react native crashlytics crashlytics().crash() not crashing

Question

I have the following versions for react native and react native firebase crashlytics.

package.json:

• react-native: 0.66.4
• @react-native-firebase/app: 14.2.4
• @react-native-firebase/crashlytics: ^14.2.4

android project gradle:

• com.google.firebase:firebase-crashlytics-gradle:2.8.1 android app gradle:
• implementation platform('com.google.firebase:firebase-bom:29.0.4')
• implementation 'com.google.firebase:firebase-analytics'
• implementation 'com.google.firebase:firebase-crashlytics'

According to the document running this line should create a crash.

crashlytics().crash();

This is only working on a release build. However, when I run the app on metro by react-native run-android, this does nothing, it did not create a crash. What can I do to make it crash by running the above line in metro environment?

• carlosdafield: I've only done this in ios but what worked for me was to turn the build to release and then turn off debug executable. Maybe that will help
• Chanaka Amarasinghe: I'm having the same issue. My app is not crashing

Answer 1

i found this solution its working for me

Create a firebase.json file in the root directory of your react-native app, with these Crashlytics-related keys set to these specific values:

{
 "react-native": {
 "crashlytics_debug_enabled": true,
 "crashlytics_disable_auto_disabler": true,
 "crashlytics_auto_collection_enabled": true,
 "crashlytics_is_error_generation_on_js_crash_enabled": true,
 "crashlytics_javascript_exception_handler_chaining_enabled": true
 }
}

• Chanaka Amarasinghe: No luck for me . Any other helpful something ?
• Jeff Padgett: While connected to metro, after this, i was able to crash the app using crashlytics().crash() from react-native-firebase. However, I am not seeing the crash appear in the firebase console yet, although it does now show "app detected, waiting for crash". I will wait another day and see if it appears.
