A guide to Inherited Widgets - Flutter Widgets 101 Ep. 3

In the previous episodes, we have covered stateless widget and stateful widget. In this video Filip Hracek will be introducing inherited widgets, what it is for, how to use it, and some sample cases.

I want this level of calmness in my life.

Just for those who need that little bit of extra information:
You create the subclass of the InheritedWidget (as explained in the video) and that subclass has a constructor that takes a widget as a child. The idea is to (in the build method of your app) wrap your top widget in there and put your Inheritedwidget on the top. That way the InheritedWidget is very much on the top and accessible by everyone. (I know it is obvious...once you figure it out). Hope this saves someone some time ;)

I liked the part of service so much, so inspiring with these sounds in background.

Fantastic video! I can't imagine how many takes that must have required.

[CodeXdev]

"Interview question". I remember it was one of them. Nicely explained!

[jagdishshetty]

Great short videos from the flutter team !!! Keep them coming !!!

[danilyusupov]

Nice guy! Thanks for explanation, was really helpful 👍

[KuroManX]

After a year of studying flutter I finally understood this concept.

[heshansandeepa]

Very nice, this guy is like a Temple. Focused, calm ( not so enthusiastic voice ). I like it :D

[nonybrighto]

Lol... Good one ! The video is both funny and educational. The sound effect made me laugh 4:06 made me laugh

[tinatahmasebi]

Wow! Perfect. Creative and fun example. It always will be kept on my mind. :D

for those who will look this video in 2020 - method is deprecated, use context.dependOnInheritedWidgetOfExactType<InheritedNose>(),
ok, google, are you going to update videos about your framework :) ?

[bukunmialuko]

Nice. If this man has a youtube channel, im subscribing.

There's a mistake in the video at 2:35 - the nose object was supposed to be assigned from the asset member of inheritedNose - so the code should read final nose =

Haha! I like the nose example very much XD Finally I can understand InheritedWidget by this video, thanks!

When you want to grow up your size of project, you must be annoying of a a lot of different widget dependency. What a good flutter team! has provided a bloc pattern support inside of flutter. You don't need to npm / yarn install something and write a lot of coding (compare with redux). I think bloc pattern is the best solution for handling dependency between widget.

At 1:53, I am having error in the line final nose = ... at the word asset.

However using it seems to work.

Edit: I had to use
as InheritedNose).asset

[alexandreaugustolg]

Thank's God, now I got it! Thank's for the explanation!

[RahimSekkouti]

Very informative video! Thanks Flutter Team 🙏
A quick question, in order to get the asset variable in the build() method:

final nose = InheritedNose.of(context);

shouldn't the asset be returned from the of() method such as:

static InheritedNode of(BuildContext context) =>

I think some of the syntax is now outdated; correct me if I'm wrong.
(I'm using Flutter 2.0.3)
