iOS混编flutter填坑记

之前写过一点点纯flutter的项目，最近比较好奇原生跟flutter混编，于是按照官方文档进行配置集成flutter到现有工程，集成后pod install报错，podfile中改为如下配置安装成功

target 'flutter-test' do
end
flutter_application_path = '../my_flutter'
eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)

原生项目中跳转flutter页面代码如下

- (IBAction)showFlutterOnClick:(UIButton *)sender {
    UIViewController *rootViewController = [[FlutterViewController alloc] initWithProject:nil nibName:nil bundle:nil];
    [self.navigationController pushViewController:rootViewController animated:YES];
}

点击跳转后可以跳转但是报错如下

2020-05-09 15:18:39.443794+0800 flutter-test[14940:251135] Failed to find assets path for "Frameworks/App.framework/flutter_assets"

百度后，应该增加如下脚本，具体配置参考Xcode 11.4 Support

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed
/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin

重新编译，点击跳转后正常显示flutter页面
