 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`.
