Sidecar Analyzer

Enable a more personalized developer experience within the IDE.

Visit the official documentation site for work-in-progress tutorials and explanations of core concepts

This is an experimental package which is expected to change slightly until an official 0.1.0 release. However, the core architecture of Sidecar has been designed around the Dart-official package:analyzer APIs, and therefore any rule packages you may want to experiment with will be easy to port over to any future APIs

Motivation

Dart lints are incredibly useful for keeping a codebase clean and tidy, but code analysis use cases don't need to end at official rules. What if we could use these same tools to enforce highly-opinionated rules for a particular package ecosystem (BloC vs Riverpod) or for a particular app?

The goal of Sidecar is to enable a more personalized developer experience by allowing quick and easy access to the core lint and code assist tools of modern IDEs.

Usage

See the below guides for information on how to create and use Sidecar packages.

• Core Concepts
• Using Sidecar rules to analyze a Codebase

Example Sidecar Rule Packages

To explore how rule packages are created or to use them to work on your codebase, take a look at the following rule packages:

• design_system_lints
• dart_lints - Sidecar port of the official Dart lints, for benchmarking purposes

Installing the CLI tool

Some Sidecar tasks are easier with the CLI tool. To install the CLI, simply run:

dart pub global activate sidecar
