iOS 集成Flutter

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

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（加粗部分）

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

@property (nonatomic,strong) FlutterEngine *flutterEngine;

@end

2、

#import// 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];

具体图如下：

备注：

如果报错：

dyld: Library not loaded: @rpath/App.framework/App.....

解决方案：

1、卸载cocoapods

sudo gem uninstall -n /usr/local/bin cocoapods cocoapods-core cocoapods-deintegrate cocoapods-downloader cocoapods-plugins cocoapods-search cocoapods-stats cocoapods-trunk cocoapods-try

2、卸载 ruby-macho

sudo gem uninstall ruby-macho

3、重新安装pod

sudo gem install -n /usr/local/bin cocoapods

4、cd到iOS项目目录下删除原有的pods、Podfile.lock、.xcworkspace，重新pod install
