最近 room 的 Migration 是新增一個 table

@Entity
@TypeConverters(RolesConverter::class)
data class BikePositionRoom(
    @PrimaryKey
    val id: String = UUID.randomUUID().toString(),
    var city: String,
    var positionName: String,
    var latLng: LatLng,
    var available: Int? = null,
    var total: Int? = null
)
