I'm trying to read this data

[Pratamatanar]

how do i read all values ​​from this data:

{
"alarm": {
"-NQF0Wy4BqMRi-8Twr8y": "14:16",
"-NQF0i1yEN3g3mqLCUOO": "02:16",
"-NQF0kbTvQcDEqFQbz6X": "02:16",
"-NQF0nSiEXBn9weXgnKR": "19:09",
"-NQP5ONwpNvqrKmXVyE8": "15:13"
}}
using the for loop technique

You can see how to iterate through the JSON data from this function that prints all types of data from FirebaseData objects which was used in all RTDB examples.
