remote_config_firebase.js

import remoteConfig from '@react-native-firebase/remote-config'

const fetchConfig = async () => {
  await remoteConfig().setConfigSettings({
    isDeveloperModeEnabled: __DEV__,
    minimumFetchInterval: 0
  })
  await remoteConfig().fetchAndActivate()
}

const getRemoteValue = key => remoteConfig().getValue(key).value

// In your React component (or any other):
import { useEffect } from 'react';

useEffect(() => {
  const callback = async () => {
    await fetchConfig();
    const sampleRemoteConfig = getRemoteValue('sampleRemoteConfig');
    
    console.log(sampleRemoteConfig);
  };
  
  callback();
}, [])
