Flutter使用pub工具来管理包，可以通过pubspec.yaml文件来指定项目所需的依赖包，并通过运行flutter pub get命令来下载和安装这些依赖包。
在项目根目录下打开terminal，执行以下命令：：
flutter pub add pinyin
1
flutter 包管理工具会自动下载pinyin (opens new window)包最新版本，并且更新pubspec.yaml:
dependencies:
pinyin: ^3.2.0 #latest version

使用pinyin包：
// Import package
import 'package:pinyin/pinyin.dart';
void main() {
String text = "你好，拼音！";
String pinyin = PinyinHelper.getPinyin(text);
print('pinyin: $pinyin'); // pinyin: nihao， pinyin!
}

🌙 包管理配置文件pubspec.yaml
pubspec.yaml详解：
# 应用名称
name: hello_flutter
# 应用描述
description: "A new Flutter project."
# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
# 发布配置
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 1.2.43
# 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 is used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
# In Windows, build-name is used as the major, minor, and patch parts
# of the product and file versions while build-number is used as the build suffix.
# 应用包版本，说明：版本号 x.y.z+m 其中 m 是构建版本，可以使用 --build-name/--build-number 构建参数覆盖，在 android 中 build-name 当作 versionName使用，build-number 当作versionCode使用
version: 1.0.0+1
# 应用或包的开发环境 flutter的SDK版本在此区间 这个会影响到下面引用的插件依赖库
environment:
sdk: '>=3.3.1 <4.0.0'
# Dependencies specify other packages that your package needs in order to work.
# To automatically upgrade your package dependencies to the latest versions
# consider running `flutter pub upgrade --major-versions`. Alternatively,
# dependencies can be manually updated by changing the version numbers below to
# the latest version available on pub.dev. To see which dependencies have newer
# versions available, run `flutter pub outdated`.
# 应用或包依赖的其他包或插件
dependencies:
flutter:
sdk: flutter
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
# 默认加载的IOS图标
cupertino_icons: ^1.0.6
# 开发环境依赖的工具包（而不是Flutter应用本身依赖的包）
dev_dependencies:
flutter_test:

# The "flutter_lints" package below contains a set of recommended lints to
# encourage good coding practices. The lint set provided by the package is
# activated in the `analysis_options.yaml` file located at the root of your
# package. See that file for information about deactivating specific lint
# rules and activating additional ones.
flutter_lints: ^3.0.0
# For information on the generic Dart part of this file, see the

# 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.
# 默认生成--使用android material-design 图标
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:
# 字体库添加
# 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
