Recommended .gitignore for react-native

I'm trying out react native and ejected into a full build environment. Sadly, the eject-script did not create a sensible .gitignore file.

Not knowing a lot about app-development, I wonder what directories I could .gitignore here?

I'm guessing:

• android/build
• android/app/build
• android/.gradle/

Are these alright, or are there any more directories I should .gitignore?

Below is the .gitignore file ships with the react-native init command. You can find the full file here.

# It is recommended to not store the screenshots in the git repo. Instead, use Fastlane to re-generate the
# screenshots whenever they are needed.

*/fastlane/screenshots

# Bundle artifact
*.jsbundle

This is what I am using.

The content should be save in the .gitignore after ios and android envirment like (signature, config file) init,

Then the auto generate file like (index.android.bundle,main.jsbundle) need to be removed using git rm -f ---cached (file path) ,then commit it,then create a new one.

That's becasue the auto generate file don't need to be commited.

This is the newer version of .gitignore for react-native projects https://github.com/facebook/react-native/blob/master/.gitignore

Adding package manager lock file is optional. You can add them by adding package-lock.json for npm or yarn.lock for yarn, at the end of the below code.
