You can follow these steps to support localization when developing new features

Introduction ​

1. You can directly use the text configuration already available in /resource/l10n/en-US.toml to replace the text in the new feature.
2. If there is new text in the new feature, please refer to the configuration text in en-US.toml, pull the new text into the configuration files of other languages such as en-US.toml, and add translations.

Adding a new localized text file ​

1. Add a new language text configuration in /resource/l10n/.
2. Pull existing text configurations from other languages in the new language text configuration.
3. Add translations for the new language text configuration.
