Comments on the Vanilla example

A couple of comments.

1. The vanilla sample is too complex for a flutter/dart beginner. The discussion located at flutter_architecture_samples/example/vanilla/ is useful in explaining how flutter can implement inter-widget communications out of the box. However, IMHO it is extraordinarily complex. It has pieces scattered all over the directory structure. Is there a simpler example? Somewhere you wrote that for multiple state values, I might try a Map. Vanilla was the closest example I could find. The example at https://medium.com/@maksimrv/reactive-app-state-in-flutter-73f829bcf6a7 is fine for a single state value but offers no help with multiple values.

2. The following code (from flutter_architecture_samples-master\example\vanilla\lib\models.dart) presumably (from its name) toggles the value of the **complete** member of each TodoEntry

```
void toggleAll() {
final allCompleted = this.allComplete;

todos.forEach((todo) => todo.complete = !allCompleted);
}
```

Why is **allCompleted** invoked? Why doesn't the code read

` todos.forEach((todo) => todo.complete = !todo.complete);`

If that was not what was intended, then the method's name should changed or a /// comment added preceding the declaration.

Kudos: Thank you for your teaching efforts. It is fantastic work!

Start in example/vanilla/, especially example/vanilla/lib/models.dart, and inspect toggleAll alongside allComplete to understand the intended behavior. Review the example’s scattered structure and the request for a simpler multi-value state example. Done means the toggleAll behavior is clearly explained or documented and the beginner guidance addresses the requested complexity.
