Build Troubleshooting

Unfortunately, the build system may fail to pick up local changes, such as installing new NPM packages or yarn linking a dependency. If the app is behaving strangely or not picking up your local changes, it may be due to build issues. To ensure that you're starting with a clean slate, close all emulators/simulators, stop the yarn watch process, and run:

yarn clean

# if you're going to `yarn link` any packages,
# do that here, before the next command

yarn watch:clean

# ...and then, in another terminal

yarn start:ios

# or

yarn start:android

If yarn link fails after going through these steps, try directly yarn adding the local files instead.
