Summary  
This chapter demonstrates how to implement code for custom page transitions by using a route builder’s pageBuilder and transitionsBuilder to drive animation effects like fade, scale, and rotate instead of relying on platform defaults.

General domain of usage  
Mobile app navigation

Custom page transitions in Flutter let you define how one screen animates to another instead of using the platform’s default navigation animations.

Definition

By default, Flutter uses platform-specific transitions, like slide-from-right on Android and Cupertino-style slides on iOS. Creating custom transitions allows you to fade, scale, rotate, or combine effects to better match your app’s branding and improve the overall user experience.

This example uses `PageRouteBuilder` to create a custom fade transition. The `pageBuilder` defines the target screen, and `transitionsBuilder` uses the animation value from 0.0 to 1.0 to drive a `FadeTransition`, making the new page fade in instead of sliding.
