Flutter Hot Reload
Flutter Hot Reload is a development feature in the Flutter framework that allows developers to instantly see changes in their code reflected in the running app without restarting it. It works by injecting updated source code files into the Dart Virtual Machine (VM), which rebuilds the widget tree and preserves the app state, enabling rapid iteration and debugging. This tool significantly speeds up the development process by reducing the time between making a change and seeing its effect.
Developers should use Flutter Hot Reload when building Flutter applications for mobile, web, or desktop to enhance productivity during the development phase. It is particularly useful for UI design, bug fixing, and experimenting with different layouts or features, as it allows for quick feedback loops without losing app state. This makes it essential for agile development workflows and iterative testing in Flutter projects.
