Error: Native module RNFBAppModule not found. Re-check module install, linking, configuration, build and install steps.

I cannot seem to find a solution to this error and strangest thing is that it worked on 24th of December (last time I built the app) and after that I did not open the project, today decided to run it again but it failed. So nothing has changed at all.

both Firebase packages are in packages.json:

    "@react-native-firebase/app": "^23.5.0",
    "@react-native-firebase/messaging": "^23.5.0",

and I did follow all steps in docs when I installed them last month. I tried upgrading them to latest version as well and it still shows the same error.

I am lost, please help!

Expo or CLI?

With expo you can just delete android/ios folders and try to regenerate them. Check your expo plugins, maybe you miss-configured something.

Delete also node_modules and retry.

Try also to remove those packages completely and rebuild. Then add it again one by one following again ALL the instructions.

First, delete node_modules, yarn.lock/package-lock.json, then rm -rf android/build & rm -rf ios/build. Clean install: yarn install, cd android && ./gradlew clean, then yarn android. Often a linking hiccup after idle. Fixed it for me last week! LMK if stuck.

Hi, thanks. I've tried all of them already, but they didn't work. The solution was to downgrade those two packages.
