Improving translations
Edit the applicable strings_XX.arb file in res/values/ and open a pull request with the changes.
Current list of language files:
- English
- Spanish
- French
- German
- Italian
- Portuguese
- Dutch
- Polish
- Croatian
- Russian
- Ukrainian
- Hindi
- Japanese
- Chinese
- Korean
- Thai
- Arabic
- Turkish
- Burmese
- Urdu
- Bulgarian
- Czech
- Indonesian
- Hausa
- Yoruba
Add a new language
-
Create a new
strings_XX.arbfile inres/values/, replacing XX with the language's ISO 639-1 code. -
Edit the strings in this file, replacing XXX below with the translation for each string.
"welcome": "Welcome to", -> "welcome": "XXX",
- For strings where there is a variable, denoted by a $ symbol and braces, such as ${status}, the string in braces should not be translated. For example, when editing line 106:
"time" : "${minutes}m ${seconds}s"
The only parts to be translated, if needed, are the values m and s after the variables.
-
Add the language to
lib/entities/language_service.dartunder bothsupportedLocalesandlocaleCountryCode. Use the name of the language in the local language and in English in parentheses after forsupportedLocales. Use the ISO 3166-1 alpha-3 code forlocaleCountryCode. You must choose one country, so choose the country with the most native speakers of this language or is otherwise best associated with this language. -
Add a relevant flag to
assets/images/flags/XXXX.png, replacing XXXX with the 3 letters localeCountryCode. The image must be 42x26 pixels with 3 pixels of transparent margin on all 4 sides. You can resize the flag with paint.net to 36x20 pixels, expand the canvas to 42x26 pixels with the flag anchored in the middle, and then manually delete the 3 pixels on each side to make it transparent. Or you can use another program like Photoshop. -
Add the new language code to
tool/utils/translation/translation_constants.dart
Add a new fiat currency
-
Check with Cake Wallet support to see if the desired new fiat currency is available through our fiat API. Not all fiat currencies are.
-
If the currency is associated strongly with a specific issuing country, map the ISO 4217 currency code with the applicable ISO 3166-1 alpha-3 code in
lib/entities/fiat_currency.dart. If the currency is used in a whole region or organization, then map with a reasonable interpretation of this (eg: eur countryCode for EUR symbol). -
Add the raw mapping underneath in
lib/entities/fiat_currency.dartfollowing the same format as the others. -
Add a flag of the issuing country or organization to
assets/images/flags/XXXX.png, replacing XXXX with the ISO 3166-1 alpha-3 code used above (eg:usa.png,eur.png). Do not add this if the flag with the same name already exists. The image must be 42x26 pixels with a 3 pixels of transparent margin on all 4 sides.
