React-native-picker-modal-view NPM

An alternative to Picker and PickerIOS components with an unified API and consistent look & feel on both plaforms. It's fully configurable and includes built-in support for text search and alphabetical index. Ideal for longer lists not suitable for "wheel-pickers".

Getting started

$ npm install react-native-picker-modal-view --save

$ yarn add react-native-picker-modal-view

Live Demo with Expo
