I'm working on a Flutter app and I've noticed that whenever I save my app to see the updated changes, my entire app reloads. I would expect the page that I have open to hot reload with my new changes on it.

I think that the way my widget tree is organised could have an effect on this. My entire app is wrapped in a widget that runs at startup that initialises to a ServicesLoadingState. Then, after the services have finished starting up (in the BLoC), it yields a ServicesReadyState and then all my widgets are drawn. I think when I hot reload, the state of the topmost widget switches back to ServicesLoadingState, reloads the services, and shows me the behaviour I'm experiencing.

I've tried googling "flutter hot reload restarts app" but I haven't found any good tips on how to prevent this. How can I stop hot reload from restarting the entire app?

Can you check if you are using a global navigatorKey in your MaterialApp ?

I faced the same issue and I found that it was due to navigatorKey in my MaterialApp.

So when I'm in dev mode, I comment the navigatorKey property.
