Hi guys. I've been strugling with this issue and as I searched for that, It turned out that it causes because I haven't linked this package properly. but It's not true since I carefully checked the app/build.gradle and setting.gradle and ...

"react-native": "^0.51.0"
"react-native-picker": "^4.3.5",

Hey guys, I think that react-native link is broken now. I had same issue and I fixed it by adding:

new PickerViewPackage(),

in MainApplication.java:

protected List<ReactPackage> getPackages() {
    return Arrays.asList(
        new MainReactPackage(),
        ...
        new PickerViewPackage()
    );
}

Just make sure that there is import:

import com.beefe.picker.PickerViewPackage;

at the top of the file.

Found issue where attempting to call `._init()` on the native module
threw a red screen of death in React Native v0.54.

In the docs for RN v.54, the tutorial says nothing about the RCT
prefix. Removing this, inline with the current documentation, seems to
have fixed the problem.

There seemed to be issues with the gradle file, preventing builds on
Android. I had to bump the compiler SDK versions for it to build so I
could test. The `Build.VERSION_CODES.O` constant is apparently only
available after API level 26. Changing the compiler SDK version,
whilst keeping the target the same fixed the build.
