Using setState() and InheritedWidget 's gave us the ability to control how our application re-draws itself based on state changes in real time. In part 2, we will introduce the Provider package, adding another tool in our toolbox for managing state. Provider gives us "syntactic sugar" on top of the InheritedWidget and gives us an easy to use API that help us to remove the amount of boiler plate code that we have to write which is always a win. Referencing the Provider package in your Flutter application When building Flutter apps we make use of the Dart package management system pub.dev . Pub is very similar to other package managers from other languages. In order to install the Provider package into our project we will need to run the following command...

When programming declaratively we describe what needs to be done and our system responds based on the action we describe. What does this mean for Flutter?  In Flutter we describe what should be done in our app and Flutter responds by drawing our...
