在Android Studio中创建包含示例的Flutter包
1.创建新的Flutter项目x1c 0d1x
1.选择Flutter包

1.在Android Studio中打开新项目后，选择“终端”选项卡，然后运行：

** Flutter 创建示例**

1.选择“编辑配置”-〉添加配置-〉选择位于示例/lib文件夹

x 1c 4d 1xx 1c 5d 1xx 1c 6d 1x中的主.dart文件
1.打开示例pubspec.yaml，并通过添加以下内容链接到库：
您的软件包名称：路径：..

注意：当你打开Example文件夹时，它看起来就像一个嵌套在你项目中的完整Flutter应用程序;那是因为它就是这样，只要打开io和android文件夹，就能看到它们都有这样的模式：

在项目的根目录中创建一个名为example的新项目，然后删除不必要的文件，如CHANGELOG、LICENSE和README，因为它们将位于包文件夹中。
下面是我创建的一个包的示例（没有双关语）：
第一节第一节第一节第一节第一次
现在在pubspec.yaml中，你应该像这样把你的软件包作为dev依赖项包括进来：

dev_dependencies:
  your_package:
    path: ../

我相信您也可以使用常规依赖项，但这对我很有效。
现在，在/lib中，您可以添加一个main.dart文件，导入您的包，然后创建一个示例项目。

转到项目根文件夹并运行flutter create example。
就是这样。

使用项目根目录中的内置flutter命令行工具来完成所有工作：

/e/projects/myproject # flutter create example

其具有以下输出：

All done!
[√] Flutter: is fully installed. (Channel stable, v1.12.13+hotfix.5, on Microsoft Windows [Version 6.1.7601], locale en-US)
[√] Android toolchain - develop for Android devices: is fully installed. (Android SDK version 29.0.2)
[√] Android Studio: is fully installed. (version 3.5)

In order to run your application, type:

  $ cd example
  $ flutter run

Your application code is in example\lib\main.dart.

如果使用Android Studio 3.5.2，请运行默认示例以确保安全：
1.从工具栏的Flutter下拉菜单中选择 *Edit Configurations... *，为示例main.dart添加新配置。
1.选择 Run/Debug Configurations（运行/调试配置） 对话框左侧的Flutter目录并按下 + 按钮。
1.选择 * Flutter *
1.单击 Dart entrypoint： 对话框中的文件夹，在新的example/lib目录中浏览main.dart。
1.单击工具栏上的三角形运行按钮。
我只是为我自己的项目执行了这些步骤，它工作得很完美。
然后，要为您的项目进行定制，请编辑示例的pubspec.yaml文件，并向您的项目添加依赖项：

dependencies:
  my_project:
    path: ../

• 在我的例子中，我忘记添加示例文件。我是这样添加的。* 你可以在我的pub.devlocation_provider包中检查。

1)在包内创建目录/包。包/目录的名称必须为“example"。有关详细信息，请查看此选项。***
2)打开命令终端并使用以下命令移动到***示例***包内

cd example

3)使用命令在其中创建Flutter项目

Flutter create

4)您将在其中看到***lib/main.dart***文件。请在此文件中添加您的示例。
5)添加后，将最新代码推送到github。
6)在***pubspec.yaml***文件和***CHELLAGELOG.md***文件中增加软件包的版本。然后，运行这些命令将软件包发布到*pub.dev。

Flutter publish --dry-run
Flutter publish

• 之后，您将看到**pub.dev*中的示例选项卡
