Completion functionality for Dart Command-Line Interfaces built using CommandRunner.

ā In order to start using CLI Completion you must have the Dart SDK installed on your machine.
flutter pub add cli_completion
On your CommandRunner class, extend CompletionCommandRunner :
import 'package:cli_completion/cli_completion.dart'; class ExampleCommandRunner extends CompletionCommandRunner<int> { ...
This will make the first command run to install the completion files automatically. To disable that behavior, set enableAutoInstall to false:
class ExampleCommandRunner extends CompletionCommandRunner<int> { @override bool get enableAutoInstall => false; ...
When enableAutoInstall is set to false, users will have to call install-completion-files to install these files manually.
$ example_cli install-completion-files
Additionally, when enableAutoInstall is disabled a completion-script command is exposed. It prints the completion script for the current shell to stdout, so users can install it wherever they prefer:
$ example_cli completion-script >> ~/.zshrc
For an overview of how this package works, check out the documentation.
Handling completion requests should be straightforward.
If there are any checks (like analytics, telemetry, or anything that you may have on run or runCommand overrides) before running subcommands, make sure you fast track the completion command to skip all of the unnecessary computations.
Example:
@override Future<int?> runCommand(ArgResults topLevelResults) async { if (topLevelResults.command?.name == 'completion') { super.runCommand(topLevelResults); return; } // ... analytics and other unrelated stuff
If you are not using any zsh framework such as Oh My Zsh, you have to start the completion system manually.
Add the following lines to your ~/.zshrc file:
# Add this to the start of your zsh starter file (~/.zshrc)
autoload -Uz compinit
