sendTextMessage: Send a text message to a single recipient.
sendBulkMessages: Send a text message to multiple recipients.
sendMediaUrl: Send media using a URL.
sendMedia: Send media using raw Uint8List (web-optimized).
sendMediaFromFile: Send media using a File (mobile-optimized).
sendContact: Share a contact as a vCard.
sendLocation: Share a location pin.
sendGroupMessage: Send messages to a WhatsApp group.

Example Usage
Below are examples using the API base URL https://noti-fire.com/api and a sample device ID.
Send Text Message
try {
  final response = await notiFireService.sendTextMessage(
    to: '+20xxxxxxxxx',
    message: 'Hello from Noti Fire API!',
  );
  print('Success: ${response.messageId}');
} catch (e) {
  print('Error: $e');
}

Send Bulk Messages
try {
  final response = await notiFireService.sendBulkMessages(
    message: 'Hello everyone!',
    numbers: ['+20xxxxxxxxx', '+20xxxxxxxxx'],
  );
  print('Success: ${response.messageId}');
} catch (e) {
  print('Error: $e');
}

Send Media (URL)
try {
  final response = await notiFireService.sendMediaUrl(
    to: '+20xxxxxxxxx',
    type: 'image',
    mediaUrl: 'https://example.com/image.jpg',
    caption: 'Test image',
  );
  print('Success: ${response.messageId}');
} catch (e) {
  print('Error: $e');
}

Send Media (File Upload - Web)
For web, use sendMedia with Uint8List from file_picker:
import 'package:file_picker/file_picker.dart';
import 'package:flutter/foundation.dart' show kIsWeb;

final result = await FilePicker.platform.pickFiles(
  type: FileType.custom,
  allowedExtensions: ['jpg', 'jpeg', 'png', 'gif', 'mp4', 'mov', 'avi', 'mkv', 'mp3', 'wav', 'pdf'],
  allowMultiple: false,
);

if (result != null && result.files.single.bytes != null && kIsWeb) {
  try {
    final response = await notiFireService.sendMedia(
      to: '+20xxxxxxxxx',
      bytes: result.files.single.bytes!,
      fileName: result.files.single.name,
      caption: 'Test media (web)',
    );
    print('Success: ${response.messageId}');
  } catch (e) {
    print('Error: $e');
  }
}

Send Media (File Upload - Mobile)
For mobile, use sendMediaFromFile with a File:
import 'package:file_picker/file_picker.dart';
import 'package:universal_io/io.dart';

final result = await FilePicker.platform.pickFiles(
  type: FileType.custom,
  allowedExtensions: ['jpg', 'jpeg', 'png', 'gif', 'mp4', 'mov', 'avi', 'mkv', 'mp3', 'wav', 'pdf'],
  allowMultiple: false,
);

if (result != null && result.files.single.path != null) {
  try {
    final file = File(result.files.single.path!);
    final response = await notiFireService.sendMediaFromFile(
      to: '+20xxxxxxxxx',
      file: file,
      caption: 'Test media (mobile)',
    );
    print('Success: ${response.messageId}');
  } catch (e) {
    print('Error: $e');
  }
}

try {
  final response = await notiFireService.sendContact(
    to: '+20xxxxxxxxx',
    contactName: 'John Doe',
    contactPhone: '+201111111111',
  );
  print('Success: ${response.messageId}');
} catch (e) {
  print('Error: $e');
}

Send Location
try {
  final response = await notiFireService.sendLocation(
    to: '+20xxxxxxxxx',
    latitude: 30.4589847,
    longitude: 31.1472218,
  );
  print('Success: ${response.messageId}');
} catch (e) {
  print('Error: $e');
}

Send Group Message
try {
  final response = await notiFireService.sendGroupMessage(
    groupId: '120363406573708642',
    type: 'text',
    text: 'Hello group members!',
  );
  print('Success: ${response.messageId}');
} catch (e) {
  print('Error: $e');
}

400 Bad Request: Invalid parameters (e.g., unsupported file type, exceeded length limits).
