iOS 项目嵌入Flutter 运行(最新推荐)
<div id="navCategory"><h5 class="catalogue">目录</h5><ul class="first_class_ul"><li>一 创建Flutter 模块</li><li>二 嵌入到iOS 项目</li><li>三 iOS 项目中调用</li></ul></div><p class="maodian"></p><h2>一 创建Flutter 模块</h2><p>命令行</p>
<div class="jb51code"><pre class="brush:bash;">flutter create --template module my_flutter</pre></div>
<p>创建完成后，该模块和普通的Flutter项目一直，可以通过Android Studio或VSCode打开、开发、运行；</p>
<ul><li>和之前项目不同的iOS和Android项目是一个隐藏文件，并且我们通常不会单独打开它们再来运行；</li><li>它们的作用是将Flutter Module进行编译，之后继承到现有的项目中</li></ul>
<div class="jb51code"><pre class="brush:plain;">my_flutter/
├── .ios/
├── .android/
├── lib/
│ └── main.dart
├── test/
└── pubspec.yaml</pre></div>

<p class="maodian"></p><h2>二 嵌入到iOS 项目</h2>
<p>主要是通过pod 进行设置，之后pod install</p>
<p>注意my_flutter 的路径对不对</p>
<div class="jb51code"><pre class="brush:plain;">platform :ios, '12.0'
# 添加模块所在路径
flutter_application_path = '../my_flutter'
load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')
target 'FlutterHybridDemo' do
# Comment the next line if you don't want to use dynamic frameworks
use_frameworks!
# 安装Flutter模块
install_all_flutter_pods(flutter_application_path)
# Pods for FlutterHybridDemo
end
post_install do |installer|
flutter_post_install(installer) if defined?(flutter_post_install)
end</pre></div>
<p class="maodian"></p><h2>三 iOS 项目中调用</h2>
<p>为了在既有的iOS应用中展示Flutter页面，需要启动 Flutter Engine和 FlutterViewController</p>
<p>AppDelegate 中设置代码</p>
<div class="jb51code"><pre class="brush:java;">import UIKit
import FlutterPluginRegistrant
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
// 1.创建一个FlutterEngine对象
lazy var flutterEngine = FlutterEngine(name:"my flutter engine")
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: ?) -> Bool {
// Override point for customization after application launch.
// 2 启动
flutterEngine.run()
return true
}</pre></div>
<p>在ViewControlelr 设置的代码</p>
<div class="jb51code"><pre class="brush:java;">import UIKit
import Flutter
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let btn = UIButton(type: UIButton.ButtonType.custom)
btn.setTitle("加载flutter", for: UIControl.State.normal)
btn.frame = CGRect(x: 50, y: 50, width: 200, height: 50)
btn.backgroundColor = UIColor.blue
btn.addTarget(self, action: #selector(showFlutter), for: UIControl.Event.touchUpInside)
view.addSubview(btn)
}
@objc func showFlutter(){
let flutterEngine = (UIApplication.shared.delegate as! AppDelegate).flutterEngine
let flutterController = FlutterViewController(engine:flutterEngine, nibName: nil, bundle: nil)
present(flutterController, animated: true)
}
}</pre></div>
<p>显示的结果 顺利加载出flutter 的页面</p>
