[Solved] Need help on checking value on specific location: firebase

HI. Thunker,

I can’t figure out how to check if the specific location contains value/data on firebase prior to save the data.

I can only check if there is a value in user/date/xxx , date folder. but couldn’t figure out how to check the value inside the “IN” or “OUT” folder.

To check the contents of the selected key, you must correctly specify the path to it, which can be copied from the Firebase console after selecting the desired node in it.
