Use Dart Console Project as a Dependency in Flutter Project

You can use your Dart console project as a dependency in your Flutter project by adding it as a path dependency or by publishing it as a package. Here’s how to do it step-by-step:

Option 1: Add as a Path Dependency

If your Dart console project is not published, you can reference it locally using a path.

Make Sure the Dart Console Project is a Package Ensure your Dart console project has a pubspec.yaml file and is structured as a Dart package. At a minimum, the pubspec.yaml should have:
```
name: my_dart_console_project
description: A reusable Dart project
version: 1.0.0
environment:
  sdk: '>=2.19.0 <3.0.0'
```
Add the Path Dependency In your Flutter project’s pubspec.yaml, add your Dart console project as a dependency using the path field. For example:
```
dependencies:
  flutter:
    sdk: flutter
  my_dart_console_project:
    path: ../path_to_your_dart_console_project
```
Replace ../path_to_your_dart_console_project with the actual relative path to your Dart project.
Run flutter pub get Navigate to your Flutter project folder in the terminal and run:
```
flutter pub get
```

Import and Use the Dart Package You can now import the library from your Dart console project in your Flutter app:

import 'package:my_dart_console_project/my_dart_console_project.dart';

void main() {
  // Call functions or classes from the Dart console project
}

Option 2: Publish to a Private or Public Repository

If you want the dependency to be reusable across multiple projects:

Publish the Dart Project to a Git Repository Push your Dart console project to a Git repository (e.g., GitHub, GitLab).

Reference it in pubspec.yaml Add the Git repository URL in your Flutter project’s pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter
  my_dart_console_project:
    git:
      url: https://github.com/username/my_dart_console_project.git
      ref: main

Run flutter pub get Fetch the dependency:
```
flutter pub get
```
Import and Use the Dependency Use it in the same way as the path dependency.

Option 3: Publish to Pub.dev (Optional)

If your Dart console project is generic and reusable for others, you can publish it to pub.dev:

Follow the steps in the Dart publishing guide.
Once published, reference it in your pubspec.yaml like this:
```
dependencies:
  my_dart_console_project: ^1.0.0
```
Run flutter pub get.

Debugging Tips

Ensure the console project doesn’t have Flutter dependencies unless needed, as Dart-only projects typically don’t require them.
If you face dependency version conflicts, align the environment SDK constraints between your Flutter project and Dart console project.
