Android Studio makes it really easy for you to rename things that are scattered all over your project.
In our story_brain.dart we want to make the storyNumber into a private property. But storyNumber is used in a lot of places. Without Android Studio, we would have to change it manually in over 10 places. But let's see what we can do using Android Studio's refactoring capabilities.
//TODO: Step 25 - Change the storyNumber property into a private property so that only story_brain.dart has access to it. You can do this by right clicking on the name (storyNumber) and selecting Refactor -> Rename to make the change across all the places where it's used.
Now when you rename the property, the changes will be made to every storyNumber that is used in the project.
