Firebase/Firestore Change Kotlin Pojo Property Name Mapping (SerializeName)

We might have property/field sequenceNumber and we want to save it as sequence_number in Firestore.

Use @PropertyName annotations on the getter and setter generated by Kotlin.

NOTE: Read about Kotlin Annotation Use-site Targets

class Test (    @get:PropertyName("sequence_number")    @set:PropertyName("sequence_number")    var sequenceNumber: Int = 0)

or

Use @JvmField (not to generate setter/getter for this property) with @PropertyName.

class Test (    @JvmField @PropertyName("sequence_number")    var sequenceNumber: Int = 0)

NOTE: I have filed an issue to Google to check if this is the intended behaviour and syntax. Tested with com.google.firebase:firebase-firestore:18.0.1.

class Test (    @PropertyName("sequence_number")    var sequenceNumber: Int = 0)

NOTE: @PropertyName doesn't work here, as sequenceNumber is saved in Firestore instead of sequence_number

class Test (    @get:PropertyName("sequence_number")    var sequenceNumber: Int = 0)

NOTE: @get:PropertyName is insufficient, where save is succesful but retrieval of the saved value will fail.
