Q : Difference between ( Hot Reload ) and ( Hot Restart ) ?
A :
• both are allow you to see changes in your app , but there are key differences between them
1- Hot Reload :-
allows you to inject changes into the app’s running code without restarting the entire app.
Use it when you make small changes in ui
How it works: Flutter retains the app's state and applies changes to the widget tree, so you can see updates almost instantly.
It was very speed because it rebuild Partial of the widget tree
2- Hot Restart :-
restarts the app, which means it reinitializes the app and clears any current state
Use this when you make changes to the app’s initial state, like modifying variables in the main() function or updating dependencies, that Hot Reload cannot apply.
How it works: The app is restarted as if you were launching it for the first time, which includes losing all current app states (like inputs, navigation stack, etc.).
Slower, as the entire app is restarted ( because it build app again )
