Environment

OS: macOS High Sierra 10.13.6
Node: 7.6.0

npm: 4.1.2
Watchman: 3.3.0

Description

In a custom component, propsType is used for specifying the props type of the component. No error was reported in the debug environment, but after release was packaged, it broke.

Code below

...
someComponent.propTypes = {
containerStyle: View.propTypes.style,
...
}
someComponent.defaultProps = {
containerStyle: null,
...
}
...

It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The ":rewind:Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

How did you package the release?

Just a guess: Proptypes have a performance overhead. That may be the reason why you're seeing that View.propTypes is null with the release build of your app.
