Dart is a client-optimized language by Google for fast apps on any platform. It is fast and optimized for UI, famous for the Flutter framework, also made by Google. Both Flutter and Dart are free and open-source.
This module wraps
dart-mode, with LSP features like code completion for
.dart files, syntax highlighting, debugging, closing labels, etc.
1.2. Module flags
flutterintegration and some sane defaults for Flutter development along with
hoverfor desktop development.
- Enable LSP support for
dart-mode. Requires :tools lsp and a langserver (supports lsp-dart).
No hacks documented for this module.
Make sure that the Dart SDK is on your
$PATH, and if using Flutter, make sure
the Flutter binary is on your
$PATH as well.
2.1. Installing Dart SDK
Before starting note that Flutter SDK will have a version of Dart. Therefore, there is no need to install Dart. If you want to use Flutter just see the next part.
The stable version of the SDK is in most major distributions repositories. If you find it necessary to install any other version or build from source, please refer to the official website at: https://dart.dev/get-dart
On Debian (also Ubuntu and its derivations):
On Arch Linux (and derivations like Manjaro):
2.2. Installing Flutter SDK
Due to complications with permissions, it is suggested not to use AUR or any automatic installation tools for Flutter SDK.
On any system just run the following commands to install Flutter, once you have met dependencies named on the site:
- Syntax highlighting and formatting for
.dartfiles provided by LSP
- Auto import
- Widget guide lines for Flutter
- Closing labels for constructors
- Run tests interactively
- Outline support via
- Emacs functions for running and debugging Flutter projects
4.1. Dart & Flutter
On Linux, the installers for Dart and Flutter use the
/opt directory, and this
module assumes that. However, you may set
lsp-dart-sdk-dir to your Dart
install directory and
flutter-sdk-path to you flutter SDK folder, to make sure
LSP can find the language server included with the Dart SDK.
Alternatively, these variables shouldn’t be necessary if you just include Dart
and Flutter on your
You will also need to setup your system for Android development if you intend to
use Flutter to develop mobile applications. Refer to your distributions package
manager for details. In most distributions the
/opt/android-sdk directory is
used, and you might have to change some permissions in this directory since it’s
owned by root. The Arch Linux wiki has a great guide on this here.
4.3. Flutter mobile development on desktop
Hover is an application that can run Flutter mobile apps on your desktop, this makes the mobile development a lot easier without the need to setup an Android emulator.
- On new installs to the
/optdirectory, you will likely need to edit the permissions of the
/opt/flutterdirectories (not to mention the Android SDK, as discussed above).
