Builder (Flutter Widget of the Week)

Most of the time, widgets in Flutter build without looking up any extra information about their parents. Sometimes, you might write some code where the child widget needs to access the build context of a parent widget in the same build method. That's what the Builder widget is for!

This video is also subtitled in Chinese, Indonesian, Italian, Japanese, Korean, Portuguese, and Spanish.

I love how these widget of the weeks are getting more and more likes. Shows how much people are loving flutter once they get into the eco system.

Why didn't I come across this widget a couple of weeks ago when I needed a Scaffold of context. I split my widget into 2 separate ones but Builder would really simplify my solution

[PetarVukmanovic]

I think widget of the week should have been among the first videos published. 😂 Some of learned this the hard way. 🤗

Awesome! Although i knew and used it, but just followed a pattern and donot why, and never thought the reason doing that .
This is absolutely reveal the truth of my world!!

Builder widget function should be implemented on regular scaffold widget, so we don't need to add this in the future.

[ciprian]

Just used this one day ago! Excellent!

[Jobic-]

Simple, precise and short. Amazing as always.

Why do you need the builder widget, why scaffold.of(context) doesn't work? Why splitting it in a custom widget works? Isn't context a parameter to pass data from parent to child ?

Hi please, can you make a video about ValueNotifier and Stream using in practice? They are very similar in practise. I know that Value Notifier can be used for animation but difference in logic is little understandable

[berkankucuklu]

So I need only one build widget per .dart file, am I right?

[jakubblaha]

I really like these videos. Keep doing that please.

[broooth]

Just like a few days ago I was looking for this but ended up moving the code (that needs context) to a separate widget.

[carrotping]

I am confused. The widget Builder solve the problem widget cannot directly get its own context before parents complete its build function? But why split to the stand-alone widget can solve this problem.

This the important in the flutter, i like it

Please create the same videos in spanish! If you have channel for the spanish speaker community and share the same video but in spanish would be great. The community that speak spanish is huge and the people are really interesting to learn flutter.
