这篇博客介绍了如何在Flutter应用中嵌入iOS自定义View，并实现两端的参数传递和通信。通过在AppDelegate中注册、编辑Flutter页面，创建MethodChannel，实现了Flutter向iOS View发送消息并接收参数的功能。
import Foundation
import Flutter
class MyFlutterViewFactory: NSObject,FlutterPlatformViewFactory {
var messenger:FlutterBinaryMessenger
init(messenger:FlutterBinaryMessenger) {
self.messenger = messenger
super.init()
}
func create(withFrame frame: CGRect, viewIdentifier viewId: Int64, arguments args: Any?) -> FlutterPlatformView {
return MyFlutterView(frame,viewID: viewId,args: args,messenger: messenger)
}
func createArgsCodec() -> FlutterMessageCodec & NSObjectProtocol {
return FlutterStandardMessageCodec.sharedInstance()
}
}
3.4 在 AppDelegate 中注册
import UIKit
import Flutter
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
