A Flutter package that simulates how a running app looks and behaves on other devices — screen size, pixel ratio, safe areas, locale, text scale, brightness, and target platform — without rebuilds or simulators. It integrates via a single enable() call and is controllable from Flutter DevTools, Dart code, or widget tests, and is disabled in release builds.
Use cases
- preview my flutter app on different screen sizes without a simulator
- test responsive layouts on notched phones and tablets while developing
- check how my app looks with large text scale or dark mode
- simulate locales and accessibility settings in a running flutter app
- verify safe area and home indicator layout issues early
- run widget tests against simulated device configurations
When to choose
- you build Flutter apps and want instant device/layout simulation during development
- you want to catch overflow, clipping, or safe-area bugs before shipping
- you need locale, text-scale, or platform overrides without emulators or rebuilds
When to avoid
- you need pixel-accurate native rendering or real device performance profiling
- your project is not Flutter/Dart
- you need automated cross-browser web testing rather than Flutter layout simulation
