dart - pubspec.lock和pubspec.yaml之间的区别

Question

pubspec.yaml和pubspec.lock有什么区别？两者都持有依赖版本。

Answer 1

The first time you get a new dependency for your package, pub downloads the latest version of it that’s compatible with your other dependencies. It then locks your package to always use that version by creating a lockfile. This is a file named pubspec.lock that pub creates and stores next to your pubspec. It lists the specific versions of each dependency (immediate and transitive) that your package uses.

在 pubspec.yaml中，只有包和版本需要使用。在pubspec.lock中，还有您需要的软件包和版本，以及您使用的每个软件包。
