Flutter Navigator RouteTransitionRecord

The RouteTransitionRecord class in Flutter is an abstract class that acts as a wrapper for a Route object, primarily used in conjunction with TransitionDelegate to manage and control how routes transition onto or off the screen in a Navigator.

Core Properties and Functions

• route: This getter retrieves the underlying Route object that is wrapped by the RouteTransitionRecord.

• isWaitingForEnteringDecision:

  • This boolean property indicates whether the route is awaiting a decision on how it should transition onto the screen.
  • If true, it means that an explicit decision is required, usually made in the TransitionDelegate.resolve method.

• isWaitingForExitingDecision:

  • Similar to isWaitingForEnteringDecision, this property indicates whether the route is waiting for a decision on how it should transition off the screen.

Transition Decision Methods

• markForPush():

  • This method is used to mark the route for a push operation with an animated transition.
  • It should be called during the TransitionDelegate.resolve process for entering routes that are waiting for a decision.

• markForAdd():

  • This method marks the route to be added to the Navigator without an animated transition.
  • It's used for entering routes during the TransitionDelegate.resolve process.

• markForPop(result):

  • Used for exiting routes, this method marks the route to be popped off the Navigator with an animated transition.
  • An optional result can be passed.

• markForComplete(result):

  • This method is for exiting routes to indicate that they should be completed with the provided result and removed from the Navigator without an animated transition.

• markForRemove():

  • This is used to mark an exiting route to be removed from the Navigator without completing and without an animated transition.
