In this step, I will create the StreamBuilder.js inside the utils directory to handle the counter request from the UI. Moreover, developers can handle errors and implement customer handlers within this.

In the AsyncSnapshot class, we can initialize a constructor, handle our data (check availability, etc. ), and handle errors. But in this example, I have only returned the data for ease of demonstration.

The initial data is passed into AysncSnapshot class and stored in the snapshot state for each subscription. Then it will get rendered in the UI components.
