How does it use Flutter's built-in tools?

The skill provides specific instructions and snippets for using Flutter DevTools, the Widget Inspector, and advanced logging techniques like debugPrint and developer.log().

What is the primary benefit of the Systematic Flutter Debugging skill?

It prevents 'trial-and-error' coding by forcing a systematic investigation of the root cause before any code changes are proposed, leading to higher quality fixes.

What happens if a fix doesn't work after three attempts?

The skill includes a safety protocol that requires the developer to stop and re-evaluate the overall architecture rather than continuing to stack secondary fixes.

Does this skill work with state management libraries like BLoC?

Yes, it includes patterns for identifying common state management issues, such as missing providers in the widget tree or lifecycle-related state errors.

Mobile Development

Implements a rigorous four-phase methodology to identify root causes and resolve complex Flutter bugs without introducing regression.

About

The Systematic Flutter Debugging skill provides a structured framework for Claude to tackle technical issues in Flutter applications. By enforcing the 'Iron Law'—no fixes without root cause investigation—it prevents the common trap of applying quick patches that mask underlying problems. This skill guides the user through diagnostic logging, DevTools integration, and hypothesis testing, making it ideal for resolving widget build errors, state management bugs, and performance bottlenecks while maintaining high code quality.

Key Features

Strict four-phase debugging workflow: Investigation, Pattern Analysis, Hypothesis, and Implementation.
Built-in diagnostic patterns for Flutter DevTools, console logging, and debug widgets.
Specific guidance for common Flutter errors like 'RenderBox not laid out' and 'No ancestor found'.
Integration with git diff and log commands to track regressions caused by recent changes.
Mandatory verification step ensuring fixes are validated with analysis and testing.
1 GitHub stars

Use Cases

Troubleshooting complex widget layout constraints and rendering overflows.
Debugging asynchronous state management issues in BLoC or Provider architectures.
Investigating platform-specific build failures or intermittent test crashes.
