A common question in Flutter interview questions and answers for experienced, don't miss this one.  Hot Reload: The “hot reload” allows developers to inject source code modifications directly into a running app to be seen immediately, without requiring a restart or loss of state. This feature is very useful as it helps us avoid the lengthy compilation process, which is particularly irritating when developers need to apply small changes in the app. Not having to wait for who-knows-how-long for the code to compile only to discover that you left out a semi-colon when tweaking the color of a button seems like a significant change for developers. It takes one second to perform its functionality.  Hot Restart: The “hot restart” loads the code changes into the VM and restarts the Flutter app, which results in losing the app state. It has a bit different functionality as compared to hot reload. In this, the preserved states of our app are destroyed, and the code gets compiled again from the beginning. Although hot restart takes longer than a hot reload, it's faster than a full restart function.
