Answer 1

You can create a pubspec.yaml file on root directory or open the bottom terminal and try flutter create. it will provide default structure. Now to get pub package, check the import section and add on pubspec.yaml

Answer 2

If you have a backup then paste the pubspec.yaml file from it. Else take a backup of the project. Run flutter create. in the root directory. It will create the pubspec file in the project. Click on configure dart and add the flutter path then run the project. It will throw errors for the packages used manually enter packages in pubspec or you can try flutter pub add <packagename>
