Flutter Hot Restart
Flutter Hot Restart is a development tool in the Flutter framework that resets the app state and reloads the code from scratch while preserving the UI layout and structure. It is faster than a full restart but slower than Hot Reload, as it reinitializes the app's state and rebuilds the widget tree. This feature is particularly useful when making changes to app initialization code, global variables, or static fields that Hot Reload cannot handle.
Developers should use Flutter Hot Restart when they need to reset the app's state after modifying code that affects the initial setup, such as changes to the main() function, global configurations, or state management logic. It is essential for debugging scenarios where Hot Reload fails to apply changes due to state dependencies, ensuring a clean slate without losing the development environment's speed. This tool streamlines the iterative development process in Flutter by reducing downtime compared to full app restarts.
