Ios 集成 Flutter Frameworks

使用命令生成 frameworks flutter build ios-framework --xcframework --no-universal

生成 App.xcframework 和 Flutter.xcframework

拖拽 frameworks 到你的应用 target 编译设置的 General > Frameworks, Libraries, and Embedded Content 下，然后在 Embed 下拉列表中选择 “Embed & Sign”。
初始化flutterEngine

import UIKit
import Flutter

@main
class AppDelegate: FlutterAppDelegate {
    lazy var flutterEngine = FlutterEngine(name: "hgg_im")


    override func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
//        return true
        // Runs the default Dart entrypoint with a default Flutter route.
            flutterEngine.run();
            // Used to connect plugins (only if you have plugins with iOS platform code).
            return super.application(application, didFinishLaunchingWithOptions: launchOptions);
    }
}

启动页面

 let flutterEngine = (UIApplication.shared.delegate as! AppDelegate).flutterEngine
 let flutterViewController =
         FlutterViewController(engine: flutterEngine, nibName: nil, bundle: nil)
 //flutterViewController.modalPresentationStyle = UIModalPresentationStyle.fullScreen;
 present(flutterViewController, animated: true, completion: nil)
