What is Complexity Indicator?

Editorial review
Complexity Indicator is a VS Code extension designed to help developers understand and improve the quality of their codebase by providing real-time complexity analysis. It displays a rich metrics dashboard directly in the sidebar, offering insights into various aspects of code health for the active file. While initially conceived with Flutter/Dart developers in mind, its functionality extends to any programming language, making it a versatile tool for a wide range of developers. The extension continuously updates metrics as you type, save, or switch files, ensuring you always have an up-to-date view of your code's complexity. It presents a comprehensive set of 9 metrics, including a weighted Complexity Score, Maintainability Index, Lines of Code (LOC), Function Count, Cyclomatic Complexity, Max Nesting Depth, Average Parameters, Comment Ratio, and Import Count. Each metric comes with clear explanations, healthy thresholds, and actionable advice, helping developers identify areas for refactoring and maintain clean, readable, and testable code. A status bar badge provides an at-a-glance complexity label (Low, Medium, High, Very High, Critical), allowing for quick assessment of file health.
