There are 3 options:

• Models
• Event Bus
• Parameter in your Navigation

To know which variant fits best for you and really understanding the conzepts I advice you to do follwoing tutorials for models and navigation parameter:

For understanding the event bus following question might help (or at least the answer to it):
