I download everything from the url and overwrite the .arb files with the data from the url. I want AppLocalization to be rebuilt for each language with new texts. I tried to create this function using intl , intl_translation and arbify but saw neither generateFromArb or GenerateLocalization

I tried to use intl , intl_translation and arbify but it didn't work or I had to downgrade other plugins, maybe I used them wrong?
