Downgrading @react-native-picker/picker to 1.8.3 worked for me. 💯

Not really closed, as this is an issue, out the box the Picker fails. Due to this issue

Having this issue in iOS Simulator, but after installing this @react-native-picker/picker : ^1.9.4" package issue fixed.

[raldred]

Maybe fixed by 1.9.6 then https://github.com/react-native-picker/picker/pull/190

[ajoykarmakar459]

This fixed the issue for me -

npx react-native link
android -
re-run react-native run-android command

ios - 
cd ios
pod install
re-run react-native run-ios command

The solution is to install correctly the lib and its dependency:

npm install react-native-picker-select
npm install @react-native-picker/picker

If the error always persists, just enter this command line to link manually the lib: npx react-native link

Enjoy !

Doing this I get Invariant Violation: Tried to register two views with the same name RNCAndroidDropdownPicker Did you have this problem too and managed to solve it somehow?

Took quite a few gathered steps to get the update working for me, you might not require all of these, but maybe they can help.

Firstly, I did update to react-native v0.63.4 (probably not necessary).

These steps come after upgrading this, react-native-picker-select, package to 8.0.3

1. npm install @react-native-picker/[email protected]

2. Add to package.json

    "resolutions": {
        "react-native-picker-select/**/@react-native-picker/picker": "1.8.3"
    },

3. react-native link @react-native-picker/picker

4. Add to android/app/build.gradle

dependencies {
    ... 
    implementation project(':@react-native-picker_picker')
}

5. watchman watch-del-all && rm -rf node_modules/ && yarn cache clean && yarn install && yarn start -- --reset-cache

6. cd android && ./gradlew clean

7. cd ios && pod install

Hello Everyone!

I was facing the same issue

Invariant Violation: requireNativeComponent: "RNCAndroidDialogPicker" was not found in the UIManager.

when I installed npm install react-native-picker-select and used their Basic Usage example in React Native CLI.

import RNPickerSelect from 'react-native-picker-select';

export const Dropdown = () => {
    return (
        <RNPickerSelect
            onValueChange={(value) => console.log(value)}
            items={[
                { label: 'Football', value: 'football' },
                { label: 'Baseball', value: 'baseball' },
                { label: 'Hockey', value: 'hockey' },
            ]}
        />
    );
};

I tried installing another package named @react-native-community/picker using npm install @react-native-community/picker in your project's root directory. This helped me solve the error.

Try Installing the same package and link it with your project (if required).

Enjoy!

got this error as well but if you stop the simulator (weather it's expo simulator or ios or whatever) and restart it it may go away - if you npm / yarn install while simulator is running in some other terminal, and just navigate to the window you added the Picker to this error will come up
