What is the difference between Navigator.push, Navigator.pushReplacement, and Navigator.pushAndRemoveUntil, and when would you genuinely reach for each individual one of these three particular methods?

Navigator.push simply adds a new screen on top of the existing stack while properly keeping every previous screen still genuinely available to return to, Navigator.pushReplacement replaces the current genuinely topmost screen with a brand new one, meaning the user genuinely cannot navigate back to that particular replaced screen, useful for a scenario like a splash screen transitioning to a home screen, and Navigator.pushAndRemoveUntil pushes a genuinely new screen while also properly removing several other previous screens from the stack based on a specific given condition, commonly used after a genuine successful login to properly clear an entire previous authentication flow.

Navigator.pushAndRemoveUntil(
  context,
  MaterialPageRoute(builder: (context) => HomeScreen()),
  (route) => false,
);
