In this lesson, you’ll explore filtering operators in Kotlin Flow. These operators let you refine the data
flowing through your streams by excluding items that don’t meet specific criteria. You’ll cover the following operators:
filter: This operator allows you to keep only those items that meet a certain condition. It’s like a sieve that lets
you pick and choose which elements to keep in the flow.
drop: This operator allows you to skip a specified number of items from the flow. It’s useful when you want to
ignore initial items or data that isn’t relevant to your processing.
The filter Operator
You’ll begin with the filter operator. Suppose you’re processing a flow of carrots and only want to keep those that are
fresh. You can use filter to create a flow with just the fresh carrots:

enfmohun eq jzi gnif. Exneqpigo, ap’d upkkolav.
The drop Operator
Next, consider the drop operator. Imagine you have a flow of carrots, but you always throw the first one because you heard doing that gives you good luck!

Wrap-Up
In this lesson, you’ve explored key filtering operators in Kotlin Flow, including filter and drop. You’ve seen
how to use these operators to refine and selectively include items in your flow, letting you focus on the relevant data.
