1.在iOS項(xiàng)目所在的同級(jí)目錄下創(chuàng)建flutter_module獨(dú)立的項(xiàng)目

?在終端上輸入命令$ flutter create -t module flutter_module

2.在IOS項(xiàng)目的Podfile中添加以下代碼，給工程target配置flutter相關(guān)的pods

?target 'iOSFlutterDemo' do
?flutter_application_path = '../flutter_module'
?load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')
?install_all_flutter_pods(flutter_application_path)
end

3.在flutter_module目錄上執(zhí)行'flutter build ios'

$ flutter build ios （flutter項(xiàng)目有修改的東西更新之后 如果要同步到iOS項(xiàng)目 需要重新 執(zhí)行 flutter build ios）

4.在IOS工程目錄上執(zhí)行'pod install'，完成之后就可以在IOS工程中看到flutter及依賴庫的Framework和源碼

pod install

5.修改bitcode

6.在項(xiàng)目中的一個(gè)控制器中導(dǎo)入Flutter 創(chuàng)建一個(gè)按鈕點(diǎn)擊進(jìn)入flutter頁面

#import "HomeViewController.h"
@import Flutter;

@interface HomeViewController ()
@property (nonatomic, strong) FlutterEngine *flutterEngine;
@property(nonatomic, strong) FlutterViewController* flutterVc;
@property(nonatomic, strong) FlutterBasicMessageChannel * msgChannel;
@end

@implementation HomeViewController

- (void)viewDidLoad {
?? ?
??? [super viewDidLoad];

?? ?
??? [self.msgChannel setMessageHandler:^(id? _Nullable message, FlutterReply? _Nonnull callback) {
??????? NSLog(@"收到Flutter的：%@",message);
??? }];
?? ?
}
#pragma mark - 調(diào)用flutter的頁面
- (void)goFlutter{
??? [self.navigationController pushViewController:self.flutterVc animated:YES];
}

-(FlutterEngine *)flutterEngine{
??? if (!_flutterEngine) {//main對(duì)應(yīng)main.dart

??????? FlutterEngine * engine = [[FlutterEngine alloc] initWithName:@"main"];
??????? if (engine.run) {
??????????? _flutterEngine = engine;
??????? }
??? }
??? return _flutterEngine;
}
