Flutter 项目结构的区别

1. 如果需要调用原生代码，请创建一个plugin类型的项目开发。
2. 如果需要调用C语言，请参考文档：Flutter项目中调用C语言
3. plugin 其实是 package 的一种，全称是 plugin package，我们简称为 plugin，中文叫插件。

其实就是一个内嵌的iOS工程

可以通过xcode 打开 Runner.xcworkspace 进行项目配置

  # This section identifies this Flutter project as a plugin project.# The 'pluginClass' specifies the class (in Java, Kotlin, Swift, Objective-C, etc.)# which should be registered in the plugin registry. This is required for# using method channels.# The Android 'package' specifies package in which the registered class is.# This is required for using method channels on Android.# The 'ffiPlugin' specifies that native code should be built and bundled.# This is required for using `dart:ffi`.# All these are used by the tooling to maintain consistency when# adding or updating assets for this project.plugin:platforms:android:package: com.example.plugin_demopluginClass: PluginDemoPluginios:pluginClass: PluginDemoPlugin

flutter create <output directory>-h, --help                   Print this usage information.--[no-]pub               Whether to run "flutter pub get" after the projecthas been created.(defaults to on)--[no-]offline           When "flutter pub get" is run by the createcommand, this indicates whether to run it inoffline mode or not. In offline mode, it will needto have all dependencies already available in thepub cache to succeed.--[no-]overwrite         When performing operations, overwrite existingfiles.--description            The description to use for your new Flutterproject. This string ends up in the pubspec.yamlfile.(defaults to "A new Flutter project.")--org                    The organization responsible for your new Flutterproject, in reverse domain name notation. Thisstring is used in Java package names and as prefixin the iOS bundle identifier.(defaults to "com.example")--project-name           The project name for this new Flutter project. Thismust be a valid dart package name.
-i, --ios-language           The language to use for iOS-specific code, eitherObjective-C (legacy) or Swift (recommended).[objc, swift (default)]
-a, --android-language       The language to use for Android-specific code,either Java (legacy) or Kotlin (recommended).[java, kotlin (default)]--platforms              The platforms supported by this project. Platformfolders (e.g. android/) will be generated in thetarget project. This argument only works when"--template" is set to app or plugin. When addingplatforms to a plugin project, the pubspec.yamlwill be updated with the requested platform. Addingdesktop platforms requires the correspondingdesktop config setting to be enabled.[ios (default), android (default), windows(default), linux (default), macos (default), web(default)]
-t, --template=<type>        Specify the type of project to create.[app]              (default) Generate a Flutter application.[module]           Generate a project to add a Flutter module to anexisting Android or iOS application.[package]          Generate a shareable Flutter project containingmodular Dart code.[plugin]           Generate a shareable Flutter project containing anAPI in Dart code with a platform-specificimplementation through method channels for Android,iOS, Linux, macOS, Windows, web, or any combinationof these.[plugin_ffi]       Generate a shareable Flutter project containing anAPI in Dart code with a platform-specificimplementation through dart:ffi for Android, iOS,Linux, macOS, Windows, or any combination of these.[skeleton]         Generate a List View / Detail View Flutterapplication that follows community best practices.-s, --sample=<id>            Specifies the Flutter code sample to use as the"main.dart" for an application. Implies"--template=app". The value should be the sample IDof the desired sample from the API documentationwebsite (https://api.flutter.dev/). An example canbe found at:https://api.flutter.dev/flutter/widgets/SingleChildScrollView-class.html
-e, --[no-]empty             Specifies creating using an application templatewith a main.dart that is minimal, including nocomments, as a starting point for a newapplication. Implies "--template=app".--list-samples=<path>    Specifies a JSON output file for a listing ofFlutter code samples that can be created with"--sample".
