# getLocalizedLabel method

String getLocalizedLabel(

1. String? language

)

Retrieves the localized label based on the provided language code.

param language The language code for which the label should be localized (e.g., 'en' for English, 'fr' for French). return The localized label corresponding to the provided language code. throws BiosealException An error has occurred during Bioseal Library execution.
