Hi, We can provide a production-ready Flutter/Dart codebase for your mobile banking application with a single shared codebase for iOS and Android. Our team can implement phone + OTP authentication, real-time balance, deposits, withdrawals, user-to-user transfers and multi-currency conversion for USD, EUR, XOF, UGX, ZAR, KES and AED. We’ll follow clean architecture with consistent state management, API service layers/stubs, secure configuration, documentation and unit tests for the key flows. -/ Do you already have the banking APIs available, or should we structure the service layer around your expected API contracts? -/ Should the currency conversion use your existing exchange-rate API, or do you need us to include the conversion engine/API integration? -/ Do you require biometric authentication or device security in addition to phone + OTP? We can deliver the complete source code, assets, README, environment configuration and test coverage, with the same Flutter codebase prepared for both iOS and Android. Best regards, Asif Ali Zaman WebExert Budget and Duration: TBD

@AITSoft

Hi, I understand you need a complete Dart and Flutter banking app that works consistently on both iPhone and Android. I will provide phone-number OTP login, balance views, deposits, withdrawals, user transfers, and multi-currency conversion for USD, EUR, XOF, UGX, ZAR, KES, and AED. The code will use clean architecture with one consistent state-management approach, clear API service stubs, environment settings, README instructions, and unit tests for authentication, transfers, and conversion. I will also make sure the project builds on the latest stable Flutter version and can be checked in an emulator or simulator. Which existing banking APIs and authentication, exchange-rate, deposit, withdrawal, and transfer specifications should the service stubs follow? The source code and assets will be delivered for your team to connect with the existing banking APIs, with no extra licensing fees.

Hi there. Deploying a mobile banking app across West Africa requires a bulletproof, unified codebase to avoid security vulnerabilities and platform-specific feature gaps during compliance checks, but managing multi-currency conversions and strict OTP authentication without proper state management often leads to race conditions and delayed deployment. I have a production-ready, clean-architecture Flutter codebase that compiles seamlessly for both iOS and Android, featuring a robust multi-currency engine covering USD, EUR, XOF, UGX, ZAR, KES, and AED, alongside seamless phone-number OTP flows and clean API service stubs ready for your backend integration. Here are my questions: 1. Which state management approach do you prefer for this codebase, such as Bloc or Riverpod? 2. Are the banking APIs ready with documentation for immediate wiring once we hand over the source code? Let's discuss your project now!

@TechizeBuilder

Dear Client, I read "Flutter Banking App Source Code" carefully and understand you want a single Flutter codebase that runs smoothly on both Android and iOS. My hands-on experience with Mobile App Development, iPhone, Android, Mobile App Testing, Flutter aligns directly with what you need. I've shipped Flutter apps from scratch to store launch — clean architecture, smooth animations, native-feeling UI and solid API integrations — that stay easy to maintain as features grow. A few quick questions to get us started: 1. Do you need Android, iOS, or both from day one? 2. Are UI designs ready, or should I design the screens as well? 3. Is there an existing backend/API, or should I build that too? Thanks & Regards, Deepak

@mughiraaa

hi, i can build this as a single pure Flutter and Dart codebase for both iOS and Android, with clean architecture and no platform feature gaps. i have experience with Flutter, OTP authentication, financial workflows, API integrations, wallet and payment systems and multi currency applications. i can structure the app with consistent state management, clear service classes and API stubs so your backend team can connect the existing banking APIs without reworking the frontend. the core flow will cover phone and OTP authentication, real time balances, deposits, withdrawals, user to user transfers and conversion across USD, EUR, XOF, UGX, ZAR, KES and AED. i’ll also include the README, environment configuration and unit tests for authentication, transfers and conversion logic. do you already have the banking API documentation and endpoints ready, or should i first structure the service layer around your expected API contracts? let’s have a quick meeting to go through the banking flows and API requirements before we finalise the implementation plan.

@ranjika08

Your requirement is really about buying a banking-ready Flutter foundation that your backend team can adopt without reworking the whole app later. In this kind of build, the important part is not only the screens for balance, deposit, withdrawal, transfer, and conversion, but making sure OTP login, transaction flows, and multi-currency logic are separated cleanly so one codebase runs properly on both iOS and Android. I’ve handled app structures where the deliverable had to be source-code-first: organized layers, consistent state management, API service stubs, and tests that prove the main flows instead of leaving everything as UI-only. That fits well here because your acceptance depends on clean builds, readable setup instructions, and a handoff that lets another technical team continue development easily. I can also keep the project ready for full IP transfer with no dependency mess. - Do you already have a preferred state management pattern between Bloc, Riverpod, or Provider, or should I choose the most maintainable fit for this scope? - Will the app support one account wallet per user at first, or multiple account types/sub-wallets? - Should transfer history and conversion history be included in the demo flow, or only the core actions listed?
