⚙️ Usage

Simply import the package to use it:

import 'package:simple_gravatar_fetch/simple_gravatar_fetch.dart';

1. Getting an Avatar Image (getGravatar)

Fetches the user's profile picture as a Uint8List. This can be used directly with Image.memory in Flutter.

import 'dart:typed_data'; // For Uint8List

void main() async {
  const email = '[e-mail]';

  final Uint8List? imageData = await getGravatar(
    email,
    size: 200,
    defaultImage: 'identicon', // Generate an identicon if not found
    rating: 'g',
  );

  if (imageData != null) {
    print('Image fetched successfully. Size: ${imageData.lengthInBytes} bytes');
    // In Flutter:
    // return Image.memory(imageData);
  } else {
    print('Failed to fetch image.');
  }
}

Saving the Avatar to a File

The getGravatar function also allows you to save the image directly to disk.

await getGravatar(
  '[e-mail]',
  size: 500,
  saveToFile: true,
  outputPath: 'profile_picture.jpg',
);

print('Image saved to profile_picture.jpg');

2. Getting Profile Information (getGravatarProfile)

Use this to fetch a user's public profile (as JSON), which may include their name, location, "about me" text, etc.

void main() async {
  // An email known to have a public profile (for testing)
  const email = '[e-mail]';

  final profileData = await getGravatarProfile(email);

  if (profileData != null) {
    // Gravatar returns data inside an 'entry' list
    if (profileData.containsKey('entry') &&
        (profileData['entry'] as List).isNotEmpty) {
      final entry = (profileData['entry'] as List)[0] as Map<String, dynamic>;

      print('Display Name: ${entry['displayName']}');
      print('Location: ${entry['currentLocation']}');
      print('About Me: ${entry['aboutMe']}');
    }
  } else {
    print('No profile found for this email (404).');
  }
}
