我按照这里的说明(在Linux选项卡下)将Dart安装到Ubuntu Web服务器上.

Dart本身工作正常,但我不能使用Pub命令(只有Dart命令).如何为服务器安装Pub？

我只是想用我 3 个月前存储的相同命令来生成我的文件（我对后端和 devops 不太擅长），现在它不再生成文件了。它告诉我使用我不记得的删除命令，但即使使用该命令，我的文件仍然不会生成。这就是我的日志的样子，您可以在下面找到一个简单类的代码。

我的猜测之一是这与我更改 github 帐户有关，因为提到了权限问题。

我在 Windows 10 中使用 vs 代码。

当我执行flutter pub getor时pub get，这些变化pubspec.lock有时如下所示。

sdks:
-  dart: ">=2.10.2 <=2.11.0-213.1.beta"
+  dart: ">=2.10.2 <2.11.0"

我认为pub get几乎等于 CocoaPods 命令pod install，它不修改锁定文件。
为什么pub get要更新锁定文件？

我已经添加// @dart=2.9到我的所有文件中，但build_runner不会在不抛出此错误的情况下做它的事情：

Warning: Operand of null-aware operation '?.' has type 'SendPort' which excludes null. - 'SendPort' is from 'dart:isolate'.  sendPort?.send(result);  ^Error: Cannot run with sound null safety, because the following dependencies don't support null safety:

在我用 command 更新我的 flutter 之后flutter pub upgrade，这个函数不再被定义，任何解决方案..

我用的是flutter版本2.2.1

文件：Main.dart

这是消息错误

如何解决这个错误？

运行 flutter pub run build_runner build 时出现此错误。

假设我有两个飞镖项目

项目A包含使用Web组件创建一组UI小部件的代码(类似于https://github.com/kevmoo/widget.dart)

项目B包含我的前端代码,它将重用我在项目A中创建的UI小部件.

如果我不想将项目A发布到pub,那么无论如何都要将项目B链接到项目A而无需手动将项目A中的文件复制到B中？

谢谢

使用java/gradle,我可能依赖于mavenCentral和mavenLocal,并将自己的lib发布到mavenLocal.

如何用Dart完成？

即我有多个项目依赖于一些私人库.

正如我所看到的,"pub pub"只能发布到中央回购.
