# How do I free space used by Flutter and Dart projects?

Each Flutter project builds into its own **build** folder, which can be large. Run `flutter clean` inside a project to delete it; it's rebuilt next time you run the app.

Packages are shared in the pub cache. `dart pub cache clean` empties it (packages download again when needed). If you also build for Android or iOS, those toolchains have their own caches — see [Android Studio and emulators](https://storagestudio.us/faq/mac-storage-basics/how-do-i-free-space-from-android-studio-and-emulators) and [Xcode](https://storagestudio.us/faq/mac-storage-basics/how-do-i-free-up-space-used-by-xcode).
