问题
I've spent a considerable amount of time integrating react native into my existing IOS and android apps. And, it's working just fine. However, the fast refresh feature is not working at all.
However, fast refresh works just fine if I start a new project with react-native init.
Can anyone shed some light on the following:
How does the fast refresh feature work? (I know watchman is involved, but I believe that something is not telling my app when watchman detects a change in the JS)
Where I can look to begin troubleshooting this?
INFO:
React-native version 0.61.4
