Flutter脚本执行插件flutter_scripts的使用

当然，以下是一个关于如何在Flutter项目中使用flutter_scripts插件来执行自定义脚本的示例。flutter_scripts是一个Flutter插件，允许你在pubspec.yaml文件中定义和执行自定义的Dart脚本。

1. 添加flutter_scripts依赖

首先，你需要在你的pubspec.yaml文件中添加flutter_scripts依赖：

dependencies:
  flutter:
    sdk: flutter
  flutter_scripts: ^x.y.z  # 请替换为最新版本号

然后运行flutter pub get来安装依赖。

2. 定义自定义脚本

在你的Flutter项目根目录下创建一个名为tools的文件夹，并在其中创建一个Dart脚本文件，例如custom_script.dart。这个文件将包含你想要执行的自定义逻辑。

// tools/custom_script.dart

void main() {
  print('Hello from custom script!');
  // 在这里添加你的自定义逻辑
}

3. 配置flutter_scripts

在你的pubspec.yaml文件中，添加flutter_scripts配置部分来定义你的自定义脚本：

flutter:
  # 其他配置...

flutter_scripts:
  custom:
    script: tools/custom_script.dart

4. 执行自定义脚本

现在，你可以通过运行以下命令来执行你的自定义脚本：

flutter pub run flutter_scripts:custom

运行该命令后，你应该会在终端中看到输出：

Hello from custom script!

完整示例

以下是一个完整的示例，包括pubspec.yaml和custom_script.dart的内容：

pubspec.yaml

name: my_flutter_app
description: A new Flutter application.

# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.3
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
version: 1.0.0+1

environment:
  sdk: ">=2.12.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  flutter_scripts: ^x.y.z  # 请替换为最新版本号

# Development dependencies are flutter tools that can be run via "flutter pub get"
# for development. They are not included in your app's build.
dev_dependencies:
  flutter_test:
    sdk: flutter

# For information on the generic Dart part of this file, see the
# following page: https://dart.dev/tools/pub/pubspec

# The following section is specific to Flutter.
flutter:
  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  # assets:
  #   - images/a_dot_burr.jpeg
  #   - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
  #
  # For details regarding fonts from package dependencies,
  # see https://flutter.dev/custom-fonts/#from-packages

flutter_scripts:
  custom:
    script: tools/custom_script.dart

tools/custom_script.dart

// tools/custom_script.dart

void main() {
  print('Hello from custom script!');
  // 在这里添加你的自定义逻辑
}

通过这种方式，你可以轻松地在Flutter项目中定义和执行自定义的Dart脚本。
