### Usage with nix-shell {#ssec-dart-applications-nix-shell}
#### Using dependencies from the Nix store {#ssec-dart-applications-nix-shell-deps}
As `buildDartApplication` provides dependencies instead of `pub get`, Dart needs to be explicitly told where to find them.
Run the following commands in the source directory to configure Dart appropriately.

### Usage with nix-shell {#ssec-dart-flutter-nix-shell}
See the [Dart documentation](#ssec-dart-applications-nix-shell) for nix-shell instructions.
Flutter-specific `nix-shell` usage notes are included here. See the [Dart documentation](#ssec-dart-applications-nix-shell) for general `nix-shell` instructions.
#### Entering the shell {#ssec-dart-flutter-nix-shell-enter}
By default, dependencies for only the `flutterHostPlatform` are available in the
build environment. This is useful for keeping closures small, but be problematic
during development. It's common, for example, to build Web apps for Linux during
development to take advantage of native features such as stateful hot reload.
To enter a shell with all the usual target platforms available, use the `multiShell` attribute.
e.g. `nix-shell '<nixpkgs>' -A fluffychat-web.multiShell`.
