问题 Just started using doxygen today. How would you go about this. Given following dir structure -rootDir -dirA -dirAFile_ver01 -dirAFile_ver02 -dirAFile_ver03 -dirAFile_ver04 -dirB -dirBFile_ver01 -dirBFile_ver02 -dirBFile_ver03 -dirC -dirCFile_ver01 -dirCFile_ver02 My expectations from doxygen are to take only last version of file from single dir e.g. dirAFile_ver04 from dirA , dirBFile_ver03 from dirB etc. I've read about FILE_VERSION_FILTER tag, but I'm not able to make it work.

And is it possible to do this the other way

问题 TLDR: How to force a specific Flutter package (library) version for the entire app? Let's suppose I have the following dependencies in my pubspec.yaml file: dependencies: flutter: sdk: flutter datetime_picker_formfield: 0.4.3 date_utils: 0.1.0+3 intl: 0.15.8 which gives me a version conflict error: Because flutter_app depends on date_utils 0.1.0+3 which depends on intl ^0.16.0, intl ^0.16.0 is required. but when we change intl to intl: 0.15.8 we get: Because flutter_app depends on datetime
