iOS项目中用pod方式集成flutter

第一步，将flutter项目创建在iOS项目同目录中

注意：此处创建的是flutter module，不是flutter project

flutter create -t module flutter_lab

第二步，在podfile文件中加入以下脚本，然后pod install

flutter_application_path = '../flutter_lab/'

target 'Test' do

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

end

第三步，Run Script

# 删除本地Flutter文件夹
rm -rf -- "$SOURCE_ROOT/Flutter"
# 再生成Flutter文件夹
mkdir -p "$SOURCE_ROOT/Flutter"

# 编译生成
"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build

# 将胶水文件copy到本地文件夹
cp -r -- "$FLUTTER_APPLICATION_PATH/.ios/Flutter/flutter_assets" "$SOURCE_ROOT/Flutter"
cp -r -- "$FLUTTER_APPLICATION_PATH/.ios/Flutter/App.framework" "$SOURCE_ROOT/Flutter"

第四步，编译iOS项目，将编译生成flutter文件导入iOS项目

目录中会生成flutter文件夹，在iOS工程目录中新建Flutter文件夹，将App.framework和flutter_assets导入到刚建立的Flutter文件夹，切记flutter_assets使用Creat folder references方式导入

第五步，导入App.framework

第五步，改造AppDelegate

#import <UIKit/UIKit.h>
#import <Flutter/Flutter.h>

@interface AppDelegate : FlutterAppDelegate

@end


#import "AppDelegate.h"
#import <FlutterPluginRegistrant/GeneratedPluginRegistrant.h>

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [GeneratedPluginRegistrant registerWithRegistry:self];
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

@end
