在Flutter中，依赖项必须指定版本号吗？ [英] In Flutter, Dependencies must specify version number?

问题描述

通常，您必须添加以下内容

Typically, you have to add something like

dependencies:
  camera: "^0.2.0"

到pubspec.yaml文件。如果我不包含版本号怎么办？这是一件小事，但通常，我会找到一段代码并想要对其进行测试。在顶部，我看到类似>>

to the pubspec.yaml file. What happens if I don't include the version number? It's a small thing, but usually, I find a piece of code and want to test it. At the top, I see something like >>

import 'package:camera/camera.dart';

我是否必须进入软件包的主页以找到版本号？

Do I have to go to the package's homepage to find the version number?

推荐答案

您可以使用任何

dependencies:
  camera: any

约束使包获取 / 包升级更容易搜索匹配版本，因为它减少了解决方案空间，但是对于简单

Having tighter constraints makes it easier for packages get/packages upgrade to search matching versions because it reduces the solution space, but for simple examples it usually doesn't matter.

pub 最近得到了改进的求解器，使得任何问题都比过去 pub 经常在任何被使用。

pub got an improved solver recently that makes any much less of a problem than it used to be where pub often just timed out when any was used.
