Provider: Difference from Singleton

[taliptako]

I wonder if Inherited widget is more performant then using Singleton

[rrousselGit]

More performant than Singleton, no. But they are pretty fast, (O(1) + a constant factor) so the difference is almost non-existent.

But besides performance, there are a couple of strong points that Singletons do not have.

They:

• act as an abstraction.
• are scoped and overridable
• force structured object graph due to the tree nature and unidirectional data-flow of widgets.
• ensure that dependents are always up to date
