React Native App crashes without error message when GestureDetector appears

[demenik]

Description

I am coding a React Native App that uses react-native-gesture-handler.

My initial setup where I first discovered the crash was a @react-navigation/native-stack NativeStack with two screens. When I show the screen with a GestureHandlerRootView at its root and a GestureDetector with a simple Gesture.Tap() gesture, the app crashes without any logs.

Steps to reproduce

I tried to simplify the app to see what causes the crash, so I changed my app to just the following code:

export default (): React.JSX.Element => {
  const test = Gesture.Tap().onBegin(() => console.log("Begin"));

  return (
    <GestureHandlerRootView style={{ flex: 1 }}>
      <GestureDetector gesture={test}>
        <View style={{ flex: 1, backgroundColor: "green" }} />
      </GestureDetector>
    </GestureHandlerRootView>
  );
};

Now the app crashes on launch, so I think the crash is caused by react-native-gesture-handler.

I'm using the new react-native architecture, installed all dependencies with CocoaPods, and included import "react-native-gesture-handler"; at the top of my index.js file.

I think we have the same or similar problem here #2839

I believe the changes necessary to support RN 0.74 on the new arch cause it to crash on 0.73. Would it be possible for you to check if it still crashes for you on 0.74?

Updating to react-native@0.74.0-rc.5 solved the issue. Thank you!

I sought out this bug, because I've been running into a similar problem all this past week.

• The stable 0.73 loads, but crashes when I gesture.
• I tried 0.72, and it does the same.
• 0.74 & 0.75: the app crashes on launch.

My specs are a bit different:

• Workflow: contains Expo
• Device: iPhone X (iOS 16.7.7)

Is Expo complicating React-Native's response, you think?

@Ever-It-Lazy I think your issue is a different one, as my 0.73 app already crashed on when a GestureDetector appeared and yours crashes when using one. Have you included the import 'react-native-gesture-handler'; at the top of your index.js file?

[Ever-It-Lazy]

I've replaced my App.js with your "green screen" example code in my environment.

• 0.73 and below loads, and the gesture works. (So apparently, our environments are different enough that I am not even replicating your problem?)
• 0.74 and above can't even launch. It's firing errors in the react-native code library.

You appear to be correct: I must be dealing with something different. It seems similar, because my actual app began much like yours: a NativeStack with two screens. I guess I need to spawn a separate bug report for investigation.
