and clicked on pub get to get all the dependencies listed in the pubspec. when I went back to my main.dart file to run my app I stumbled upon this error: The IDE suggested creating a `app_localizations.dar' file, but nothing happened! Can someone helps me figure out what is going on and how to solve this error

In the README you can find all the instructions to build from source. The project uses Melos for manging the monorepo, so you first need to install it with dart pub global activate melos and then bootstrap it with melos bootstrap. This command retrieve all the packages and generates the translation code. That's because you got that error about translations.
