Hot reload and hot restart improve developer speed but do not affect the app's runtime performance or battery use on users' devices. They are tools for development only, enabling quick UI updates without full app rebuilds.
Use hot reload to quickly see UI changes without losing app state. Use hot restart when you need to reset app state or apply changes to main() or global variables. Avoid unnecessary full rebuilds to keep development fast and smooth.
Hot reload and hot restart do not affect the final app bundle size or startup time for users. They only speed up the development cycle by reducing wait times when testing changes.
Flutter's hot reload and hot restart work similarly on iOS and Android during development. However, iOS requires a connected device or simulator with debugging enabled, and some changes may require a full rebuild due to platform restrictions.
Hot reload and hot restart are development tools and do not affect app store submissions. Ensure your final app build is fully tested without relying on hot reload. Follow Apple and Google guidelines for app stability and performance before publishing.
