  friends_badge: ^0.1.0

Then, import the package in your Dart code:

import 'package:friends_badge/friends_badge.dart';

Now, you can use the FriendsBadge class to create a BadgeImage and write it to your badge:

// First, create a BadgeImage from an image.
final image = FriendsBadge.createBadgeImage(yourImage);

// Then, write the image to the badge over NFC.
await FriendsBadge.writeOverNfc(image);

// Optionally, you can show a loading indicator while writing the image.

  context: context,
  job: FriendsBadge.writeOverNfc(image),
);

The showLoading method will display a progress indicator while the image is being written to the badge.
