Summary:

Invalid values are accepted for Date of birth of a customer. The issue persists when the user creates a new customer and when the user edits the details of a customer.

Steps to reproduce:

1. Open the application
2. Tap on View Customer
3. Select a customer
4. Tap on the edit button
5. Tap on the Date of birth field and select an invalid date of birth (e.g 24/05/2030)

Expected behavior:

The field shouldn't accept invalid values for the date of birth of a customer

Observed behavior:

The field currently accepts invalid values for Date of birth of a customer.

Device and Android version:

Device : Xiaomi Mi A1 [tissot] ROM : Stock Android [Oreo 8.0.0]
