Vihaya Flutter SDK

The official Flutter SDK for the Vihaya Events platform. Build attendee-facing mobile experiences with a tiny, fully-typed client.

Features

• List events and fetch full event metadata (agenda, speakers, sponsors, FAQs).
• Register attendees with custom fields, special pricing tiers, and team support.
• Verify Razorpay payments server-side.
• Full type safety across events, registrations, and pricing.

Install

dependencies:
  vihaya_sdk_flutter: ^0.1.0

Then:

flutter pub get

Quick start

Initialize the client

import 'package:vihaya_sdk_flutter/vihaya_sdk_flutter.dart';

final client = VihayaClient('YOUR_API_KEY');

// Or with custom configuration:
final customClient = VihayaClient(VihayaConfig(
  apiKey: 'YOUR_API_KEY',
  baseUrl: 'https://events.vihaya.app',
));

Get your API key from the Vihaya Developer Dashboard.

List events

try {
  final events = await client.events.list();
  for (final event in events) {
    print('${event.title} — ${event.location}');
  }
} on VihayaException catch (e) {
  print('Error: ${e.message} (status ${e.status})');
}

Fetch full event details

events.get() returns everything you need to render a rich event page or build a custom registration form — speakers, agenda, sponsors, FAQs, custom fields, and pricing tiers.

final event = await client.events.get('event-id');

print('Title: ${event.title}');
print('Mode: ${event.eventMode}');
print('Timezone: ${event.timezone}');

// Render speakers
event.speakerList?.forEach((s) => print('- ${s.name} (${s.role})'));

// Render agenda
event.agendaList?.forEach((a) => print('[${a.time}] ${a.title}'));

Mega events (parent events with sub-events)

If event.eventType == 'megaEvent', the event contains subEvents, each with its own pricing and custom fields.

if (event.eventType == 'megaEvent') {
  event.subEvents?.forEach((sub) {
    print('- ${sub.title} (${sub.isFree ? "Free" : "₹${sub.price}"})');
  });
}

Register an attendee

final registration = RegisterData(
  name: 'Anjali Mehta',
  email: 'anjali@example.com',
  phone: '+919820012345',
  customFields: {
    'T-Shirt Size': 'L',
    'College': 'Vihaya Institute',
  },
);

final response = await client.events.register('event-id', registration);

if (response['isPaid'] == true) {
  final orderId = response['orderId'];
  // Launch Razorpay checkout with this orderId, then:
  await client.payments.verify(
    paymentId: 'pay_xxx',
    orderId: orderId,
    signature: 'sig_xxx',
  );
} else {
  print('Registered! ID: ${response['registrationId']}');
}

Verify a payment (server-side)

await client.payments.verify(
  paymentId: 'pay_xxx',
  orderId: 'order_xxx',
  signature: 'sig_xxx',
);

Security: never hard-code your live secret key in a client build. Ship a restricted public key to the app and keep the secret on your backend.

Error handling

All API failures raise VihayaException:

try {
  await client.events.get('invalid-id');
} on VihayaException catch (e) {
  print('Message: ${e.message}');
  print('Status:  ${e.status}');
  print('Body:    ${e.data}');
}
