+To clear cache, as of Expo SDK v42.0.0 on MacOS 11.5.2 (Big Sur):

+2. `yarn cache clean` (runs cache cleaner for yarn)
+3. `yarn` (reinstalls deps)
+4. `watchman watch-del-all` (kills cache in live updated watchman)
+5. `rm -fr $TMPDIR/haste-map-*` (to be honest, I'm not really sure)

+7. `expo start --clear` (restarts expo server and clears it's cache - `.expo` folder in your file explorer)
