i18n and l10n

[joeblew99]

It woudl be good if your also had an example of i18n and l10n.
This is a hard area for devs to get used to.

There are also flutter plugins that allow the i18n to be exported to CSV, so many translators can work on them and then reimport back into the Flutter and gen the ARB, etc
here is the one i use: https://github.com/aloisdeniel/flutter_csv_localization

• it wil get pluralisation soon :)
