This is a Dart console application that allows a Tourist Agency to book trips for three types of customers:
- Individuals (Requires travel insurance and workplace notification)
- Families (Requires family health insurance and records a family member staying in Canada)
- Groups (Requires organizing hardware and notifies the destination company)
The program follows Object-Oriented Programming (OOP) principles, using polymorphism, encapsulation, and inheritance. It ensures input validation, uses lists for customer storage, and calculates the total price of all trips.
✅ Book trips for individuals, families, and groups
✅ Calculate total price of all trips
✅ Polymorphism: Uses a base class (Customer) and three subclasses
✅ Flow Control: Uses loops, if-else, and switch-case
✅ Input Validation: Ensures correct data entry
✅ List Collection: Stores multiple customer entries
✅ Arrow Function: Used for calculating the total price
