SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides a clear, maintainable implementation plan for an in-app wallet and payments feature so developers can implement secure top-ups, transaction histories, and multiple payment methods without re-designing architecture.

Core Features & Use Cases

  • Wallet state & balance management: Defines WalletEntity with balance, currency, and pending balance and mandates refreshing balances after payments.
  • Transaction management: Supports transaction entities, paginated history, and transaction detail pages covering topups, payments, refunds, bonuses, and withdrawals.
  • Top-up and payment method flows: Details creation of top-up requests, deep link handling for external payment apps (MoMo, ZaloPay, VNPAY), payment URL launching, and updating balance after callbacks.
  • Presentation and orchestration: Specifies Cubits (WalletCubit, TopUpCubit), pages, widgets, and rules for secure handling of payment data and deep link integration.

Quick Start

Open the WalletPage, choose an amount and payment method, create a top-up request, and follow the payment app deep link to complete and refresh the balance.

Manage in-app wallet state by defining a WalletEntity with balance, currency, and pending balance. Use WalletCubit to orchestrate state and mandate refreshing balances immediately after payment callbacks complete.

Does this wallet implementation support multiple payment methods for ride-hailing and food delivery apps?▼

Yes, this wallet implementation supports ride-hailing and food delivery apps by detailing payment method selection, top-up creation, and external payment app integration. It securely handles multiple payment methods through deep link flows.

How do I structure a paginated transaction history for a Flutter wallet?▼

Structure paginated transaction history by implementing transaction entities that cover topups, payments, refunds, bonuses, and withdrawals. Use repository patterns to fetch and display these details on transaction pages.

What architecture is needed to securely handle payment data in a Flutter wallet?▼

Securely handle payment data by structuring your Flutter wallet with use cases, repositories, and cubits. This architecture ensures secure top-up creation and safe deep link integration for external payment processing.
