Pricing for Firestore when using StreamBuilder

Issue

When using StreamBuilder in Flutter to read changes in a document in Firestore, how am I charged?

Am I charged for each time I listen whether there is any change or not multiplied by number of users or any different pricing is used.

Solution

After doing some research and reading documentation, I am ready to answer my own question.

If we are using StreamBuilder to fetch Snapshot from Firestore then we are charged for read only when the data is updated and are NOT charged continuously.

Hope it helps someone else.
