reflectable | Header only macro powered reflection for C | Reflection library

I have a project that must be parsed before original compilation. It's needed for reflection purposes. In short I want to check edited .h files for some attributes in the code and gather info about it to generate specific include files. For example reflectable classes/fields/methods will be marked as META(parameters...). This macro will be defined like this #define META(...) __attribute__(annotate("reflectable")).

The code should looks like this (similar to Qt QObject or Unreal Engine 4):

Have a query, let it be

I want to achieve reflection in a cross-platform (iOS, Android) project using Flutter and the Reflectable package. To keep the binaries short, this package uses code generation.

However, following the tutorial/readme of this package, I am not able to generate the needed code, in this case the file main.reflectable.dart. While I have reached the point where things work without error, code generation concludes with the statement:

I came to know that dart mirrors is disabled in flutter but hope that there might be some alternate way to achieve. Mirrors must not be disabled in flutter, it is an important & must have feature.

I am currently trying to implement google sign in and authentication within my app. I have set up a project and created an app in Firebase, put the google-services.json in the application, added the necessary plugin to build.gradle, and set the SHA-1 key in firebase. Email authentication is working great, however google authentication is causing problems.

All authentication is done from an 'authentication' package I have created. It contains an authentication page and performs all auth logic. The 'main' flutter app which is run, imports this package for use. This 'main' project's build.gradle files contain the additions for the google services plugin (com.google.gms:google-services:4.3.2). Once the 'main' project is run it checks if the user is currently logged in. If not it passes control to the 'authentication' package to display an auth screen and handle the login.

The problem occurs after selecting the google account I want to login with. Once the account is selected, the account selection dialog closes and nothing happens after that. The user is not authenticated (confirmed in Firebase), no exceptions are thrown, and the try-catch surrounding everything does not catch any exceptions. It seems as if all execution of the function halts. I can still move through the app, but the sign in method never finishes execution.

You can see the sign in method below. After the execution of the line final GoogleSignInAccount googleSignInAccount = await googleSignIn.signIn(); execution does not continue for some reason.

Say I have a class:

I am kind of new to flutter developments. Above error is getting to show up when import 'package:socket_io/socket_io.dart'; from the package socket_io: ^0.9.0+1

i'm trying to connect node js back end socket to flutter app. I don't use a emulator but a Samsung Tab as a external device.

here is my client program

My aplogoze for the original question. I'm getting confused. This is my actual question.

I have a situation where I need to use some defined classes as an object of type Type and instantiate it's object instance. As for now, I'm using self defined static instantiator function to call the constructor and it's working good. So I can just call Function.apply() to create an object. Rather than doing that, is there any way I can use the class's Type to emulate the class's constructor.

What have I tried? They say to use Mirror, a solution for Dart's reflection.

import 'dart:mirrors' have failed with error

Target of URI doesn't exists

Or at least if it's not ready provided I don't know where to get the package.

import 'package:reflectable/mirrors.dart' with package from git://github.com/dart-lang/reflectable.git only defines all Mirror implemented classes, but function reflect is missing.

I'm trying to parse strings that looks like these:
