How do you navigate between screens (routes)?

Updated Apr 28, 2026

Short answer

By using the Navigator class, which manages a stack of Route objects using push and pop methods.

Deep explanation

In basic navigation (Navigator 1.0), you use Navigator.push() to add a new screen to the stack, and Navigator.pop() to remove it and go back. Screens in Flutter are called Routes, typically wrapped in MaterialPageRoute to provide platform-specific transition animations.

Real-world example

Clicking a product card in a list to navigate to the product detail screen, and then tapping the back button to return.

Common mistakes

  • Pushing the same screen multiple times onto the stack instead of replacing it, causing deep, memory-heavy route stacks.
