ChangeNotifierProvider example

[stocksp]

Is the example code show by @brianegan in "Merge provider and scoped_model"
brianegan/scoped_model#61 the "correct" way to use this provider?

Simple examples of the existing providers would help a lot for users of "scoped_model". Your only example of the 'simple' provider seems to me to be the least useful as it isn't 'reactive' (if I'm reading the docs correctly)

thanks for all your work!

All providers are reactive. ChangeNotifierProvider is built on the top of the one in the example.

Improving the documentation and making great examples is definitely needed. But note that, as opposed to scoped_model, there's not a single possible architecture using provider.

provider is a mean, not the end.

"This is perfect for exposing a complex object that never changes over time without writing a StatefulWidget"
never change .. is where I got the 'non reactive' thought.
In Scoped_model we extend out model from the included Model class and call 'notifyListeners' to get reactivity. Which is the source of my confusion.

never changes over time

That's for the default constructor.
Provider.value constructor properly updates dependents when the value changes.

The mean to achieve the update is different though. Instead of a Listenable/ChangeNotifer, you'll need a stateful widget and call setState to update the passed value.

Ahhh ...

thanks, got it now!
