Understanding Parameter Passing in UI-Router with ui-sref

In UI-Router, passing parameters to a state when transitioning via ui-sref requires specific configuration. Let's delve into the steps:

1. Define URL Parameters:

Define the expected URL parameters in the state's url property. The syntax is :paramName? where paramName is the parameter you want to receive. For example:
