Count Markers on Map

[antykaps]

Hello Community,
I’m trying to count the number of markers created by users on google map
How can I do that
6 markers were stored in the firebase
But with Get Marker Block it shows 22
and Get All Marker IDs it shows 21

Another question
how do you create or define the Marker Id and how do I get it?

Each time you call data from database you should set global variable that gets all coordinates to an empty list and then add values to list and also delete all markets and recreate them

Update Google Map Marker

Hello. I am using Firebase Database to get my Latitude and Longitude and add a marker with that coordinates. But every time the coordinates changes, it does not remove the old marker. here is the blocks. it is in a Firebase Data Change block. [50%20PM]

Thanks Dora

It was simple but I did not think about it

About creating markers
how do you create or define the Marker Id and how do I get it?

I believe they are automatically created, why do you need to define marker’s id ?

I do not need it immediately but on the occasion of the question about the number of markers … Maybe for future use
