【问题描述】：

我正在将 Flutter 模块集成到 ios Native 项目中，我想从 ios Native 设置 Initial Route，但它不起作用，它使用默认路由。

ViewController.swift

import UIKit
import Flutter

class ViewController: UIViewController {

    let flutterEngine = FlutterEngine(name: "test")

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        flutterEngine.navigationChannel.invokeMethod("setInitialRoute", arguments:"/home")
        flutterEngine.run();

    }

    @IBAction func handleClick(_ sender: Any) {
        let flutterViewController = FlutterViewController(engine: flutterEngine, nibName: nil, bundle: nil)
        flutterViewController.setInitialRoute("/home")
        self.navigationController?.pushViewController(flutterViewController, animated: true)
    }

}

main.dart

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  final _route = <String, WidgetBuilder>{
    "/login": (context) => Login(),
    "/home": (context) => Home()
  };

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      routes: _route,
      title: "App", // Title ของหน้า
      home: Scaffold(
        // หน้าจอหลัก
        appBar: AppBar(
          title: Text("App Navi"),
        ),
        body: Login(),
      ),
    );
  }
}

【解决方案1】：

这个问题现在已经修复，从 Flutter 1.22 开始可以使用：

在初始化颤振引擎时：

let flutterEngine = FlutterEngine()
// FlutterDefaultDartEntrypoint is the same as nil, which will run main().
engine.run(
  withEntrypoint: FlutterDefaultDartEntrypoint, initialRoute: "/onboarding")

并且，直接在创建FlutterViewController时，

 let flutterViewController = FlutterViewController(
    project: nil,
    initialRoute: "/onboarding",
    nibName: nil,
    bundle: nil)
