Flutter is an open-source UI software development toolkit created by Google. It is used to build natively compiled applications for mobile, web, and desktop from a single codebase. Flutter simplifies the development process by providing a consistent and expressive framework for building cross-platform apps with a rich set of pre-designed widgets.
PHP can be used as the backend server language to handle data storage, retrieval, and business logic for Flutter mobile apps. Flutter apps can communicate with PHP servers through HTTP requests (RESTful APIs) to fetch and send data. This separation allows for a clear distinction between the frontend (Flutter) and backend (PHP) components of the application.
Flutter offers hot-reload for faster development, a rich set of customizable widgets for building intuitive UIs, and a single codebase for deploying apps on both Android and iOS platforms. Its high performance, excellent documentation, and strong community support make it a popular choice for developers.
Flutter apps can use packages like Firebase Cloud Messaging (FCM) for push notifications. PHP can be employed to send notifications to the FCM server, and then the Flutter app can use FCM to receive and display these notifications to users.
Payment gateways typically support credit/debit cards, digital wallets (e.g., Apple Pay, Google Pay), bank transfers, and sometimes alternative payment methods depending on the region.
