How to add a package from GitHub in Flutter?

Question

I need to use the latest source code of a package and the latest source hasn't been published yet. What should I write into pubspec.yaml to get a package in Github?

The code below doesn't work. It doesn't download the package and I can't import it into my source code

dependencies:   flutter:     sdk: flutter    carousel_pro:     git:       url: https://github.com/jlouage/flutter-carousel-pro.git 

Answer 1

Example of pubspec.yaml

---

Dependency with the specific branch:

dependencies:   flutter:     sdk: flutter    carousel_pro:     git:       url: git://github.com/jlouage/flutter-carousel-pro.git       ref: main # branch name 

---

Dependency with the specific commit:

dependencies:   flutter:     sdk: flutter    carousel_pro:     git:       url: git://github.com/jlouage/flutter-carousel-pro.git       ref: ea12e41 # commit hash 

Example of a file importing the package:

import 'package:carousel_pro/src/carousel_pro_widgets.dart'; import 'package:flutter/material.dart';  class NewsCarousel extends StatelessWidget {   @override   Widget build(BuildContext context) {     return SizedBox(       height: 200.0,       child: WidgetCarousel(         autoplay: false,         pages: [],       ),     );   } } 

Note: If your IDE doesn't see the package, try to restart it.

Answer 2

The above answers are correct but I have added some examples.

So to use pub/package/lib without publishing on pub.dev :

1. Local - Save in some local folder

dependencies:   library_name:    path: /path/to/library_name 

---

2. Hosted - Pushed on Github, Gitlab etc.

dependencies:   library_name:    git: https://github.com/username/library_name 

Or to target exact branch

dependencies:   library_name:    git:     url: https://github.com/username/library_name.git     ref: dev    #branch name 

Or to target exact commit

dependencies:   library_name:    git:     url: https://github.com/username/library_name.git     ref: e234072340    #commit reference id 

Where 'library_name' has to be the same as the 'name' declared in pubspec.yaml of that pub.
