BankTransferFlowController class

Headless controller that drives a multi-step money-transfer flow.

UI layers observe this ChangeNotifier and render each step as it changes. The controller stores the user's inputs (amount, beneficiary, isScheduled, scheduledDate) so they can be read back at any point, e.g. to display a review summary.

Network calls are the host app's responsibility. Use markSuccess and markFailure to propagate API results back into the controller.
