For an emulator that mimics a Pixel 5 Device with Google APIs and ARM architecture (for an M1/M2 Macbook):

1. List All System Images Available for Download: sdkmanager --list | grep system-images

2. Download Image: sdkmanager --install "system-images;android-30;google_atd;arm64-v8a"

React Native Folder Structure

Motivations

• Sharing what has worked for me in different React Native projects
• Reusing screens in different parts of your app
• Easy to work separately in a feature
• Add an extra level (nested folder) only when necessary
• Don't overuse index.js for everything

# We need git and openssh to resolve `git+ssh` links in package.json
RUN apk update \
    && apk add git openssh

WORKDIR /usr/src
