error: package com.evollu.react.fa does not exist ?

Thank you for sharing your work.

I followed https://github.com/evollu/react-native-firebase-analytics/issues/20

Where should I look for this type of error?

```
/Users/edward3/Documents/projects/react-native/field-planner-mobile/android/app/src/main/java/com/ditchwitch/fieldplanner/MainApplication.java:25: error: package com.evollu.react.fa does not exist
import com.evollu.react.fa.FIRAnalyticsPackage;
^
/Users/edward3/Documents/projects/react-native/field-planner-mobile/android/app/src/main/java/com/ditchwitch/fieldplanner/MainApplication.java:39: error: cannot find symbol
new FIRAnalyticsPackage(),
^
symbol: class FIRAnalyticsPackage
2 errors
:app:compileDebugJavaWithJavac FAILED
```

I appended to settings.gradle

```
include ':react-native-firebase-analytics'
project(':react-native-firebase-analytics').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-firebase-analytics/android')
```
