Install libraries

In Flutter, you can install libraries (or packages) using pub.dev, the official package repository for Dart and Flutter.

---

Steps to Install a Library in Flutter

1. Go to the Official Source
   Visit https://pub.dev – this is the official source for Flutter libraries/packages.

---

2. Search for the Library

   • Use the search bar to find the package you need.

   • Example: Searching for http for handling HTTP requests.

---

3. Add the Library to pubspec.yaml
   In your Flutter project, open the pubspec.yaml file and add the library under dependencies:

   Copydependencies:
     flutter:
       sdk: flutter
     {exampleLibraryName}: ^version  
   

   ⚠️ Note: Always check for the latest stable version on pub.dev.

---

4. Run flutter pub get
   In the terminal, navigate to your project directory and run:

   Copyflutter pub get
   

   This downloads the package and makes it available for use.

How to Check All Installed Libraries

To view all the libraries/packages installed in your project, check the pubspec.lock file.
