How to Use Customised pub.dev Packages for Your Flutter Project

Step 1: Add the Package to Your Project

1. Open your pubspec.yaml file.
2. Add the desired package under the dependencies section and specify the version.
3. Run flutter pub get to download the package. This will make the package available locally in your project.

Step 2: Access the Hidden .pub-cache Folder

1. Open the "Finder" on your Mac.
2. In the menu bar, click on "Go" and select the "Home" directory.

• Press Command + Shift + . (the period key) to display hidden files and folders.

Step 3: Locate and Copy the Package

1. Navigate to the .pub-cache/hosted/pub.dev folder.
2. Find the package you want to modify, and copy the entire package folder.

(Ex: webview_flutter-4.7.0)

Note: You can skip the above steps and download the package directly from the Git repository. In cases where only the latest version is available, you can follow the above steps to download the correct version.

Step 4: Move the Package to Your Project

1. Paste the copied package folder into the root directory of your project. The package should now be visible in your project’s root folder.

Step 5: Update pubspec.yaml to Use the Local Package

1. Open the pubspec.yaml file.
2. Remove the version number for the package.
3. Replace it with the local path to the package folder you just pasted, like this:

dependencies:
  package_name:
    path: ./package_name        

Ex:

Step 6: Run pub get and Clean Up

1. Run flutter pub get to update your dependencies with the local package.
2. Optional: If desired, you can delete the example and test folders from the local package to avoid any potential errors.

Step 7: Make your changes to the local package.
