💡 Hint

Common Mistakes

Using pop instead of push removes the current screen instead of adding a new one.

Using remove or replace are not standard Navigator methods for adding screens.

The push method adds a new screen on top of the current one, showing the new screen.

💡 Hint

Common Mistakes

Using push adds a new screen instead of going back.

Using pushReplacement replaces the current screen but does not go back.

The pop method removes the current screen and returns to the previous one.

💡 Hint

Common Mistakes

Using push adds a new screen without removing the old one.

Using pop removes the current screen but does not add a new one.

pushReplacement replaces the current screen with a new one, which is useful to avoid stacking screens.

4fill in blank

hard

Fill both blanks to navigate back until a specific screen is reached.

Flutter

Navigator.of(context).[1]((route) => route.[2].name == '/home');

Drag options to blanks, or click blank then click option'

ApopUntil

BisFirst

Csettings

DisCurrent

Attempts:

3 left

💡 Hint

Common Mistakes

Using pop removes only one screen.

Using isFirst or isCurrent are boolean checks, not properties.

popUntil pops screens until the condition is met. The settings property holds route info like the name.

5fill in blank

hard

Fill all three blanks to create a named route navigation with arguments.

Flutter

Navigator.of(context).[1]('[2]', arguments: [3]);

Drag options to blanks, or click blank then click option'

ApushNamed

B/details

C{'id': 42}

Dpop

Attempts:

3 left

💡 Hint

Common Mistakes

Using pop instead of pushNamed does not navigate forward.

Passing arguments incorrectly causes runtime errors.

pushNamed navigates using a route name. The route name is /details. Arguments can be passed as a map like {'id': 42}.
