什么是申请包？

Question

https://dart.dev/guides/libraries/private-files 本指南提到不要提交 pubspec.lock 文件“应用程序包除外”。应用程序包到底是什么？我如何区分是否应该提交此文件？

Answer 1

你必须避免将不需要的文件、包提交到 git 所以官方 flutter repo 已经给出了你可以使用的 gitignore 文件。将此

.gitignore

文件添加到项目的根目录。

Answer 2

申请包

包含程序或应用程序的包，具有主入口点。意味着可以在命令行或浏览器中直接运行。

应用程序包可能依赖于其他包，但永远不会依赖于它们自己。与常规包不同，它们不适合共享。
