1、第一步：

在iOS项目的同级目录下创建flutter工程

flutter create -t module flutter_library

如图的项目位置.png

2、第二步：

cd flutter_library

flutter build ios --debug --no-codesign

或

flutter build ios --release --no-codesign

等待编译完成

3、第三步：

在iOS项目中添加

platform :ios,'9.0'

flutter_application_path ='../flutter_library/' #相对目录

load File.join(flutter_application_path,'.ios','Flutter','podhelper.rb')

target 'FlutteriOS' do

use_frameworks!

install_all_flutter_pods(flutter_application_path)

Pods for FlutteriOS

end

然后pod install
这时候基本完成了配置，具体就是iOS怎么调用flutter的项目

4、第四步：

import

@interface AppDelegate : FlutterAppDelegate <UIApplicationDelegate>

@property (nonatomic,strong) FlutterEngine *flutterEngine;

@end

2、

import<FlutterPluginRegistrant/GeneratedPluginRegistrant.h>// 如果你需要用到Flutter插件时

• (BOOL)application:(UIApplication)applicationdidFinishLaunchingWithOptions:(NSDictionary)launchOptions {

  self.flutterEngine = [[FlutterEngine alloc] initWithName:@"io.flutter" project:nil];

   [self.flutterEngine runWithEntrypoint:nil];
  
   [GeneratedPluginRegistrant registerWithRegistry:self.flutterEngine]; //如果你需要用到Flutter插件时
  

  return YES;

}

5、第五步：

FlutterViewController* flutterViewController = [[FlutterViewController alloc] initWithProject:nil nibName:nil bundle:nil];
flutterViewController.navigationItem.title=@"Flutter Demo";
 [self presentViewController:flutterViewController animated:YES completion:nil];
