Use case

When creating a new project from the skeleton template flutter create -t skeleton project_name . It works as intended but it uses AnimatedBuilder to listen to the ChangeNotifier, recently ListenableBuilder has come to stable, which provides the same functionality that AnimatedBuilder but, and I quote "has a more friendly name for the class and for the parameter that it listens to, intended to make it more discoverable and less confusing for new users." as per #116543 .

Proposal

Update the template to use ListenableBuilder instad of AnimatedBuilder. Tests should remain the same without the need for new ones as the functionality will be identical after the change.
