Direct REST API Integration

The mobile app communicates directly with your live TempoMail backend API endpoints with zero middleware required.

lib/services/api_service.dart
Flutter 3.x • REST JSON
// 1. Generate new temporary address
Future<TempoMailbox> createMailbox({String? customPrefix}) async {
  final response = await http.post(
    Uri.parse('$apiBaseUrl/api/v1/mailbox/create'),
    headers: {'X-API-KEY': appApiKey},
    body: {'prefix': customPrefix ?? ''},
  );
  return TempoMailbox.fromJson(jsonDecode(response.body));
}

// 2. Poll inbox messages with sub-second stream listener
Stream<List<TempoMessage>> streamMessages(String emailToken) async* {
  while (true) {
    final messages = await fetchMessages(emailToken);
    yield messages;
    await Future.delayed(const Duration(seconds: 3));
  }
}
State Management Built using Riverpod / Bloc for predictable, reactive, and testable app lifecycle.
Local Persistence Encrypted SQLite / Hive storage preserving active addresses even across app restarts.
Zero Backend Alteration Uses the standard TempoMail REST endpoints out of the box. Zero backend hacks.
