, and many many more!

The best explanation about BuildContext I've seen so far! Congratulations!
You're welcome! I am glad I helped!
This playlist is such a gem..
Even though the code in some videos is a little outdated, the concepts are very well explained, and I always find myself coming back for a revise.
Watched several BuildContext explanation videos on RUclips, and most of them were just scratching the surface, and merely advising how devs can work around the gotchas without providing under-the-hood understanding of it.
Thanks, appreciate how detailed you went over this!
Glad I could help, man! ✨ 🥂
Love your work! This crucial topic is overlooked by all flutter tutorials I've seen so far.
Man, many thanks. You've made my development fun - I can now say I'm familiar with Bloc and I not fighting anymore with my code.
You're welcome, man! I really appreciate that my videos helped you become a better developer!
Same
This is the best explanation of how to build context works with Bloc that I have seen so far. Excellent work done. I hope you receive much more support in future for this.
This was awesome! Thank you so much. Love this entire series and especially all the hard work it took to painstakingly create the animations.
I have watched terribly many explanations not only about buildcontext but many other things, I can surely say that this channel is the best one on youtube. Love it, keep it up man
this is priceless, thanks so much. I was having a context nightmare with BloC after migrating from riverpod and was trying to avoid a side project because of it. Youve put me back on track. Great video series, thanks very much.
No way man! I had a really hard time understanding this concept, but this explanation is unique and easy to comprehend. Thank you
Thank you so much! ✨
Best flutter tutorials I’ve ever seen. Thanks for explaining the details in such a clear and concise manner
Thank you so much for this detailed, positive feedback! I really appreciate it!
i just fixed my crashing app just after this 23:18 minutes tutorial on context. Thanks you WCKD, Stay motivated and keep posting such rich content
This Tutorial series is first where i understood bloc very well Thanks
Thank you for everything. I was struggling about learning BLoc but I understand most of the logic behind the scenes now. Best explanation :)
thanks for this playlist about bloc, it make me easier to learn it, keep it up man.... I will wait for another tutorial playlist from you
It was a the best explanation of BuildContext. Now I have clarity in mind about buildContext.
The tutorial is not only to learn about Bloc concepts but also to learn about BuildContext in Flutter core concepts. Thank you very much :3
Thanks, WCKD. Must watch and needed one!!! I personally addict to bloc and your videos as well.
Keep rocking!!!
Nice to hear that, mate! 🌟 Thanks a ton!
Hi, I just wanna say that I really appreciate what you're doing here. I've binge watched all your previous videos up to here and have made sure to like all of them atleast as a show of gratitude :D
I really like the way you explain and visualize the concepts that's very easy to understand and follow through. I was actually researching about this topic for a while and stopped since I cannot grasp it properly then. Watching your videos made me confident about it now and in turn made me feel positive and happy.
I was actually really excited when I was talking about your videos to someone and even said that the ability for it to teach is very good and could actually be a worth-it paid course, if ever.
Keep up the great work! You've really improved a lot.
Thank you so much for your kind words, man! I really appreciate the positive feedback you gave me! I'll struggle to give you and my viewers the best tutorials! I'm glad you think I have improved over time! Thanks a lot again and hope I'll see you soon in the comments section of newer vids!
You deserve it! I was actually a little sad that I've seen everything up to this point that I have nothing else until your next one - in a good way that is. It's like a good TV show that you just wanna see the next one as soon as possible. :D
I'm looking forward to them. Keep safe also!
Thank you so much! ✨ I prefer quality over quantity so that's why it's taking so much time to post tutorials
What a fantastic explanation of BuildContext. Thank you so much for sharing.
For a long time. I am working on dart language. And at the same time, I produce products, trainings and content in my own country. I would like to say as a member of the Google Developer Community. Your content helped a lot with the projects I developed. Appreciation of the quality of the contents and the work in the preparation process. Keep going like this.
Thank you so much, I really appreciate your feedback! ✨
