iOS已有项目集成Flutter

1.创建一个目录,把已有的安卓项目复制到里面

2.用命令行,cd进来这个目录,flutter create --template module my_flutter,就会创建一个my_flutter的工程

如下图所示

3.如果iOS项目里面没用cocoapod那么新建一个Podfile文件

4.Podfile文件里面的内容大致如下

source 'https://github.com/CocoaPods/Specs.git'

platform :ios, '9.0'

target 'QiMing' do

  use_frameworks!

#flutter_application_path = '../my_flutter'

#eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)

flutter_application_path = '../my_flutter'

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

install_all_flutter_pods(flutter_application_path)

end

5.如果iOS项目之前就是cocoapod项目,直接复制代码进去就行,如下

复制进去的代码如下
#flutter_application_path = '../my_flutter'

#eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)

flutter_application_path = '../my_flutter'

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

install_all_flutter_pods(flutter_application_path)

6.cd进去iOS工程,pod install

等待完成.....

完成会如下图所示

7.AppDelegate.h配置

#import

#import

@interface AppDelegate : FlutterAppDelegate <UIApplicationDelegate>

//@property (strong, nonatomic) UIWindow *window;

@property (nonatomic,strong) FlutterEngine *flutterEngine;

@end

8.AppDelegate.m配置

#import <FlutterPluginRegistrant/GeneratedPluginRegistrant.h>

- (BOOL)application:(UIApplication*)applicationdidFinishLaunchingWithOptions:(NSDictionary*)launchOptions {

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

    [self.flutterEngine runWithEntrypoint:nil];

    [GeneratedPluginRegistrant registerWithRegistry:self.flutterEngine];

    return YES;

}

//提示,如果不配置AppDelegate的代码,那么ios页面push flutter页面会有延迟,延迟中会出现app过渡页,体验不好

9.页面跳转

//    //设置路由参数

    //    [flutterViewController setInitialRoute:@"route"];

FlutterEngine *flutterEngine = [(AppDelegate *)[[UIApplication sharedApplication] delegate] flutterEngine];

    FlutterViewController *flutterViewController = [[FlutterViewController alloc] initWithEngine:flutterEngine nibName:nil bundle:nil];

    flutterViewController.title=@"flutterTitle";

    [selfpushVC:flutterViewControlleranimated:NO];
