{camelCase} parameter gets automagically translated

[fgarciaDev]

Default string value, in 'en-US.json', has a camelcase param in the string and it ends up being translated, but ONLY for 'es' language. I have added 'fr' and 'ru' langs as well, but those strings are translated and keep the parameter name as intended. I mention the camelcase because I have params without camelcase and they are all correctly translated.

Default en-US ==         "hoursParked" : "{hoursParked} hours parked",
Translated es-MX.json => "hoursParked": "{horas estacionadas} horas estacionadas",
Translated fr-CA.json => "hoursParked": "{hoursParked} heures de stationnement",
Translated ru-RU.json => "hoursParked": "{hoursParked} на стоянке",

Does it happen in the dart code generation, or in the json files by the google translate api?
