## Supported Versions | @react-native-picker/picker | react-native | react-native-windows | | --- | --- | --- | | >= 2.0.0 | 0.61+ | 0.64+ | | >= 1.16.0 | 0.61+ | 0.61+ | | >= 1.2.0 | 0.60+ or 0.59+ with [Jetifier](https://www.npmjs.com/package/jetifier) | N/A | | >= 1.0.0 | 0.57 | N/A | ## Getting started `$ npm install @react-native-picker/picker --save` or `$ yarn add @react-native-picker/picker` ### For React Native v0.60 and above (Autolinking) As [react-native@0.60](https://reactnative.dev/blog/2019/07/03/version-60) and above supports autolinking there is no need to run the linking process. Read more about autolinking [here](https://github.com/react-native-picker/cli/blob/master/docs/autolinking.md). This is supported by `react-native-windows@0.64` and above. #### iOS CocoaPods on iOS needs this extra step: ``` npx pod-install ``` #### Android No additional step is required.

Windows (expand for details)

#### Windows Usage in Windows without autolinking requires the following extra steps: ##### Add the `ReactNativePicker` project to your solution. 1. Open the solution in Visual Studio 2019 2. Right-click Solution icon in Solution Explorer > Add > Existing Project Select `D:\dev\RNTest\node_modules\@react-native-picker\picker\windows\ReactNativePicker\ReactNativePicker.vcxproj` ##### **windows/myapp.sln** Add a reference to `ReactNativePicker` to your main application project. From Visual Studio 2019: Right-click main application project > Add > Reference... Check `ReactNativePicker` from Solution Projects. ##### **app.cpp** Add `#include "winrt/ReactNativePicker.h"` to the headers included at the top of the file. Add `PackageProviders().Append(winrt::ReactNativePicker::ReactPackageProvider());` before `InitializeComponent();`.

#### MacOS CocoaPods on MacOS needs this extra step (called from the MacOS directory) ``` pod install ```
