I want my app to be usable in both UK English and American English. As you know they have different spellings of the same words like "Colour" vs "Color" and using "z" instead of "s".
In native mobile development (i.e. swift, objective C, kotlin, java) this is achieved by having a Strings file that contains all the strings you intend to translate in the app. This also has the effect of having all the strings in one place so when someone wants to change the copy it's extremely easy to do.
I see in FlutterFlow the localization in the Settings, but it only does one English.
How can I get Flutter Flow to present the correct spellings in UK and American?
Also, is there a central place where I can put all the strings so it's easy to change and I don't have to go manually hunting for every place where a specific string was used? e.g. the design has "OK" in a button title in 20 screens but now the client has decided it should say "Confirm" (real life would have a more complicated use case, this is just a simple example at the top of my head).
