Building a React Native number pad feature from scratch

Modern mobile app onboarding often requires users to input a verification PIN, which can be enhanced by using a custom number pad in React Native apps. This guide demonstrates creating such a numpad, offering an alternative to split OTP input fields or conventional TextInput elements, for increased personalization and user engagement. The process involves setting up a React Native environment using Expo CLI, crafting a custom dial pad component, and integrating it into a simple app with navigation between Login, CustomDialpad, and Home screens. The numpad's functionality includes PIN input and validation, providing a secure user login experience, with visual feedback through animated dots representing entered digits. The article also discusses the pros and cons of various methods for implementing a number pad, such as using built-in TextInput, third-party libraries, or custom solutions, emphasizing the importance of customization and reduced app size. Overall, the tutorial aims to equip developers with the skills to create engaging and functional custom number pads for mobile applications.
