Flutter is a popular open-source mobile app development framework created by Google. One of the key features of Flutter is its ability to use hot reload and hot restart to speed up the development process. But what exactly are Hot Reload and Hot Restart, and what is the difference between them? Let’s take a closer look.
Hot Reload
Hot Reload is a feature in Flutter that allows developers to make changes to their code and see the results immediately without having to restart the app. With Hot Reload, developers can make changes to the UI, add new widgets, change the layout, or modify the logic of their app and see the changes in real time.
Hot Reload is a powerful tool for developers because it allows them to experiment and iterate quickly, making it easier to develop and debug their apps. It also helps reduce development time and improve productivity.
Hot Restart
Hot Restart is another feature in Flutter that allows developers to restart the app from scratch while preserving the current state of the app. With Hot Restart, developers can make changes to the Dart code, the configuration, or the dependencies of their app, and see the results immediately.
Hot Restart is useful when developers need to make significant changes to their app that can’t be handled by Hot Reload. It also helps to ensure that the app is running in a clean environment, which can help prevent bugs and errors.
The Difference Between “Hot Reload” and “Hot Restart”
The main difference between Hot Reload and Hot Restart is the scope of the changes that can be made. Hot Reload is designed to make small, incremental changes to the app’s UI and logic, while Hot Restart is designed to make significant changes to the app’s code and configuration.
Hot Reload is fast and efficient, and it allows developers to make changes to the code and see the results immediately. Hot Restart, on the other hand, takes longer to restart the app, but it provides a clean environment for making significant changes to the app’s code and configuration.
Conclusion
Hot Reload and Hot Restart are powerful tools for developers in Flutter. Hot Reload is designed for making small, incremental changes to the app’s UI and logic, while Hot Restart is designed for making significant changes to the app’s code and configuration. By understanding the difference between these two features, developers can improve their productivity and speed up the development process.
